Vital Signs                                      Twin Oaks Enterprises Brunswick MO


To do a better job of taking care of your horse you need to pay attention to the way he acts when he feels good.  Notice the way he carries his head, moves at a walk, his heart rate at rest and after work, his temperature, and the area around his eyes and eye color.


Normal temperature of an adult horse is from 99.5 to 101 degrees.

However foals are slightly higher 101 to 103


Normal Respiration 16-24 breaths per minute


Normal Pulse rate 40-60 beats per minute


GI Tract Motility Left flank several pops and gurgles per minute
And on the right flank 1 to 2 Cecal contraction sound per minute
Skin pinch Normal the skin should return to flat within 1-2 seconds
Capillary Refill Time 1-2 seconds should go back to light pink color

Knowing these vital signs can be very important in the event of a serious injury or sickness.
You should practice taking these readings when you are not excited or scared, so you will be able
to take accurate readings easier if there is an emergency.

To take Temperature you will need a rectal thermometer tied securely to a string about a foot long with a clip on the end of the string. Tie your horse up or put in stocks. Have someone hold the tail out of the way. Standing to the side so you don’t get kicked clip the end of the string to a bunch of tail hairs, so if the thermometer gets knocked out of your hand it won’t hit the ground and break. Lubricate the Thermometer and insert carefully in the rectum. Try to keep the horse as still as possible. Leave it in for a couple of minutes and then remove and take the reading. Be sure to clean the
thermometer before using on another horse.

To take the Respiration Rate. When your horse is at rest simply count the number of breaths per minute.

To take Pulse Rate, find a main artery that is close to the surface. Under the jaw, or just behind the elbow at the girth, or under the fetlock just above the bulbs. With your index finger placed on the artery count the pulses for 30 seconds and double, to get rate per minute. If the horse won’t stand well you can do 15 seconds and multiply by 4. 
 

How to Take Your Horse's Digital Pulse
First Aid: A simple four-step method for finding your horse's pulse.  It will be harder to find on a resting horse than one that has just been excecised.  If you can feel a throbbing pulse it is a good indication of infection in the foot.

Step 1: Squat down on the side of your horse's left front leg, and place your index finger around the left side of the fetlock joint at its lower edge.

Step 2: Apply pressure with your finger, and strum (run your finger from side to side, as though strumming a guitar) around the fetlock joint, until you feel a cordlike bundle (consisting of vein, artery, and nerve) "snap" underneath your touch.

Step 3: Apply pressure to this bundle for 5 to 10 seconds until you feel a pulse. (Note: If you can't find a pulse, adjust the amount of pressure you're placing on the bundle. If you press too hard, you'll cut off blood flow-therefore the pulse. If you press too softly, you won't create enough resistance to feel the pulse at all. Don't get frustrated-practice!)

Step 4: Now here's the tricky part. You need to determine whether your horse's digital pulse is throbbing abnormally. It helps to know what a healthy pulse feels like-but you can't always find a pulse on a healthy leg/hoof. It might be too faint. On the other hand, you'll know he has a problem if you can easily find his digital pulse. (If you're not sure, consult your veterinarian or knowledgeable friend.)

Step 5: Repeat Steps 1 through 4 on your horse's other three legs.


To listen to the GI Tract movements. Make sure your horse will let you place your ear to his side just in front of his flank and listen.

Pinch test to check for hydration. Just pinch the skin on the neck and see how quickly it goes back to normal...If it goes right back your ok if not your horse is dehydrated and may need fluids and electrolytes.

Capillary Refill Time is to check the circulatory system. Raise your horses upper lip and press on it with your thumb. Then remove your thumb the thumb print will be white and should refill to light pink in 1 to 2 seconds.

Should the gum color becomes bluish looking you have a very serious problem. You need to call a vet immediately. He will need to start to pump a saline solution I V because your horses veins are collapsing and death is near with out very prompt action. 

Knowing your horses body language is very important. If he looks droopy, won’t eat, is biting at his side, laying down and getting up frequently you maybe dealing with colic. Try to become familiar with the signs, you could save your horses life.

Sweating on the neck and shoulders can be a sign of shock, pain or strain. If your horse is not cooled out in 10 to 15 minutes in 70 to 75 degree weather you may have a problem keep and eye on him.  Sweating in just one area can be a sign of injury or strain.

 

Learn the Points of a horse

Print worksheet and copy to learn the parts of your horse.  Important to know parts so you could explain and injury or understand how to apply a cue to your horse.


Manure, not a pleasant subject, that we all have scooped a lot of.  Possibly without giving it the thought or attention it needs.   Manure is your first clue trouble is brewing in side your horse's gut.  The manure your horse produces can warn the observant horse owner about problems before they become apparent on the outside.  A healthy horse's manure will be brown to green depending on what he/she is feeding on hay, grain, grass of a combination of the three.  It should form in soft oval shaped apples. When it varies from this you may need to take action.  Soft or loose manure can mean a change in diet, a change in environment, stress from traveling or some other source, the amount of grain fed, or first grass in the spring.  You may need to limit the time your horse has to graze, especially if he/she is an easy keeper, or an older gelding.  It might just head off a case of founder.  It can also be a sign your horse is wormy, or isn't utilizing his/her feed correctly, such as to high protein, or missing mineral or salt.

 

Healthy, on hay and grain    Not serious watch           This horse has a problem.   

               

She is not on grass and has not had a change in feed.  By process of elimination the next thing I would do is worm her.  Then watch for worms in the manure.  If you see worms (usually with in a day or two) you probably have the problem in hand, but if it continues for a week you should get another opinion.  When her manure is like this she is not utilizing her feed, and left alone she will start losing weight and by the time you notice the weight loss it is a costly, time consuming process to get the weight back on.

 

Winter Care  Temperatures between 15 and 60 degrees F are considered energy neutral for horses. This means that within that temperature range, horses don’t require extra energy or calories to stay warm or cool. However, this assumes that the wind is not blowing and the horse’s hair coat is not wet, because both conditions increase the horse’s caloric needs. 

An idle horse in comfortable weather will consume roughly 3 percent of his body weight in feed every day and at least half of that should be forage.

Horses instinctively know when they need extra calories to increase body temperature and maintain weight. Unfortunately, most horses are on a fixed diet and when additional calories are required to keep them warm or to maintain body weight, they are at the mercy of their owner’s ability to adjust the feed ration.  When feeding horses in cold weather, it is important to know two things:
  1. Don’t be deceived by woolly winter hair coats that can make a horse look fat. During cold weather, horses that are not receiving adequate rations first burn stored fat and then protein from muscle tissue to fuel daily activities. Initially, fat reserves stored along the ribs, crest of the neck and rump are used. Then the muscles in the neck, shoulder and hindquarters are sacrificed. So when trying to assess body condition on a winter-coated horse, run your hands over the horse’s back, hips and ribs to determine if he is losing weight. If you are uncomfortable estimating weight loss through palpation, use a weight tape to check the horse’s weight in the late fall and then weekly throughout the winter.
  2. Keep in mind that hay – not grain – is the best feed to help a horse generate body heat. The heat of digestion from five pounds of extra hay will raise the average horse’s core body temperature 1.2 degrees for nearly four hours. Forage is digested in the horse’s large intestine through bacterial fermentation, which not only provides nutrients but also generates heat. Concentrates such as corn and barley are low in fiber and are digested in the small intestine through enzyme activity, producing little heat.

Hooves

  Your horses hooves grow at a rate of about .25 (1/4) inch per month, and takes about a year for the new growth at the coronet band to reach the bottom of the foot.  When there is trauma to the coronet band the injury will all ways show as a ridge or bump in the hoof.  One reason it is important to use bell boots or some kind of protection for your horses hoof when engaging in high risk activities.  The usual recommendation for resetting or trimming is every six weeks, depending on usage and type of terrain your horse is on.   Un-shod horses running on pasture will ware there feet down and may not require trimming as often as a horse that is stalled 24/7 with little exercise.

How do you perform CPR on a foal in distress?

Cardiopulmonary resuscitation (CPR) is the restoration of spontaneous circulation and breathing and is used in cases of cardiopulmonary arrest, defined as sudden cessation of spontaneous and effective respiration and heartbeat.

This most often occurs in foals suffering from asphyxia or lack of oxygen before and during birth. Although you should call your veterinarian if you suspect a problem, following the “A-B-C-Ds” of resuscitation might help save your foal’s life.

 

“A” – Assessment/Airway

Following a normal delivery, observe the foal for the first 20 seconds to ensure he is breathing. Following a dystocia (difficult birth) or Caesarean section, dry the foal vigorously with his head lowered to help clear the fetal membranes and fluid from the nose so he can breathe (foals are obligate nose breathers; don’t worry about clearing the mouth). Avoid holding the foal upside down to try to increase drainage.

After a few initial gasps and within 30 seconds, a normal foal should be taking 60-80 breaths per minute. The heart rate should be 60-70 beats per minute. Foals that continue gasping for more than 30 seconds and have a heart rate less than 50 beats per minute, or no heartbeat, require immediate resuscitation.

 

“B” – Breathing

Intubation (through the nose or mouth into the trachea) is the best way to provide an airway and breathe for the foal. Only a veterinarian or trained veterinary technician should intubate. Until your vet arrives, you can use mouth-to-nose resuscitation or a mask resuscitator, although there is a risk of inflating the stomach using a mask resuscitator. Place the foal on its side on a firm, dry surface. To perform mouth-to-nose resuscitation extend the foal’s neck, make sure the nose is cleared, and hold off the down nostril with one hand while breathing into the up nostril. Deliver 10 to 20 breaths per minute; breathing too rapidly can be detrimental. Each breath should visibly expand the foal’s chest.

 

“C” – Circulation

After 30 seconds of breathing for the foal, reassess to determine if chest compressions are necessary – they aren’t required in all cases. If there is no heartbeat, it’s less than 40 beats per minute, or it’s less than 60 beats per minute and not increasing, chest compressions are indicated.

Place the foal on a firm, dry surface, position rolled towels or sandbags underneath the thorax, and put the resuscitator at the foal’s spine. Kneel or stand and place your hands on top of each other just behind the foal’s triceps at the highest point of the thorax (see photo above). With the shoulders directly over the foal and the elbows locked, use the entire upper body to compress the thorax. Compress the entire thorax, not just the heart. There is a risk of fracturing ribs or lacerating the lungs with fractured ribs, but you shouldn’t avoid chest compressions.

Perform compressions at a rate of 80-120 per minute. Relieve the resuscitator every two to three minutes, if possible, because he/she will quickly become fatigued. Continue breathing for the foal throughout the compressions. If there is only one person available, give one breath for every 10 chest compressions.

 

“D” – Drugs

Always perform ventilation and compressions first. If there is no heartbeat after one minute of these activities, drug therapy might be indicated. However, human studies show prognosis is poor at this point and drugs might not help.

When to Stop

If you’ve performed CPR for 15 minutes with no response, success is unlikely. If the foal is responding, continue CPR. Once a foal’s heartbeat is faster than 60 beats per minute, you can discontinue chest compressions. Once he’s taking more than 16 spontaneous breaths per minute and has a heart rate of 60 beats per minute or faster, you can stop breathing for the foal.

After resuscitation, foals require intensive care and monitoring, as they have suffered a hypoxic event and might suffer cardiac arrest. They should be referred to a clinic or hospital for such care.

Ask your veterinarian to help you assemble a “crash cart” for the barn.

Common Hoof Problems

 

Nip hoof problems in the bud before they negatively affect your horse’s health.

Caring for your horses and their unique needs is important to their health and well-being. Horse hoof issues are more common than one may think and should be properly addressed before they negatively affect the health of your horse. Below are four common hoof problems:

  1. Abscess – An abscess is an infection of the sensitive tissue of the foot. As a result, your horse might suffer from varying degrees of lameness, depending on the severity. Symptoms include the hoof being hot and an increased pulse. Once the abscess begins to drain, lameness usually subsides. Abscesses are most commonly found with hoof testers.

  2. Crack – A hoof crack is a visible vertical crack in the hoof wall. Cracks are referred to by their location, such as toe, quarter, heel or bar crack. They can be superficial to the hoof wall or can deeply penetrate the sensitive structure. Healthy hooves do not crack as easily as dry, brittle hooves. The only treatment is to immobilize the hoof crack, preventing it from growing.

  3. Sole Bruises – Sole bruises appear as red spots or specks on the sole and frog. They will vary in size, based on the extent of blood vessels affected. Bruises are often caused by trauma from a sharp object or excessive weight-bearing of the sole on rocky ground. Barefoot horses should be trimmed so they walk on the hoof wall, but hooves that are trimmed too short are easily bruised on any ground. Bruises should rarely cause lameness unless they are severe.

  4. Corns – Corns start out as bruises of the sensitive sole in the angle formed by the hoof wall and bars. This angle, where the wall and bars meet, is the seat area where corns originate. Corns can be either dry or moist. A dry corn is a red bruise in the seat of the corn area caused by the horn tubular filling with blood from a ruptured vessel. A moist corn is yellow, with serum present. Corns can be caused by many things, including overtrimming the heels, heel calks, short-heeled shoes, unlevel shoes or leaving the shoes on too long.


Learn how you can help your foal’s legs straight and hooves healthy with these tips.

 

From the American Farrier’s Association, an AQHA educational marketing alliance partner

There are many steps that need to be taken at foaling time and shortly thereafter to optimize mare and foal health, vigor and longevity. Horse owners who are raising foals should have an understanding of the importance of early hoof care and the continuous routine care necessary to optimize proper hoof and leg structure, performance and long-term soundness of their equine friend.

Some foals may be born with major hoof and leg deviations that will require more than hoof-trimming techniques (these foals may require veterinary care or surgery) to minimize these deviations. Amazingly, proper hoof trimming can adjust and improve minor deviations and, more importantly, maintain correct leg structure in foals born with adequately correct legs and hooves. It is equally amazing what neglect or lack of proper trimming will do to foals that have only slight leg deviations or even foals born with straight legs. Although there are few foals born with “perfect” legs, these tips will help foal owners address minor deviations and keep the perfect foal correct.

The First Trim

Horse owners often wonder when to trim their foal for the first time. Some suggest that no hoof care is needed until the foal is a year old or even worse, until started into riding training. Waiting a year or even two is never acceptable when considering the welfare of the animal. Hooves get long, wear or break unevenly or, even worse yet, don’t wear or break at all, thus escalating leg strain and deviation potential.

As the foal matures, bones harden and joints formalize making corrections impossible. All corrective trimming and efforts to maintain the correct form and function of the leg must be implemented well before the foal is one year old. Corrective trimming after a horse is one year old will usually cause more damage and leg stress over time than it will correct because the bone growth plates are closing (becoming inactive). The greatest successes are a result of early innovation and continued efforts to make corrections slowly with only slight adjustments each trimming. This will allow the limb to self correct as much as possible while causing minimal stress as the bones and joints are modified to a more correct, sound stance and structure.

The foal should have its first trim at 3 to 4 weeks of age if the legs are fairly straight and normal. Earlier intervention should be applied if needed to make major adjustments. Remember, “the earlier the better” when it comes to trying to modify a deviated bony column. As most foals are born with some deviation, early intervention helps maximize the success of corrective trimming efforts.

When a foal is born, its hooves, particularly on the front, are fairly pointed. The point on the front feet aids in positioning and delivery through the birth canal, plus it aids in the tearing of the placenta upon delivery. Once the foal is born, the pointed feet become a liability. Due to the hoof shape, the foal is unable to break (roll over the toe when stepping) directly over the front of the hoof. This causes the flight path to break to either the outside or inside (most common) of the point, causing the foal to become toed in (pigeon toed) or toed out (splay footed). Neglect at this point allows additional wear during breakover, thus contributing to additional deviations if neglected.

A point to remember: “All hoof and leg deviations from the ideal get worse with neglect of hooves and excess growth and can even become more deviated in their form and function.”
– Scott S. McKendrick, certified journeyman farrier

Correcting Minor Deviations

The square-toe system works well to maintain correct legs and to help correct minor deviations. Squaring the toe of a 3- to 4-week-old foal will counter the effect of the sharp toe (front or rear) and provide a straight and easy breakover position, thus helping the legs for a correct bony column structure without deviation to the inside or outside through improper wear. It is, however, possible to adjust the squared or rolled toe position slightly off center to the outside or inside of the hoof, depending on which deviation needs correcting.

As a general rule, if the foal toes out, you will lower the outside half of the hoof wall (with nippers or rasp) and adjust your square toe slightly off center to the outside. If the foal toes in, you will lower the inside of the hoof wall on the bottom of the hoof and place the squared toe slightly to the inside.

The off-center squares will encourage breakover in that direction and counter the existing wear that the current deviation is causing to the hoof. These adjustments should be made slowly with minor changes every three to four weeks, depending on hoof growth.

Utilization of hoof epoxies (glues) may be useful and even necessary to help in correcting major limb deviations where trimming is insufficient to correct the flight pattern and leg stance. These epoxies can be used to build up the low (worn) side of the hoof, encouraging breakover to the opposite side. The use of half shoes, glues/epoxies, or wedged shoes may be necessary to correct deviations.

Summary

Providing an accentuated breakover for the toe of a young foal, early in its life, will do more for the good of the horse’s legs than any subsequent trimming or shoeing after a year of age. Regular (every three to four weeks) trimming will maintain the good work started early and allow for solidification of the bony column in as straight and correct a line as possible.

A general “rule of thumb” for care of the mature horse includes trimming the non-use horse every 10 to 12 weeks, trimming a barefoot horse in use every three to four weeks and/or trimming and shoeing the shod horse every six to eight weeks.

Start trimming early and keep it up throughout the life of the horse, and you will enhance the longevity of the form and function of your equine friend. Remember, you will do the most good before the foal is a year old – so don’t wait!

Colostrum for Foals

Make sure your newborn foal gets the best chance at a healthy first year.

By Dr. Thomas Lenz for The American Quarter Horse Journal

As you probably know, colostrum is the thick yellow honey-like first milk produced by a mare just prior to foaling. It differs tremendously from the white milk she will produce throughout the rest of her lactation. Many horse owners worry that their mare will not produce enough milk for the foal that’s on the way. Check out Horse Lactation to read about how to ensure that your mare is producing enough good-quality milk for her foal.

Why It’s Important

Unlike that of a human, the mare’s placenta does not allow the transfer of antibodies (protective proteins that fight off infection) directly from her bloodstream to her foal’s during pregnancy. As a result, foals are born with little or no protection against infectious disease. However, the mare does pass along antibodies in her colostrum that will protect the foal during the first few months of its life, until its own immune system matures and is capable of fighting disease on its own. Foals that do not receive adequate colostrum suffer from a syndrome called failure of passive transfer (FPT), which is estimated to affect up to 25 percent of newborn foals and predisposes them to life-threatening diseases.

We’ve known for years that foals should ingest roughly 2 quarts of colostrum during the first three hours of life to ensure maximum antibody transfer and protection. At roughly eight hours after birth, the foal’s intestinal lining begins to “close,” and its ability to absorb antibodies decreases gradually until it ceases antibody absorption completely after 18-24 hours.

 

Because the average foal takes in only about a half pint of liquid per feeding, it is crucial that it is up and nursing as soon as possible. If a foal cannot stand to nurse, it is always a good idea to milk the mare and give the foal colostrum via a bottle or bucket. In some cases, it might be necessary for a veterinarian to provide the colostrum via a stomach tube.

Causes

Failure of passive transfer can develop for a number of reasons. The mare might not produce adequate quantities of colostrum. This is especially true in mares older than 15 years of age or on fescue pastures. The mare also can drip milk for a few days prior to foaling and deplete her store of colostrum.

Mares that drip milk (premature lactation) for more than 24 hours pre-foaling will seldom provide the foal with adequate levels of colostrum. Foals can also suffer from FPT if they fail to nurse, are premature or suffer from disease. Fortunately, there are a number of instruments and tests your veterinarian can use to determine if the mare’s colostrum is of good quality and contains adequate amounts of antibodies.

Blood samples collected from the foal 12-24 hours after birth will also determine if the foal has ingested and absorbed adequate amounts of colostrum. If the test determines the foal hasn’t received adequate amounts of colostrum, it can be provided antibodies via commercially available plasma administered intravenously. As in all medical problems, the best defense is preparation. Visit with your veterinarian several weeks prior to the anticipated foaling date to establish an action plan in the event something goes wrong.

Vital Functions

Besides providing life-protecting antibodies, colostrum is also an important energy source. The foal’s internal energy source is very low, and glycogen (sugar) stores present at birth provide only two hours of energy to the unfed newborn foal. Fat stores are also very low.

Therefore, the newborn foal is at risk for malnutrition and subsequent weakness from the very start unless it receives nourishment. One good feeding of colostrum provides up to 18 hours of adequate blood glucose and energy to sustain the foal. Colostrum also contains a protein called lactoferrin that sequesters iron and prevents bacterial colonization of the intestinal tract, which in turn prevents foal diarrhea. In addition, colostrum contains several components that aid the foal’s white blood cells in fighting off invading bacteria.

 

Infectious diseases enter the foal’s body through the umbilical cord, the lungs or the intestinal tract. Because the intestinal tract is the most common entry point in the young foal, it’s easy to appreciate the importance of colostrum’s protective mechanisms.

Bank It

Because of the obvious importance of colostrum to the newborn foal, many broodmare farms and veterinary clinics maintain stores of frozen colostrum to be used in an emergency. To bank colostrum for future use, it is usually possible to collect at least a half pint of colostrum from a mare without depriving her own foal. Of course, the colostrum should be collected immediately after the foal first nurses and should be tested to ensure its quality. Your local equine veterinarian is the best source of information on specific procedures and recommendations to ensure that your newborn foals get a healthy start in life.

 


 Summer Heat

As the weather gets warmer, you need to be cautious of the effect of heat on your horses.

From The American Quarter Horse Journal

Summer is picture-perfect weather, putting outdoor riding at the top of American Quarter Horse owners’ lists of favorites. But the effects of hot weather can be brutal to our equine friends. When temperatures soar into the 90s and 100s, your horse’s health can quickly cross into the danger zone, especially when exercising.

Heat builds up during exercise and must be released. In hot conditions, avoid heat stress, which can progress to heat stroke, by observing your horse’s condition and minimizing excessive exercise.

Dehydration

Dehydration is an unmistakable sign of heat exhaustion. When a horse loses water through perspiration faster than it can be replaced, he becomes dehydrated. A simple “pinch” test can help you determine if your horse is dehydrated. Pinch a small section of skin on your horse’s neck or shoulder and release. If the skin snaps back into place, your horse is in the clear. If there is a delay, he could be dehydrated.

 

Treat the Heat

If you think your horse is suffering from heat stress, stop riding and get him to a cool, ventilated area. If you suspect heat stroke, call your veterinarian immediately. While you wait for the doctor, move your horse out of the sun. Find a breeze or provide fans to cool the horse as best you can. Spray your horse with cool water — beginning with his legs first — to help lower his body temperature. Scrape excess water off quickly because it soon rises to the temperature of the over-heated horse.

Be sure to tell your veterinarian if you think your horse is having a heat stroke. In critical situations, he or she might advise you to apply ice packs or water-soaked towels to the horse’s legs and other areas that have large veins. If you use wet towels, be sure to change them often.

 

Signs of Heat Stroke:

  • Temperature above 104 degrees F. (A normal temperature is 99-100.8 degrees F.)
     
  • Rapid heart and pulse rates that don’t recover after exercise.
     
  • Rapid breathing that doesn’t slow after exercise.
     
  • Less sweat than expected.
     
  • Hot skin (might progress to cold if skin circulation shuts down).
     
  • Signs of dehydration, including loss of skin elasticity, sunken eyes, tacky membranes and cessation of urination.

Non-Steroidal Anti-Inflammatory Medications and Equine Patients

Non-steroidal anti-inflammatory medications (NSAIDs) are a class of agents best recognized for anti-inflammatory and analgesic (pain suppression) properties. An important clinical use of this class of medication is to improve patient status and minimize pain. The NSAIDs are a class of medication that were originally used in veterinary medicine in 1875. Indications for use included the control of fever, inflammation with pneumonia, and lameness associated with arthritis.

The mechanism of action for NSAIDs is important to understand, particularly when we consider the use of several of these agents concurrently (stacking) and recognize that many of the agents used in equine medicine target the same enzyme system. This is why stacking or high dose NSAID therapy may lead to drug toxicity. The fundamental principle of these medications is to inhibit the enzyme called cyclooxygenase (COX). What we have learned in the past two decades is that there are several forms of COX (1, 2, and 3) and some medications target one enzyme, preferentially. The NSAIDs described in this discussion will focus on general COX inhibitors; those that target COX2 preferentially are typically referred to as the coxibs and are beyond the scope of this discussion.

Cell membranes contain a fatty substance called phospholipid. When a degradative enzyme called phospholipase acts on phospholipid, arachidonic acid (AA) is released. Arachidonic acid is then acted on by COX (1, 2, or 3) to produce substances such as prostaglandins and thromboxanes that have direct effects on local tissues and blood clotting; under inflammatory conditions the release of these prostaglandins can lead to pain, redness and swelling (
Figure 1). The goal of NSAID therapy is to reduce the action of COX on AA and therefore limit the inflammatory response. One thing to keep in mind though, is that the presence of some COX (in particular COX1) is a good thing! COX 1 continuously allows for the production of “good” prostaglandins that help to keep the gut healthy (mucous and bicarbonate secretion) and an abundant amount of blood supply to the kidneys and other tissues. COX 2 and 3 are associated with situations where pain or disease are present and increase the pain and inflammation associated with these conditions. This is why NSAIDs that are marketed as COX2 inhibitors may provide improved patient safety, even though there are potential side effects with these medications as well.

For many of the standard NSAID agents we have known information about dosing and safety of administration. For instance, we know that at a standard dose of 2.2-4.4 mg/kg by mouth once or twice daily (1-2 grams for the average 1000 lb. horse) there are few clinical complications. However in a case series that was reported in 1995 by Cohen et al, 5 horses were managed for a condition of NSAID toxicity where ulcers developed in their large intestine (right dorsal colon). An interesting component of this series included the detail that most horses were treated with standard doses of phenylbutazone and had complications with this treatment. From this published report we learned that even at acceptable dosages (legal with many performance horse organizations) we can still have complications with NSAID administration. Complications commonly present as horses with a reduced appetite, gastric ulcers, loose stool, and changes on their blood analyses, such as low white blood cell counts and low protein levels (albumin).

In an investigation performed in 2004 Foreman et al compared the effects of flunixin meglumine (Banamine™) and ketoprofen with phenylbutazone and ketoprofen. Both flunixin meglumine and phenylbutazone were more efficacious for pain relief than ketoprofen. Interestingly, flunixin and phenylbutazone administered concurrently were not more efficacious than either alone, yet they were superior to saline and they were better than a very powerful positive control narcotic agent (meperidine), which suggests that stacking NSAIDs may provide a very high level of pain control in some settings that could be undesirable to the patient (mask pain that would prevent further injury). Phenylbutazone and ketoprofen demonstrated synergy even though phenylbutazone and flunixin meglumine were not synergistic.

More recently it was reported by Foreman that when horses were tested for the efficacy of flunixin meglumine and phenylbutazone (alone and in combination) and were compared to saline the combination of flunixin meglumine and phenylbutazone were not superior to flunixin alone.

In a report by Keegen et al the clinical efficacy of phenylbutazone was compared to the combination of phenylbutazone and flunixin meglumine administered concurrently. The model of analysis involved having horses examined for soundness while they were maintained in an exercise program. Interesting information was learned from this investigation, which confirmed that NSAIDs improved soundness in some horses, but those with significant disease were not consistently completely resolved with the combination of medications. An unfortunate fatal outcome of this investigation involved the loss of one of the horses in the combination treatment group to severe ulcerative colitis as a result of NSAID toxicity. The data generated from this investigation highlighted the fact that even at high doses NSAIDs may not completely resolve serious musculoskeletal pain and the risk of an adverse event increases when higher doses of NSAIDs are administered.

The most recent study that examined the use of high dose phenylbutazone in healthy horses revealed valuable information regarding the effects that these medications can have on equine patients. At high doses (either one agent at a high dose or stacking multiple NSAIDs together) adverse events can occur such as ulcerative colitis. Although the horses were apparently healthy in the early stages of this investigation with a good appetite and normal demeanor as early as three days after the initiation of high dose phenylbutazone administration, pathologic gastrointestinal lesions were developing. Overall, changes in blood tests showed reduction in white blood cell counts and protein (albumin) concentrations, changes in blood flow to the right dorsal colon and alteration in fatty acid production. This investigation highlighted the need for careful monitoring (clinically and with blood test analysis) of horses that receive NSAID agents.

In conclusion, it is important to recognize that NSAIDs are an important class of medication for use in equine veterinary patients, particularly those that suffer from musculoskeletal pain and inflammation. However, when used for an extended period of time, frequently, or at high doses (alone or in combination) the risk for adverse outcome exists. These adverse effects can be performance limiting in the case of gastric ulcers or can be life threatening in the case of right dorsal colitis. Therefore, when performance horses have a need for NSAID therapy it is important to have a careful veterinary examination performed to determine the source of pain. Once the lameness has been definitively diagnosed, veterinary recommendations should be carefully followed. In many cases adjunct therapy such as shoeing modification, injection of joints that may be affected with osteoarthritis and other forms of therapy should be considered to maintain maximal patient health and performance.

Take The Time to Double Check

 

 

The day was shaping up perfectly for a wonderful trip with my best friend, Lakota Breeze. As the grade began to level out toward the bottom of the pass and the odd house appeared in the distance, suddenly I felt a swinging sensation behind me. I glanced into the rear view mirror to see the trailer whipping back and forth wildly. My heart lurched. I couldn’t just jam on the brakes, but had to ease down for fear of tipping the already precarious trailer. But it was too late. By the time I got the truck stopped in the middle of the highway, the trailer was on its side horrifically.
“Oh my God. Oh no,” I yelled out. I jammed the gearshift into park and was digging for my knife as I exited the truck. With my knife open, I ran around to the back of the trailer to see my terrorized horse pulling back hard on his lead. There was blood dripping from his knees and the right side of his rump was hamburger from being dragged along the roadway in the open -designed trailer. I quickly sawed through the lead as he pulled back. I stayed right with him.
“Eaaaaaaaaasy big fella. Eaaaaaaaaaasy,” I cooed over and over, as much to calm myself. My heart was thumping wildly as my adrenaline shot sky-high. I was completely freaked out figuring I’d probably killed my best friend.
The rope now sliced, Lakota and I shot backwards as far as he needed to get away from that awful turned-over trailer. Eventually he stopped and allowed me to stroke him and survey the damage. A trail of bright blood led to our place of regrouping at the edge of the road. His knees weren’t gushing blood but were both pretty skinned up and the blood was dripping onto the pavement. I moved to his right to take in his exposed upper leg/rump area and suddenly realized I was looking at the blanket insulation. The heavy blanket had protected him from the terrible burn of the pavement. I lifted the edge of the blanket high enough to see a round darkness about ten inches wide on his whitish hair. The impact hadn’t broken his skin. What a relief!  I could not believe the trust this animal had in me. That same trust only forty-five minutes earlier had almost gotten him killed….
I hoisted the ramp back into closed position that in reality formed the back of the trailer. Then I checked and rechecked the hitch, but still didn’t trust it. I found some wire and secured it 1000% this time, knowing full well that I hadn’t done this procedure right to begin with. I had not clipped those two little ears down securely and heard that telltale snap that told me it was locked. Nor did I have a lock in the hole on the hitch that would have prevented this horrible occurrence. And I will always feel guilty about that to the end of my days.
Lakota forgave me, but I could never forgive myself.

Oh the lessons we all learn in this horse journey. They’re endless. And about the time you kind of think you’ve seen it all, yet another will appear. That is my promise to you: Curve balls forever with horses. My hard lesson was about checking and double-checking when trailering horses. I cannot stress enough how taking some time at the front-end can save a potential disaster somewhere down the road.

15 Steps to Trailering Safety

·Is the trailer safe? Sharp objects inside and out? Check the floorboards. With years and urine,
manure, and moisture, they rot. There could be a thousand pounds or more on any one board at any time. You must remove the mat to check the board. Use a nail or ice pick to check the board for dry rot.

·Good tires with correct pressure. Use a gauge. These tires support the whole rig plus your horses. Incorrect or uneven tire pressure is generally responsible for most towing problems and too low tire pressure is a frequent cause of tire failure. Check wheel lug nuts and bolts, which should be torqued before first road use. Check and re-torque on a new trailer after the first 10 miles, then 25 miles, and again at 50 miles. Check periodically thereafter that they are secure.

·Lighting and brake systems. Don’t wait for the day of the trip. Check these components well before the trip. Then you have time to fix the problem before you leave, not enroute. Don’t just wing it.

·Understand just how the hitch itself works. There are many different configurations. Learn yours thoroughly. This is your horse’s life at stake. Make sure the ball on the towing vehicle is the correct size for the trailer. This is especially important to check if you have different balls for several different trailers, or if you are using a new or borrowed trailer.

·All trailers have a safety chain or cable. A heavy chain is best and needs to be secured well at each end. Attach it properly. It saved my horse!

·Secure all the doors and windows. Double check. Don’t allow the remote possibility for a lead to get outside the trailer or a door to find its way open while traveling or otherwise. You don’t want to hear that story.

·Is the footing inside slippery? Urine and manure on a wood floor = slippery surface. Ridged rubber mats are the best insurance for good footing.

·Secure the dividers. Far too often dividers come loose. Be absolutely certain the divider is locked in place.

·When horses are loaded, make sure they are comfortably tied. They should be able to turn their head ninety degrees is the rule of thumb. In stock trailers untied horses are okay, but don’t overload or have incompatible horses together.

·If you are hauling just one horse in a two horse straight load, put the horse on the driver's side of
the trailer. If you are hauling more than one horse, put the heaviest horse on the driver's side. Roads are usually raised in the middle, so by putting the heaviest part of the load on the higher side, it will help to balance the trailer better.

·If driving a trailer is a new experience for you, practice driving the rig before you put a horse in the trailer. Know well how to park and back up before you head out on the road with a horse in tow.

·Stop often and make sure all’s well back there. Don’t load your horses, hop in, and head for
your 500-mile trip. Stop early in the trip to make sure all is well. Feel the wheel bearings for undo warmth. Hitch look good? Safety chain? Door and windows? Are the horses traveling ok? Everyone getting along?

· Remember when driving that you’ve got animals behind you. At corners and stops give them a slight brake a little ahead of the actual stop. This helps them prepare for that change in speed or direction.

·It’s a good idea to take along a cell phone with a fully charged battery (or use a car charger) or have a CB radio in case of emergency.

·Having trouble trailer loading your horse? Check out my “Trailer Loading” video. A variety of horses, trailers, and weather conditions are used to demonstrate my gentle solutions approach to helping horses accept trailers as part of life and basic horse training. Learn how to help your horse want to be in the trailer and look forward to the next adventure. Proper tying, securing the butt bar and door, backing out, driving, safety tips, and more are covered in my video, which was filmed throughout the U.S.A. Learn how to do it right and actually enjoy the process while heightening horse and trainer/handler confidence.

I won’t spend too much time discussing some of the tragic stories I’ve heard that didn’t turn out as well as mine. Rest assured, some absolutely horrible things have taken place in which horses had to be put down because of an owner’s very simple trailering negligence. My goal in writing this piece is for you to avoid such an incident. These animals trust us implicitly. They literally place their lives in our hands. Really. We owe them the certainty that we have done every single thing possible to make the trip a safe and rewarding time.

Why can fresh grass cause laminitis in horses?

 

Fresh grass is high in carbohydrates (sugars) which can cause stomach upset in grazing horses. During the process of photosynthesis, plants manufacture sugars that are either used for metabolic processes such as growth, or are stored as polysaccharides such as starch or fructan. The storage form of the sugars depends on the plant species. In certain situations, such as the warm sunny days and chilly nights that we see in the spring and the fall, the plants use fewer sugars for growth, and therefore store more as polysaccharides. This can cause problems for horses, especially when the sugars are stored as fructan, because fructan does not appear to be digested in the horse’s upper gut (where starch is digested and absorbed), but instead passes into the hindgut where it is fermented by microbes. It is this fermentation of fructan that appears to be a trigger factor for colic and/or laminitis, similar to a grain overload in horses. The overgrowth of fructan-digesting bacteria upsets the normal balance of the digestive tract and produces toxins that lead to Lamintis.  The fermentation of fiber carbohydrates in the hindgut is normal, and does not cause digestive disorders in the horse.

Other environmental conditions that can affect the amount of polysaccharide storage in plants include drought stress, duration and intensity of sunlight, salinity (salt content) of soil, and overall health of the plant. Again, some species of grass, including cool season grasses, Kentucky Bluegrass, Orchard Grass, Clover, Ryegrass, Timothy, and Fescues, tend to store sugars as fructan, while others, the warm season grasses, Bermuda Grasses, Buffalo, Carpet Grass, and Bahia Grass, tend to store sugars as starch and are less likely to cause problems.

How then do we manage pastures to minimize the risk of laminitis?

Horses that are kept on pasture year-round usually adjust to the new grass as it grows. Nature does a fairly good job of making the pasture change gradually. The problems usually occur when horses have been confined and fed a hay and grain diet during the winter, and are then abruptly turned out on the lush green pasture in the spring. Further, horses that have been kept up through the winter may overeat when turned out because of the palatability of the lush green foliage. This sudden change in the diet, especially when it includes a rapid influx of the unfamiliar fructan into the hindgut, may trigger digestive upset.
There are several ways to prevent or minimize problems when introducing horses to spring pastures. Feeding hay immediately before turn-out may help keep horses from overeating, since they are less likely to overeat on an already full stomach. Restricting grazing time will also help minimize risks. A suggested schedule is: thirty minutes of grazing once or twice a day on the first day of grazing; then increase grazing time by 5-10 minutes per day until the horses are grazing 4-6 hours per day total. At this point, they have adapted to the green grass.

Some True or False  

  ·         Founder can happen after feeding your horse too much fresh green grass.  TRUE.

  ·         Grasses produce fructans after photosynthesis, which is dependant on sunlight. The sugar levels are NOT increased by rain or dry weather. True

  ·         Grasses produce fructans when stressed, which can be the result of a drought, frost or rapid growth during intense sunlight (especially after rain.) True

  • Regarding horse feeding, sugar levels are only high in spring and fall or when the grass is lush and growing rapidly.  False
  • Grazing horses are safe in pasture that is not fertilized or maintained. False Long grass tends to accumulate fructans. 
  • Overweight and insulin-resistant horses are the most susceptible to founder or laminitis. True 
  • These horses can also develop a mechanical form of laminitis from excess pressure on their laminar attachments.  True  
  • Hay is safe: FALSE. Hay can contain up to 30% fructan, depending on the conditions when the hay was cut. When horse feeding, steam all your hay for founder prone horses, to reduce carbohydrate/ fructan levels.

·         Safe horse grazing time: Turn your founder prone horse out late at night when the fructans are at there lowest levels, and kept in a stall or a dry lot during the day when levels are high.  Also limit grazing during drought or cool temperatures when pastures are stressed.  Over grazed pastures which are nipped down close are very high in the fructans and also should be avoided. 
You should start the horse out grazing for 15 mins and increase by 15 mins each day for a week and then increase gradually to 12 hours or full day if conditions are good


Sarcoid Treatment The Mosdt Common Tumor In Horses

 

A Texas veterinarian is taking a novel approach to sarcoid treatment, removing portions of the tumors, freezing the tissue in liquid nitrogen and implanting it in the same horse’s body.

“This is basically a very archaic viral vaccination attempt,” says Dr. Benjamin Espy, a private practitioner who says the technique has been successful in 12 of 15 documented cases so far. “We are trying to get the body to recognize the sarcoid as foreign and mount its own response. This is an autologous vaccine, meaning it’s made from the same animal you give it to - a very common technique in other livestock species.”

Sarcoids, the most-common skin tumor of horses, are believed to be caused by the bovine papilloma virus. They can be treated with chemotherapy drugs, such as cisplatin, or removed surgically or with lasers. However, Dr. Espy says, if any trace of a growth remains, the sarcoids will return.

“If you take off a huge sarcoid and leave behind even a tiny portion by accident, there might be five, six or 10 billion virus particles in it, and the sarcoid will come back, possibly even worse because once they’ve been significantly disturbed, sarcoids can become very angry.”

An injectable sarcoid vaccine is under development, he says, but studies on its efficacy have been controversial.

Dr. Espy specializes in equine reproductive work (theriogenology), but several challenging sarcoid cases associated with equine genitalia have been brought to his practice over the years, which sent him looking for better ways of treating the tumors.

“For instance,” he says, “I had a stallion referred to me with a huge sarcoid on his sheath. There is only so much you can cut away in that area.”

For his technique, Dr. Espy takes several pencil-eraser-sized samples off the surface of the tumor and freezes them by immersing them in liquid nitrogen to kill the virus. Once the sections have thawed, Espy implants them along the crest of the neck.

“I choose the crest because the skin is thin and the area relatively immobile so it heals quickly and, if there is a scar or white hair accumulation, the mane will cover it.”

So far, says Dr. Espy, the technique has been as or more successful than conventional sarcoid treatments he has tried. The tumors typically regress between 90 and 120 days after treatment, but some have taken as long as 180 days to subside. None of the horses has had a recurrence, Dr. Espy says. The horse he has followed the longest is still sarcoid-free five years later.

Dr. Espy says after presenting a paper on the technique at the 2008 American Association of Equine Practitioners Convention, he was approached by several veterinarians who recalled a similar discussion at the 1975 convention in Nevada.

“It’s logical, so I’m sure I’m not the first person who thought of it,” he says, adding that his main goal was sharing information about an effective treatment. “I’m a repro guy, I’ll leave it up to the dermatologists and pathologists to figure out and write the paper on exactly why this works, but I’ve seen that it does.”

 


 

"Heaves” & Respiratory Health

SmartPak strongly encourages you to consult your veterinarian regarding specific questions about your horse's health. This information is not intended to diagnose or treat any disease, and is purely educational.

Brief Description

Recurrent Airway Obstruction (RAO), commonly referred to as “heaves”, is defined as episodes of obstructive lower airway disease in horses, triggered by exposure to hay and bedding. Signs include:

  • Coughing
  • Labored breathing
  • Flared nostrils at rest
  • Nasal discharge
  • Depression
  • Elevated respiratory rate at rest
  • Exercise intolerance or poor performance
  • “Heave line” (abnormal abdominal muscle development caused by coughing and labored breathing)

Supplements that May Lend Support

There is good evidence that some herbal supplements are beneficial to horses with “heaves”. Because the condition often occurs in older horses and places them under additional oxidative stress, antioxidants are recommended. Vitamin C in particular is being investigated for its role in neutralizing the free radicals associated with “heaves”.

Possible Diagnostic Tests

“Heaves” can usually be diagnosed based on the horse’s medical history and a physical examination. However, additional tests to rule out other conditions or monitor the horse’s response to treatment may be needed. These include:

  • Bloodwork
  • Endoscopy
  • Bronchoalveolar lavage (BAL)
  • Blood gas measurement
  • Chest x-rays
  • Lung biopsy
  • Lung function tests

Prescription Medications Available

Corticosteroids such as dexamethasone and prednisone are used to reduce airway inflammation, while bronchodilators such as Ventipulmin® (clenbuterol) are used to relieve airway obstruction.

Other Management Suggestions

Diet

Dust in hay is one of the worst offenders to a horse with “heaves”, so replacing hay with another fiber source such as a complete feed is often recommended. Soaked hay or hay cubes are other alternatives.

Housing

For horses with “heaves” that live inside, good ventilation is imperative, especially in the winter when most barns are closed up. If they must be stalled, dust-free bedding should be used - straw is a particularly poor type of bedding for these horses. Ideally, horses with “heaves” should be turned out as much as possible. Horses with “heaves” may be exercised, but only as much as their condition allows.

 

Questions to Ask Your Veterinarian

  • How long will my horse have to be on steroids and bronchodilators?
  • Why is it called RAO and not COPD anymore?
  • Can I continue to ride and show my horse if he has “heaves”?

 

They Don’t Call It "Heaves" Anymore

November 2007

At the International Workshop on Equine Chronic Airway Disease in 2000, a group of investigators eliminated the term COPD (chronic obstructive pulmonary disease) in favor of RAO (recurrent airway obstruction). This was done to indicate that this respiratory condition is not the same in horses as it is in humans.

RAO is defined as episodes of obstructive lower airway disease triggered by exposure to hay and bedding and characterized by difficulty breathing, severe airway inflammation, a large number of neutrophils (white blood cells), airway hyper-reactivity, and reversibility with bronchodilator treatment.

It typically develops in horses seven years of age or older that have spent a considerable period of their lives in a stable where they are fed hay. The signs of RAO include:

  • Coughing (including coughing up mucus)
  • Labored breathing
  • Flared nostrils at rest
  • Nasal discharge
  • Depression
  • Elevated respiratory rate at rest
  • Exercise intolerance or poor performance
  • Increased movement of abdomen during breathing (causing a "heave line")

RAO can usually be diagnosed based on the history and physical examination, although additional tests may be needed to rule out other conditions or to follow the horse’s response to treatment. These tests may include complete blood count (CBC) and routine chemistry, blood gas measurement, endoscopy, chest x-rays, bronchoalveolar lavage (BAL), lung biopsy and lung function tests.

While there is no cure for RAO, it can be successfully managed by reducing the horse’s exposure to organic dust and treating episodes of airway obstruction. This involves a four-pronged approach: 1) diet, 2) environment, 3) prescription medications and 4) supplements.

The single most important thing an owner can do is remove hay completely from the diet and replace it with another source of fiber. If this is not practical, then hay should be soaked for two hours before feeding. The next most important management change is to keep the horse outside 24/7. If this, too, is not practical, then the horse should be turned out as much as possible, especially when stalls are being cleaned or aisles are being swept. If the horse must be kept in a stall, straw should not be used for bedding. Instead, specially treated wood shavings, shredded paper or cardboard, peat moss, or other low-dust material should be used.

At this time, two categories of prescription medications are used to manage episodes of RAO: corticosteroids, which reduce airway inflammation, and bronchodilators, which relieve airway obstruction. Corticosteroids include dexamethasone and prednisolone or the newer beclomethasone or fluticasone. The most common bronchodilators used are in the beta-adrenergic agonist family and include clenbuterol and albuterol. While some of these medications can be given intravenously, intramuscularly, or orally, some can be given via specially made equine inhalers. This method deposits the medication exactly where it is needed, and avoids the side effects seen when medications must travel through the GI system or bloodstream to get to the site of action.

Research is ongoing as to the benefit of supplements in horses with RAO. University of Vienna researchers reported that a botanical preparation combining the extracts of several medicinal herbs seemed to be beneficial to horses with "heaves." In addition, RAO may place horses under oxidative stress, so antioxidant supplementation may be helpful to these horses. Supplementation with Vitamin C (ascorbic acid) in particular is being investigated for its role in neutralizing these reactive oxygen species.

Spring Check List

 

Spring is coming and it’s time to get back in the saddle.  If you are like most folks you feed, hay, make sure they have water, and get back in to the warmth of the house through the cold winter months.   If that sounds familiar here is a check list you might want to use to get ready for spring riding.

 

·         Check your horse over closely and make sure he has come through the winter in good condition.  If he is thin get out the wormer and grain for a little special care.  If he is fat you might want to limit his hay intake.   They only need extra hay to maintain weight when the temperature dips below about 15 degrees.  Watch those older geldings as the spring grass comes you may need to limit there grass time to help prevent the chance of founder.

·         Check for any sores, cuts or cockle burrs in coat or mane.  Start to treat any wounds and get into a grooming routine to get that mane and tail back in show shape.   A good brisk brushing at the dock of the tail will help promote growth and shine.

·         Clip bridle paths if you do.  They maybe 3 or 4 inches long after the winter.

·         Check your tack.  Saddles and bridles should be checked for signs of wear or damage.  Bits should be cleaned, and pads and blankets given a good cleaning.  Don’t forget skid boots or other protective equipment.

·         Do some refresher ground work a couple of days before you ride, to remind your horse who is the leader.

·          Spring is a good time to worm and vaccinate your horses.  Evaluate which diseases are prevalent in your region and talk with your vet to see if you can eliminate or rotate vaccinations for some diseases.  You are really just wasting money when you blindly vaccinate for everything.   Don’t forget to check areas where you haul, or plan to vacation with your horse.  There might be something extra you want to add if traveling.    

·         As the days get longer the hair will start to slip so get out the shedding blade to help your horse along.

·         Call and get on your farriers’ list for shoes or a trim.     

·         Gather a list of events, and shows you want to attend and get your name on the calendar at work for time off. 

 

These should get you on your way to a safe happy spring.  Now get out there and ride.

 


 

 What Exactly Is A Barefoot Trim

By Tom Moates, with contributions from Kristin Syverson

 

In theory, a “barefoot trim” gives a domestic horse’s hoof the same shape as a wild horse’s hoof. Supporters of the barefoot trim believe that if it happens in nature, it must be the best thing for the horse. So, it would be reasonable to associate a ‘barefoot trim’ with ‘natural.’

This ‘natural’ design is based largely on a study of mustang hoof wear in some specific western North American environments. Sometimes, you will also hear a barefoot trim referred to as a “mustang trim” for this reason.

Traditionally, farriers have been responsible for trimming both shod horses’ hooves and barefoot horses’ hooves. Fans of the barefoot trim, however, suggest that a farrier trims every hoof as if it will eventually have a shoe on it and that a ‘barefoot’ horse requires something else entirely. The ‘barefoot trim’ is actually quite different than the trim a shod horse receives.

Traditional Trim

  • Heels longer than barefoot trim
  • Bottom of hoof edge rasped sharp
  • The toe is left longer and sharper than barefoot trim

Barefoot Trim

  • More petite look from taking off more heel
  • All flare removed from the sides
  • “Breakover” in the toe of the front feet

The breakover is where the front third of the hoof of the front feet is angled or beveled, eliminating the sharp long toe. This arrangement is said to provide a more natural pivot point in the step, so the flex and mechanics to the foot and leg structures are more natural and better for the horse.

It also is generally explained in barefoot-trimming literature that this trim should ensure a heel-first landing, placing the bulk of the weight landing onto the heel, which may not always be the case in a more traditional trim where toe-first landings are most likely. Horses with barefoot trims are thought to have a reduced risk of injury, an overall proper balance of motion and better performance.

The Vet’s View
“There’s nothing wrong with a horse going barefoot.” says Dr. Tracy A. Turner, of Anoka Equine Veterinary Services in Elk River, Minnesota. Dr. Turner, whose specialty is equine lameness, worked as a farrier before entering veterinary medicine and published the now-classic article, “The Art and Frustration of Hoof Balance,” in the American Farrier’s Journal.

“If your horses don’t need shoes, don’t put shoes on them. I’d choose to have a horse go barefoot over being shod in general.”

On the topic of barefoot trims, however, Dr. Turner has some words of caution.

“Some are really radical,” he says. “My rules of thumb are: Anything that draws blood can’t be good. Anything that leaves your horse lame afterward can’t be good.”

His professional advice comes from personal experience. He has witnessed instances where radical and bloody trims were performed on horses’ feet by self-professed barefoot trimmers in the name of healing troubled hooves, which had sad and ultimately fatal consequences. He stresses, however, that a good trim is a good trim, regardless of who does it – farrier, trimmer or horse owner.


 

Core Vaccines

Spring heralds more riding and transport, so schedule your horse's annual spring veterinary checkup. (For more information see article #11398 at TheHorse.com.) Your veterinarian will administer "core vaccines," which are those considered important for every horse to have annually, regardless of geographical location or athletic use.

Vaccine Timeline for the Adult Horse

DEC/JAN/FEB: During the winter months, not much needs to be considered in the way of vaccinations unless a horse will be traveling to an area with diseases for which he would be at high risk and has not yet been immunized.

MAR/APR/MAY: Administer spring immunizations during these months in order to have vaccines on board in advance of warming weather and an active mosquito season. Your horse should receive, at the very least, Eastern and Western equine encephalomyelitis (EEE and WEE), West Nile virus (WNV), tetanus, and rabies vaccines (first three are spread via mosquitoes). Other immunizations commonly given this time of year are influenza and herpesvirus vaccines. In high-risk areas or situations, your horse might also be immunized against strangles, Potomac horse fever (PHF), or botulism. In breeding situations where a horse is likely to be exposed to equine viral arteritis (EVA), this vaccine would also be included.

By the last month of gestation, the pregnant broodmare should be toward the end of her series of primary immunizations or boosters against all "core" diseases and those specific to your general area for which she's at high risk.

JUNE/JULY/AUG: In the summer months you'll want to make sure your horse is protected against all the necessary insect-related diseases for which there are vaccinations.

SEPT/OCT/NOV: In the autumn months preparations are under way for winter. This is the time of year your horse should be well-protected against respiratory viruses, specifically influenza and the respiratory form of herpesvirus (rhinopneumonitis). These are usually incorporated into the vaccine program at the time of the fall veterinary visit. Boosters can be given at this time for WNV, EEE, and WEE in areas with mosquito seasons that extend into winter months.

The AAEP and the American Veterinary Medical Association (AVMA) describe core vaccines as those "that protect from diseases that are endemic (prevalent with a high rate of occurrence) to a region, those with potential public health significance, required by law, virulent or highly infectious, and/or those posing a risk of severe disease." These include: tetanus, West Nile virus (WNV), Eastern and Western encephalomyelitis (EEE and WEE), and rabies.

TETANUS Horses spend a lot of time around dirt/manure, so they are at particular risk for contamination of even the smallest wound with Clostridium tetani spores. An annual booster of tetanus toxoid in the spring is recommended.

Debra Sellon, DVM, PhD, Dipl. ACVIM, a professor of equine medicine at Washington State University, suggests, "The tetanus toxoid is inexpensive and safe, and the disease is highly fatal. Therefore, I always recommend a booster tetanus toxoid injection in horses with wounds or with plans to undergo surgery if it has been more than six months since that horse received its last booster injection."

WEST NILE VIRUS This disease, which causes potentially fatal neurologic illness and is endemic in the lower 48 states, is carried by birds and transmitted by mosquitoes to horses. Luckily, there are three vaccines against WNV--all are safe and have demonstrated good efficacy. Horses should receive an annual booster following the initial vaccine series.

Keep in mind the timing of your annual boosters, making sure the horse is protected during mosquito season. In warmer climes where mosquitoes abound year-round, it might be necessary to administer boosters twice a year, depending on the vaccine product. Scollay says if your veterinarian recommends vaccinating twice yearly, "it might be prudent to consider vaccinating say, April 1 and Aug. 1, to enhance immunity during the period of high risk for exposure, instead of at a rigid six-month interval."

EASTERN AND WESTERN EQUINE ENCEPHALOMYELITIS Encephalomyelitis (or encephalitis) virus, which causes neurologic disease, also is carried by birds and transmitted by mosquitoes. The vaccination strategy for EEE and WEE is comparable to WNV--once or twice annual boosters, depending on length of mosquito season, following an initial priming series. Horses living in states directly bordering Mexico might also receive an annual booster for Venezuelan equine encephalomyelitis (VEE).

RABIES Scollay says, "Rabies is a fatal neurologic disease of warm-blooded animals; that means horses and humans." Wild animals such as bats, skunks, foxes, or raccoons can bite a horse and pass this virus without anyone being aware. Given that humans are constantly inserting their hands into horses' mouths when placing a bit, checking age, floating teeth, or administering dewormers and paste medications, Scollay asks, "Why would you risk contracting a fatal disease from routine contact with a horse, especially when the disease can be effectively prevented?"

Rabies vaccine is labeled to be given once a year, but Scollay says if you have concerns about a specific horse's immunity, it would be appropriate to consider a series of two vaccinations.

Risk-Based Vaccines

Vaccines against certain diseases are given based on anticipated degree of risk.

INFLUENZA VIRUS Horses that travel or encounter horses that have been traveling are at an increased risk of exposure to equine influenza virus. The 2007 Australian epidemic, in which thousands of unvaccinated horses were exposed to flu, displayed how readily the disease could spread. There are many effective equine flu vaccines, and a horse should receive two or more boosters a year (depending on which product is used), usually in the spring and fall, following the initial series of three injections and/or intranasal (IN) administration of certain products.

HERPESVIRUS OR RHINOPNEUMONITIS Equine herpesvirus (EHV-1 and EHV-4) can cause respiratory problems (this disease expression is known as rhinopneumonitis). Rhino is spread through respiratory secretions--on shared objects or airborne. Cough, runny nose, or fever can be readily apparent, but EHV can be latent (hidden) in the horse, meaning it sits in the lymphatic tissue without producing any proteins and, therefore, the horse does not "respond" to it. Stressors such as transport, weaning, castration, mixing of horses, or foaling can reactivate the virus, which the asymptomatic horse sheds in respiratory secretions. EHV-4 causes mostly respiratory disease, whereas EHV-1 can cause respiratory disease, abortion, or neurologic disease.

Scollay says research has shown EHV vaccination programs help reduce clinical disease and the period of viral shedding in adult horses. "It is reasonable to assume that many of the horses that experience these benefits were initially infected as foals," she notes. "This is an important 'herd health' concept--that by minimizing clinical disease and viral shedding in horses that respond well to vaccination, you are also providing increased protection to horses in the same population that did not, for whatever reason, develop a good immune response to a vaccination."

Vaccination can prevent the return of disease, suppress virus so it remains latent, and stop shedding in nasal secretions, limiting transmission to naïve horses.

STRANGLES Available vaccines do not protect entirely against Streptococcus equi-caused disease, and there are controversies surrounding its use in some animals. Sellon weighs in: "Strangles IN vaccine is used in horses at risk of exposure to strangles. The exception to this is horses with very high previous, especially if recent, exposure to strangles. Most experts agree that vaccination of horses with either IM (intramuscular) or IN vaccines, if they have a pre-existing high titer to the bacterial organism, is associated with an increased risk of adverse effects. I recommend IM strangles vaccine for broodmares in the last 30 to 60 days of gestation if they or their foals are at risk of exposure.

All strangles vaccines have been associated with immune-mediated reactions, such as vasculitis (inflammation of blood vessels) and myositis (inflammation of muscles). The IN vaccine, which is (made with) modified-live bacteria, may cause abscesses, rarely. The IM vaccine often causes soreness, swelling, or potential abscesses at the vaccination site. Base your decision to vaccinate for strangles on assessment of the potential risks (farm history, lots of horse traffic on and off farm) and benefits.

Consider diagnostic testing to determine if the horse is harboring S. equi before vaccinating. (For more information see article #10688 at TheHorse.com.) Following a primary series, veterinarians administer strangles vaccines once or twice annually in high-risk areas.

EQUINE VIRAL ARTERITIS This disease is encountered most commonly in the semen of an infected carrier stallion, yet it can be passed from horse to horse in respiratory secretions. Most times this vaccine is used to protect breeding stallions, mares with planned breeding to a known infected stallion, and nonbreeding horses in the event of an outbreak. Pregnant mares should not receive the EVA vaccine. Before vaccinating, you can screen a horse for previous exposure to EVA with a blood test. Vaccinating for EVA might also preclude a horse's entry into some countries, as it is difficult to determine natural versus vaccine titers. (For more information see article #10215 at TheHorse.com.)

POTOMAC HORSE FEVER (PHF) This is a diarrheal disease (and occasional cause of abortion) caused by the organism Neorickettsia risticii. Its effect on horses follows a seasonal pattern, usually between late spring and the fall during hot weather (vaccinate prior to insect hatching and warm weather). Horses are infected by ingesting infected insects derived from aquatic environments. Current vaccines do not have challenge information based on this natural route of infection, but, instead, are based on a transmission method that was suspected and now has been disproven (ticks, so tests to determine vaccine efficacy were done with blood challenge).

ANTHRAX This is a fatal disease caused by Bacillus anthracis, occurring in specific geographical locations where the spores remain in the soil for decades. This vaccine is usually only administered to pastured horses in high-risk areas. A primary series is followed by an annual booster.

BOTULISM This fatal neurotoxic disease disease is caused by Clostridium botulinum. A vaccine is available for C. botulinum type B, which is particularly useful to protect foals against shaker foal syndrome that have acquired botulism through ingestion of the spores.

Sellon comments, "Botulism should be included in broodmare vaccinations if the horses reside or will travel to areas where type B botulism is known to occur. This generally means Kentucky and the mid- Atlantic region of the eastern United States."

Pregnant mares in high-risk areas should be receive a primary series at least four to six weeks prior to foaling to ensure transfer in colostral antibodies for the foal. Foals should also receive this vaccine series in high-risk areas. Vaccinate adult horses in these areas based on a veterinarian's recommendation.

ROTAVIRUS In the case of the diarrheal disease rotavirus, vaccinate the mare to protect the foal, especially if there have been previous problems with this disease on the farm or in the area. Sellon counsels, "All breeding operations, large and small, should have in place reasonable biosecurity plans to decrease the chance of accidental introduction of the disease on the premises. Vaccination for rotavirus should never be considered as a replacement for this type of husbandry."

Administer a three-vaccine series to a pregnant mare by the last month prior to foaling. This way a foal receives colostral antibodies that provide resistance to rotavirus for the first 30 to 60 days. This vaccine is not necessary for other adult horses.

Foal Vaccine Program

A foal's first-year immunizations begin as a series of two to three injections (depending on the product), followed by boosters once or twice a year. Most foals are born in the spring and will not receive EEE, WEE, WNV, and tetanus immunizations until 4 or 5 months of age or later. Don't start flu and rhino until 6 to 9 months of age, depending on the mare's vaccination history.

Scollay explains that foal vaccination timing is based on maternal antibody interference. "While the antibodies in the mare's colostrum provide a foal with early protection against infectious diseases," she says, "those same antibodies can also inhibit the foal's own immune system from 'learning' from a vaccine and developing its own immunity to disease. If the mare was vaccinated late in pregnancy, the foal's vaccinations should begin later than if the mare was not vaccinated late in pregnancy. If you don't know the mare's vaccination status, you must assume she was both vaccinated and unvaccinated."

How Many Vaccines At Once?

Many horses can receive multiple vaccines at one time and have no adverse reactions, particularly if using separate injections rather than multivalent products, but not all horses fare well in this scenario.

Scollay gives the vaccinations in two sets, 10 to 14 days apart. She says, "I don't know if this benefits in terms of developing better immunity, but I do think the horses are more comfortable with less localized muscle soreness and general 'punkishness.' "

Determine how your horse fares with individual vaccine products, then try to minimize future adverse reactions.

Take-Home Message

Ensure that your horse receives his core vaccines annually, along with any other vaccines against diseases for which there is a high risk in your area, and make sure he gets his boosters. Collaborate with your veterinarian to tailor the best strategy for your horse, based on exposure and risk.


Annual Vaccinations From A Holistic Veiw
Harmany Equine Clinic, Ltd.


Article summary
The vaccine issue is a complex one. There is not one perfect answer as to whether to vaccinate, or what to use. It is clear that annual vaccines can have negative effects on our animals, yet many people board their horses in barns where they are required to vaccinate. This lengthy article covers some of the latest thoughts about vaccinating, the use of titers and alternatives to regular vaccination.

Annual Vaccinations

Each spring we begin thinking about vaccinations. The vaccine issue is actually a complex one and needs the active participation of the owner to help make the best decisions for the horse. The days of just vaccinating all nd veterinary practices.

Definitions
Generically the process of protecting against an infectious disease by "priming" the immune system with material, the immunogen, designed to stimulate an immune response to the infectious agent is known as immunization (www. answers.com). Vaccination is used when the immunogen is itself a living infectious agent, normally either a closely related bacterial species (as with smallpox and cowpox), or by using a strain weakened by some process. Technically immunization is different from vaccination in that vaccination uses a viable infecting agent (i.e., it can make the individual sick, ex: a live virus vaccine) while immunization does not use a viable agent (killed virus vaccine, or even just part of a virus-recombinant vaccine). In everyday horse language, we use the words interchangeably.
Either form of priming the immune system can produce a measurable "antibody" in the blood. A test for how much of this antibody is present is called a titer or serologic test. The measure of a titer response in the blood is one indication of how well a horse might be protected against a disease. Little research has been done to determine the exact amount of a titer needed. However, most vaccines are sold based on the fact that they produce a measurable titer in the blood, rather than that they are proven to protect a horse against an actual disease challenge.

Titers are a useful indicator, but not the perfect answer to determining the protection status of a horse. The reason they are not perfect is that the immune system is very complex and there are many more places inside the body where the vaccine can protect other than in the blood. Cells inside the body can also have immune responses, called cellular immunity. We cannot measure this from the outside easily. So, it is possible to have a horse with a low blood titer, that is actually well protected. Some university vaccine researchers feel that if any titer is present at all, there will be protection at the cellular level. Also they feel that even animals with no titer may be well protected. Titers are, however, the main way available to the horse owner and veterinarian to get an indication of how well your horse could be protected.

Many veterinarians refuse to check titers thinking they are invalid, and many more just do not know how to interpret the results or even to which laboratories to send the samples. The American Veterinary Medical Association (AVMA, www.avma.org, type in vaccine) does acknowledge that titers can be a measure to determine a need to for revaccination, but does caution that the data is unclear. The best way to approach titers is to use the results as a guide and take all the factors discussed below into account.

 

It is wise to give some thought to your vaccination schedule, and to not just vaccinate blindly for every possible disease. For some it may be time to make a change in your schedule. Vaccines are stressful to the immune system. Vaccines should not be given to animals that are in any way ill, whether the problem is a skin condition or a serious internal disease. The package insert in vaccines states that only healthy animals should be vaccinated. Remember that people used to be vaccinated only a few times as young children, then as adults only for flu or if the person is going to a foreign country. Now the current vaccine program for children has gotten as excessive as it has for the horses.

Vaccination must be done at the level of comfort of the animal's caretaker. If you feel uncomfortable changing the vaccination program, keep examining the issues. More evidence is surfacing that over-vaccination is a problem and should not be done, but until sound research tells us exactly what to do, the decisions are up to the individual.

Holistic veterinarians are trained to look for subtle signs of disease and have more tools in their medicine chest to treat these chronic problems. Many holistic vets, including myself, find a variety of illnesses related to over-vaccination. Some of these are serious and life-threatening, while others are annoying. Reactions can occur up to about two months after a vaccination. Horses often become more susceptible to other diseases if their immune system is in poor shape after excessive vaccination. So, it is best to look at the vaccination issue with the information below and make decisions based on thinking rather than a rote program.

Annual vaccinations, practical applications
The key to a successful program is to examine each disease and vaccination based on the risk of the disease versus the risk and benefit of the vaccine. For example, flu in the horse is not life-threatening, is easy to treat with alternative medicine and can be treated fairly well with conventional medicine (remember, it is a viral disease and antibiotics do not treat viruses). The injectable flu vaccine was proven to not work in a large study and in my opinion seems to be one of the most stressful vaccines for the horse. The intranasal vaccine does work, and should last for a long time, though there is no research to support its effects past 6 months to one year. Since the injectable vaccine is fairly ineffective, stressful to the horse (high risk) and disease is not serious (unless you just have to make that show!), the benefit of the vaccine is very low.
Rabies is the opposite in all ways. The disease is life-threatening and very serious and the vaccine is highly effective. However, since the vaccine is so effective, only a few shots in the lifetime of the horse will be protective for most horses. Extensive research in humans has shown that fairly low titers are very protective. Most horses in my practice have titers thousands of times higher than the protective level needed in humans. And, though no research indicates exactly what titer is needed by an equine, it is safe to say that the high titers seen in horses should be protective.
Potomac Horse Fever vaccines fall somewhere in the middle when analyzed. The vaccine has not been shown to have complete protection. If it were extremely effective, it would have eliminated the disease, since currently it is safe to say that most horses living along the Potomac River are vaccinated, yet the disease appears each year and horses still can die from it. However, if your barn is along a major river basin (high risk), and cases are seen each year in your immediate area, vaccination may be a wise thing to try, recognizing that it is not a perfect vaccine. However, if you are not along a river basin (low risk) and the veterinary practices in your immediate area do not see many cases, then it is a vaccine to skip. The vaccine does not appear to be as hard on the horses as some others. Titers are available and often are seen at a protective level without constant revaccination.
The Rhinopneumonitis vaccine is another vaccine where the disease is a low-risk upper respiratory infection. The vaccine is poorly effective; as such many vets recommend it every couple of months. It does seem to cause many side effects (high risk for the horse). The viral infection is easy to treat with alternative medicines such as homeopathy and Chinese herbs, but often is so mild it requires little treatment. The dangerous neurological form of the disease is not covered by any vaccine. Horses vaccinated against the respiratory form may actually be more susceptible to the neurological form if it passes through a barn. The abortion form of the disease does have a vaccine, but it needs to be given every few months, and is probably not needed in mares that foal at home rather than at a large facility with lots of chance for exposure. Titers can be taken, though they tend to be fairly low.
Tetanus is a high-risk disease with no titer test available. It also seems to be a very safe vaccine (low risk). In the early 1990s when a titer test was available, the vaccine appeared to be very effective with high titers for long periods of time without revaccination. This may be a vaccine to keep in the program, but it is also probably one that could be done every few years instead of yearly.
Strangles is a highly contagious disease, but actually is not usually life-threatening if the animal is cared for well, and is fairly easy to treat with both alternative and western medicine. The healthier the horse's immune system is, the less likely it is to get sick, and the easier it is to recover. Once the long-lived bacteria get onto a premise, it is a disease that can affect new horses coming onto the property. Most horses who have had the disease are immune for life. Since it is so contagious, barns with active cases are usually quarantined to prevent the spread of the disease. Strangles is an messy disease, the horse does feel sick and they do get abscesses that drain. However, it is a low risk disease as far as the long-term health of the horse goes. The vaccine seems to cause more problems that any other vaccine, so is high risk vaccine. Titers are available. An outbreak of this disease is one of the best places to use the homeopathic nosodes discussed later in this paper.
Western Encephalitis does not exist in the east, and Eastern Encephalitis not in the west. However, you cannot buy a vaccine for just one of these diseases. The disease is seen mostly in warm parts of the country with a large mosquito population. Occasionally it is seen in other parts of the country, but in general many areas of the country are at a low risk for the disease. In a high risk area, it may be advisable to vaccinate or at least check titers, since the disease can be life-threatening (high risk disease). The vaccine seems to be moderately safe, but can cause some reactions. Titers are available.

West Nile virus is the new disease on the block. It seems to be moving across the country leaving behind a low level of disease. However, we do not yet know what the disease patterns are or will be from year to year. It is a high risk disease (serious if your horse gets it), and possibly a problematic vaccine (there are quite a few reactions to some of the vaccines). So, vaccinating is not without some risk, and it is important to make the decision for each horse based on its health history. The young, strong animals are least susceptible. Titers are available and it appears that the vaccine and possibly some natural immunity are fairly effective as many titer levels are good.
Time of year for vaccinating
When making decisions about vaccination, study the disease. As an example, it is pointless to vaccinate for a mosquito-carried disease in October if you live in New England, or anywhere in the northern 2/3 of the country where there are no mosquitoes in the winter. The diseases that are carried by mosquitoes include Eastern and Western Encephalitis and West Nile Virus. All of these diseases occur primarily when the mosquito population builds up to high level in the late summer and fall. Cases are rare earlier in the year. Potomac Horse fever also occurs in July through October. So, for these late summer diseases it would be better to vaccinate in May for maximum protection rather than in February or March when it is convenient.
The best way to get maximum benefit from vaccination is to spread the shots out rather than overload the whole system with everything at once. If the immune system is at all weak, multiple vaccines given the same day may not be very effective. Rabies and tetanus are year-around diseases, so these could be given at any time of the year. Save the late spring for diseases of the summer. Then the horse has maximum protection during the peak of the disease and there is no need to vaccinate twice a year for vaccines that may not be as effective. Twice a year vaccination adds more stress to the immune system.

Alternatives to vaccination
There are several alternatives to the conventional schedule. One is to check titers and just vaccinate for those diseases that have low levels of antibodies present. Another is to improve the health of the horse's immune system to help prevent susceptibility to disease, or to help the horse cope with the vaccine better. Homeopathic nosodes are another possible way to help the immune system.
When using with a regular vaccine, some of the side effects can be prevented by giving the homeopathic remedy Ledum Pal. 30X or 30C (6-8 tablets once a day for three days following a vaccination). This treatment can prevent reactions such as a stiff neck and lethargy, as well as some of the more severe reactions seen. Ledum can also help prevent some of the long-term negative effects of vaccines, though nothing can prevent all problems.
It is important to improve the overall heath of your horse's immune system with good nutrition and immune system support. The exact details of a program can be tailored to your horse's needs with a nutritionally-oriented veterinarian as well some good research on the part of the caretaker.
Another option for vaccines is to use homeopathic nosodes, which are like a homeopathic form of a vaccine. The nosode is made from the diseased part of the animal (such as mucous from the nose of a strangles horse), but is diluted so that it works like other homeopathic remedies. Nosodes often get used in place of vaccines. There is little research to support their use, and what has been done has not shown much promise. However, having said that, clinically there are many instances around the world where nosodes are used successfully in the prevention of disease.
It must be stated that no one can promise nosodes will prevent disease, and anyone that says that is giving false information. The correct answer is that they might work. The general conclusion in a recent discussion amongst holistic vets is that nosodes work best in the face of an out-break of a disease, but may not help much in the day-to-day long-term prevention. Regular vaccination is often not advised in the face of an outbreak, since it takes at least ten days for the vaccine to trigger the immune system. If the animal has already been exposed to the disease but does not yet have symptoms, sometimes a vaccination can make them sicker. Nosodes can be very helpful here.
The giving of any homeopathic remedy alters that body's chemical and energetic makeup. Most holistic vets are leaning way from using nosodes except in an outbreak situation. Nosodes are available for most of the common diseases, including West Nile, however they are only available through prescriptions with a holistic veterinarian. And it is best not to just give them to any horse without knowing something about the current state of health. In many cases it is better to improve health than to just throw nosodes into the horse and hope for the best.
When several generations of animals have been raised using no vaccines or only a few nosodes, the offspring become healthier and more resistant to diseases of all types.

Conclusion
There is not one perfect answer to the vaccination issue. Each and everyone must make the best, informed decision for each horse, each year. As new information comes available, read and learn everything you can. Your horse will thank you.


 

Treating Cuts and Tears

Know what actions to take if your horse gets hurt.

From our friends at eXtension

Wounds require immediate attention and first-aid treatment. The seriousness of a wound depends on the location, depth, type of cut or tear, amount of tissue damaged and type of tissue affected. Serious wounds should be treated by a veterinarian.

All cuts and tears should be cleaned thoroughly and all foreign debris removed. Apply nitrofurazone or an antiseptic ointment to the wound.

Wound Treatment

In treating your horse’s cuts and tears, follow six steps:

  1. Stop the bleeding. Blood from a cut artery spurts and is bright red. Venous blood is dull red and flows rather than spurts. Direct pressure is required for almost all cuts and tears. Pack gauze into large or deep wounds and apply pressure until the bleeding stops. Very seldom will a tourniquet be needed. Apply direct pressure on a wound with a gauze pad, using your hand or a tight bandage. If a tight bandage is used to stop the bleeding, it should be removed once the bleeding has stopped. A horse can lose up to 10 percent of its blood before the loss becomes critical. A 1,000-pound (454 kg) horse has about 50 quarts of blood. A horse can tolerate a slow blood loss, whereas rapid loss of blood can be critical.
  2. Clean the wound with warm water to remove all dirt and debris, preferably using a hose with running water. If water is not available, use a gauze pad to clean the wound. Press the gauze pad into the wound. Don’t rub or swab the wound because that will cause further tissue damage. Avoid using cotton because pieces of it will remain in the wound. The hair around the edges of the wound should be clipped or shaved.
  3. Immobilize the wound to prevent further damage. Hold the horse or place the horse in a box stall. Try to prevent the horse from chewing the wound or bandage. A neck cradle prevents chewing of most wounds. Cayenne pepper or hot pepper sauce applied to the bandage can discourage a horse from chewing. If the wound requires suturing, the veterinarian should do so within 12 to 24 hours for best results.
  4. Prevent infection. Antibiotics should be administered under the direction of a veterinarian. Wounds can be treated with a nonirritating wound dressing. Minor skin wounds can be treated with nitrofurazone.
  5. Protect the wound from dirt and other debris by applying a bandage. A bandage may decrease movement and promote faster healing of the wound. However, care must be taken when applying a bandage because if it is applied incorrectly, it can cause more damage than good.
  6. Prevent tetanus. If the horse has not been vaccinated against tetanus within the last eight to 12 months - or if you are unsure when its last tetanus vaccine was given - administer the tetanus antitoxin. Tetanus toxoid should be given every eight to 12 months.


Winter Health Care

By Joyce Fox

 

If your horse is healthy, wormed, has good hay, water, and a place to get out of the wind, you should bring him though the winter in pretty good shape.  Mother Nature has prepared your horse with everything he needs to survive the cold weather with very little problems.  Your horse is really quite comfortable in the colder months as his temperature is naturally hotter than a human.   But, with the cold weather your horse may need a little help, and you may feel the urge to do more than is really necessary or healthy for your horse.  A water source for your horse is very important and your horses can be very resourceful, by licking the ice to melt a hole, pawing the ice to break it, or eating snow.   I am not recommending you let your horse fend for himself but, if its 5 degrees you are chopping ice and they don’t seem to be drinking from the hole go searching for a small dished out place about the size of your fist.  That will be where they are drinking and you can chop the hole there.    If you choose to grain your horse they do quite well on grain but the hay consumption and digestion of fiber is what generates the most heat for your horse.  Worms are the biggest thief your horse deals with in the winter.  They can rob your horse of vital nutrients energy and ultimately heat.   The problems start when we as owners become worry warts and think it is to cold or our soft spot comes out and we put them in the barn and blanket them until we get tired of messing with constantly putting the blanket back on after the horse rubs it off, repairs after the horse rips it with his teeth, or the rubbed off hair and chaffing caused by the blanket  Then we take the blanket off, leaving him to deal with the cold, or confine them in an area that is too small and dusty or becomes nothing short of a mud pit.  That is when the problems start.   It takes about 3 to 10 days for your horse to acclimate to climate changes.   So providing a free will wind break or shelter from cold rain or snow is very helpful to your horse in early winter or the very worst conditions.  But if you watch they will always choose the spot that is out of the wind and exposed to the sun when left to choose a place to relax and warm up.  I don’t like to see people who go out and ride for several hours on a warm day and get their horse hot and then don’t cool him out and let him dry before putting back out in the pasture.  Sweaty matted hair will not insulate and repel precipitation like a normal dry coat.   

 

Respiratory Problems can be caused from dust in the barn, and poor ventilation.  Horses in close quarters will spread disease quicker, because of the close contact.  Temperatures changing from cold to warm can cause infections to become more serious.   Turning out a horse who has been in the barn and is not allowed to build his winter coat can cause many problems.   Always allow the horse to acclimate to the weather change.

 

Sore Feet:  Walking around on frozen ground can cause soreness in the feet and legs. Bumps and bruises come with the rough frozen ground.   Most will heal with out much problem but a little Epsom Salt soak can ease the pain if needed.   Abscess can be helped by soaking a cotton ball in Tea Tree oil and packing it into the abscess.  It will help draw the soreness out and keep it clean.

 

Worms:  A wormy horse left alone will show a rapid decline in condition in the winter months.  Make sure to keep your de-worming schedule up to date for the winter.   Watch for loose manure, pot bellies, rubbing, and dull coat.  If you see any of this get out the wormer!

 

There are many more things that can affect your horse in the winter but with a little help from you he will be in good shape to start up the spring riding season.

 


 

Take care of – but don’t coddle – those early foals.

By The Journal’s Christine Hamilton

Breeding experts Dr. Joe Carter, D.V.M, of Oklahoma Equine Hospital, and Barbara Helland, owner of Helland Ranch in Hutchinson, Minnesota, have years of experience in the horse-breeding industry. They foal out both ranch-owned and client mares in the winter.

Here, they offer their advice on the specific management needs of early foals. What they had to say centered around four major areas of concern.

Concern No. 1: Foaling

This might sound obvious, but in cold climates never let a mare foal outside. Too often, mare owners make that mistake, either by accident or ignorance. If you’re dealing with a cold climate, Barbara says you need to have the mare in a stall. To have a foal outside is very risky for the mare and the foal. A foal could freeze to death or, at the very least, get frostbitten ears.

However, a mare doesn’t have to foal in a heated barn.

“If someone doesn’t have a training facility or a large ranch,” Barbara says, “and they’re in a part of the country where there is snow, they’ll be fine with a stall they can put a couple of heat lights in, or just a 200- to 300-watt bulb. Try to keep the stall fairly warm, with good bedding.” And make sure to be in attendance.

Once the mare foals, if you don’t have heated facilities, get the foal dried off.

Barbara points out one thing she has noticed: “Most early foals are born with long hair. Mother Nature takes care of them, especially if the mare has been outside.

“If you have a winter foal where you’ve pampered the mare and she has been under lights and didn’t get turned out, that colt will be born with smooth hair. On the other hand, if the mare has gone out daily and is used to the climate and the weather, the colt is usually born with long hair.”

Once the foal is dry, that long hair does it good.

“If the mama has had to weather it,” Barbara continues, “I think that colt will be a little more rugged in its overall strength.”

Concern No. 2: Fresh Air

“Fresh air and being outside in cold weather is less of a concern than being inside, confined with poor ventilation,” Dr. Carter says. Any barn, no matter how clean, will have ammonia buildup from urine in the stalls. Since ammonia is heavier than air, it rests close to the floor, right where foals spend a lot of time.

“High ammonia content is hard on foal lungs,” Dr. Carter continues. “Hopefully, you have a well-designed barn that’s going to allow for the ammonia buildup and smell that a closed barn will have. With a poorly designed barn, I would be even more sensitive to the fact that it could be damaging to their lungs, and fresh air is going to help them. Breathing in that ammonia can set them up for pneumonia and other respiratory problems.”

In a heated barn, you also run into moisture buildup, which creates an environment for bacteria to grow. Barbara points out that an exhaust fan can help ventilate a heated barn.

Barn dryers are another helpful piece of equipment, although more expensive than simple exhaust fans. Found commonly on pig farms, a barn dryer takes the humidity out of a barn environment by heating cold, dry air from outside and shooting that into the barn, rather than heating the old, wet air inside.

In any case, no matter how well ventilated your barn, nothing beats clean, fresh air a foal gets from being outside.

Concern No. 3: Shelter

Can young foals be outside when it’s really cold? Dr. Carter has this to say: “I think people should not anthropomorphize their horses, apply human characteristics to their animals. God designed them to run around in cold weather. You’ve got to use your common sense. If it’s going to be zero degrees with a 30 mph wind, they certainly aren’t designed to be out in that kind of weather.

“But look at your typical early spring storms. There are some blustery storms in March. Since the natural breeding cycle begins on the first of April, you could naturally see foals born in March and April, in that kind of weather. They can handle it.”

Get paid to show your horse! Enroll your foals in the Incentive Fund. When your horse wins, so does your wallet.

Just make sure early foals have shelter.

“Wind protection is the moist important thing,” Dr. Carter says. “I like farms to have a windbreak where horses can be protected from a strong north wind.”

Barbara points out that the problem with snow is often not the cold, but the physical problem of having turnout space full of drifts that a foal can’t get through.

At the Helland Ranch, Barbara makes use of an indoor arena for those snowed-in days.

“I wouldn’t suggest anyone turning foals out if it’s snowing,” Barbara says. “It lands on them, and some of it melts with the heat of their body. The foal will get severely chilled. If you have a safe lot that’s not slippery, babies will cope with the cold, as long as wind chill temperatures aren’t 10 to 20 degrees below zero.”

She adds another thing: “I know some people blanket their babies and turn them outside. I don’t suggest that at all. Mother Nature will take care of them. The more days they’re outside, the better they get acclimatized. It happens very, very quickly.”

Concern No. 4: Exercise

Breeders sometimes complain that early foals will have leg problems. That might be related to exercise – either not enough or too much. Owners can make the mistake of keeping an early foal inside too much, without exercise.

“Bone is a very dynamic organ in terms of its response to exercise,” Dr. Carter explains. When it’s not being exercised, it’s not developing as strongly – laying down more calcium, hardness, converting cartilage to bone in the growth plates – as it normally would.

“If it’s exercised, the body is recognizing work and the need to get stronger, and the bones recognize the need to get stronger, so they develop. You’ve got to get those legs stimulated to start doing what they’re supposed to do.”

That means plenty of room to run and play.

“Treat that early foal like you would any other,” Dr. Carter says. “Keep it in a stall for the first day and make sure everything is OK, then start turning him and the mare out in a small paddock.”

On the other hand, inclement winter weather is bound to hit, and that early foal will have to be kept inside for a few days. Owners can make the mistake of giving a foal too much exercise too soon after prolonged confinement.

Again, Dr. Carter explains that “there was a study that found a higher incidence of OCD lesions with foals that had been stalled for one week or longer for different maladies, such as diarrhea or pneumonia.” OCD stands for osteochondritis dissecans. It is a developmental orthopedic disease caused by a lesion in joint cartilage and/or in the bone just beneath the cartilage surface, which can eventually affect the joint action itself. It most often presents itself in younger horses, from the short yearling to 2-year-old age.

“Those foals had a higher incidence of OCD than the normal populations, and the speculation was that it was due to going from stall confinement to sudden exercise. If a foal has been rested a week or longer, the bone softens; it is that dynamic when they’re that young.

So, after confinement, if the mare and foal are turned out into a pasture, a mare typically takes off at full speed down the fence line with the baby galloping behind her.

“The chances are pretty good for that foal to ‘hit’ a soft spot on the end of its bone, thereby damaging the cartilage and the bone underneath it, creating the opportunity for an OCD lesion to start.”

Dr. Carter says the same risks probably apply to stall confinement for a prolonged bad-weather period.

“If we’ve got a foal that has been in confinement for a reason, then you work him out gradually, increase his exercise slowly. Go from the stall to a small trap or a stall with a run, and then incrementally increase his time, so he doesn’t overdo and damage those growing bones, setting himself up for OCD and other potential problems.”


Keep your horse at a healthy weight during the cold months.

By Thomas R. Lenz, D.V.M., M.S.

Temperatures between 15 and 60 degrees F are considered energy neutral for horses. This means that within that temperature range, horses don’t require extra energy or calories to stay warm or cool. However, this assumes that the wind is not blowing and the horse’s hair coat is not wet, because both conditions increase the horse’s caloric needs.

Horses instinctively know when they need extra calories to increase body temperature and maintain weight. Unfortunately, most horses are on a fixed diet and when additional calories are required to keep them warm or to maintain body weight, they are at the mercy of their owner’s ability to adjust the feed ration.

When feeding horses in cold weather, it is important to know two things:

  1. Don’t be deceived by woolly winter hair coats that can make a horse look fat. During cold weather, horses that are not receiving adequate rations first burn stored fat and then protein from muscle tissue to fuel daily activities. Initially, fat reserves stored along the ribs, crest of the neck and rump are used. Then the muscles in the neck, shoulder and hindquarters are sacrificed. So when trying to assess body condition on a winter-coated horse, run your hands over the horse’s back, hips and ribs to determine if he is losing weight. If you are uncomfortable estimating weight loss through palpation, use a weight tape to check the horse’s weight in the late fall and then weekly throughout the winter.
  2. Keep in mind that hay – not grain – is the best feed to help a horse generate body heat. The heat of digestion from five pounds of extra hay will raise the average horse’s core body temperature 1.2 degrees for nearly four hours. Forage is digested in the horse’s large intestine through bacterial fermentation, which not only provides nutrients but also generates heat. Concentrates such as corn and barley are low in fiber and are digested in the small intestine through enzyme activity, producing little heat.

Is your horse’s health important to you? AQHA’s “Your Horse’s Health” DVD gives trusted and practical advice on how to keep your horse at his best.

Winter Goals

When it’s cold, focus on providing plenty of long-stemmed hay, preferably free choice. Unlike grains, additional hay can quickly be added to a horse’s diet without risk of colic or founder.

When faced with cold weather, many horse owners tend to keep their horses’ hay intake constant while increasing the grain portion of the diet. Although grains are very calorie dense (a pound of corn contains 1,800 calories; a pound of oats contain 1,500) and work well to fatten a horse, they are low in fiber and generate little heat. However, additional grain provided in the fall will add a layer of fat that serves to insulate the horse and does help him retain heat.

Summary

Good-quality hay should be the foundation of any equine diet and the first component to be increased to generate heat or regain body condition. If a horse continues to lose weight on hay, add grain to increase the caloric supply. Remember that the sudden addition or increase of grain in a horse’s diet – especially of corn or barley – can cause colic or founder, so add grain slowly over several days.

Winter isn’t the only time of year your horse needs to be fed carefully. Learn more about your horse’s dietary needs and other important facts about your horse’s health from AQHA’s “Your Horse’s Health” DVD.

An idle horse in comfortable weather will consume roughly 3 percent of his body weight in feed every day and at least half of that should be forage.

Toward winter’s end, give your horses a thorough going-over to make sure that the cold winter months have not taken a toll on body condition. Pay particular attention to very old or young horses.

Riding In the Winter

Here are some tips for riding in the winter.  Remember your horse might be a little more frisky on a crisp clear morning, especially if its be awhile since you have ridden him.  

  • Provide More Grip: If you plan to ride, and the ground is slippery ask your farrier about shoes with pads and ice caulks or pulling shoes for the winter.

  • Adjust the Workload: When riding in the snow remember that it is harder work for the horse. Plan your time in the saddle and your speed accordingly. 

  • Slow Down: Plan to school or work at a slower pace so your horse does not sweat as much.

  • A Wet Horse Can Get Cold: Plan extra time to cool down.

  • Keep Muscles Warm: If your horse is used to being stabled and blanketed consider using a ‘rump rug’ or ‘quarter sheet’ to keep his muscles from getting chilled while riding.

  • Dress in Layers: Dress yourself in layers that can be removed easily if you get warm while working your horse.

  • Wear Safe Boots: You may want to wear warmer boots while riding in the winter. Be sure they are not so bulky as to get wedged into your stirrups. They should still slide out easily if you take a spill.

  • Prevent Snowballs: If snowballs form in hooves while you ride, give the bottom of hooves a coating of petroleum jelly.

  • Avoid Hazards: When riding out, make sure you stay away from areas where holes, branches, poles or other hazards might be hidden under the snow.

  • Warm the Bit: A frosty cold bit can be uncomfortable for your horse. Keep bridles in the house, warm the bit with your hands, or put a warm (not hot) gel pack around the bit before putting it in your horse's mouth.

  • Bring a Snack: Pack a granola bar and a vacuum flask of hot cider or chocolate to warm you up after your ride. Working hard in cold dry weather can be dehydrating. Pack along a bottle of water or sport drink too.

Stay Safe During  Hunting Season


No Heimlich for Horses


Wrapping your arms around a 2,000-pound Percheron, or even a 900-pound Arabian, might not be possible unless you are Hulk Hogan. Even at that, you might have a hard time locating your mare's belly button so you can place your hands slightly above it for compressions.

Unfortunately, even if you could do the Heimlich maneuver on your equine friend, it probably would not help. That's because choke in horses is completely different than when a human chokes, at least from an anatomical perspective.

Eric Carlson, DVM, an equine intern at the University of Illinois Veterinary Teaching Hospital in Urbana explains that, "choke is an obstruction of the esophagus," not an obstruction of the windpipe as when a human chokes. He goes on to note that it can be caused by several factors. "Feed impaction due to poor dentition or ravenous eating habits are the most common reasons horses get choke," says Carlson. Foreign material such as apples and wood chips can also cause the problem.

While a child choking on a piece of hot dog may grasp their neck before turning blue, a horse presents differently. "Horse owners should look out for signs of excessive salivation, coughing, and food dripping from their nostrils," says Carlson.

If you suspect that your horse has choke, do not hesitate to call your veterinarian. In the meantime, Carlson recommends that you remove hay and water immediately to prevent worsening the problem. Although the animal can continue to breathe, "if left untreated, horses can get aspiration pneumonia, and the material lodged in the esophagus can cause mucosal damage and necrosis," notes Carlson.

As far as what your veterinarian can do out in the field to help your horse, "the initial aim of treatment is to reduce the patient's anxiety level and allow esophageal relaxation," explains Carlson. This noninvasive method of trying to treat choke can be done with drugs that your veterinarian would commonly have in the truck.

In an ideal world, an endoscope, a flexible wire with a camera on the end, would be used to make sure that the animal is indeed choking. However, not all veterinarians will have access to a scope, and may choose to use a nasogastric tube, a flexible plastic tube that travels from the horse's nostrils to their stomach, to try and dislodge the obstructed material.

Carlson notes that, "if, after passing the nasogastric tube, the situation does not resolve, I lavage the esophagus with water." Hopefully with a combination of these treatments the obstruction will dissolve. However, if the obstruction is too great, an esophagotomy can be performed. Such a procedure entails cutting into the horse's esophagus to remove the ingested material causing the problem.

To prevent choke, Carlson recommends making sure your horse has proper dental care. Also, if your horse tends to eat its food as fast as a lineman after a big game, go ahead and place a large rock in the feed pan to slow him down.

Fall hunting season opens this month in many parts of the country. Here are five ways to protect yourself and your horse from being mistaken for quarry whether you're on the trail or outdoors at home.
 
        1. Ride in a group. The more horses and riders, the more conspicuous you'll be in the woods.
            Talk, laugh or sing as you go to make your presence known.
        2. Be visible. At minimum, wear a blaze orange hunting vest. Consider outfitting your horse in
            Day-Glo leg wraps and weaving bright orange surveyors flagging tape into his mane and tail.
        3. Check in with local landowners. If you routinely ride across their property, verify that you're
            still welcome during hunting season. Many people lease lands to hunters in the fall.
        4. Patrol your own property. If you notice signs of unauthorized hunting, including salt blocks
            or deer stands, check with local game officials about your recourse. Post "no hunting" signs
            that meet local requirements.
        5. Turn out horses in nearby paddocks cleared of trees. If necessary, temporarily relocate them
            from remote, wooded areas until hunting season is over.

 


Contracted Foal Syndrome
Equine Disease Quarterly

The skeletal anatomy of a horse’s front and hind limbs is comparable to the anatomy of the human hands and feet. The horse’s cannon bone, or metacarpal, is the same as a bone in the palm of a hand. The human phalanges, or finger bones, are comparable to the bones making up a horse’s hoof and pastern. Fortunately, most humans and horses are born with normal limbs. However, both children and foals can be afflicted with contracted limb abnormalities.   

When a child is born with tightly clenched fists and club feet, it may have one of several muscle contracture syndromes collectively known as Distal Arthrogryposis (DA). The child may or may not have other congenital abnormalities, such as spinal curvature (scoliosis), facial muscle contractures, or a small mouth.  

DA is caused by mutations in one or more genes that control skeletal muscle contraction. These gene mutations cause abnormal muscle protein production that disrupts normal muscle function. The skeletal muscles contract but are unable to relax, causing limb contractures during fetal development. Most of the mutations are inherited, but the mode of inheritance can vary. Symptoms can vary markedly within and between families. Mutations can arise spontaneously as new (de novo) mutations. Some children with DA respond to surgery and physical therapy; others do not.   

When a foal is born with limb contractures preventing it from standing or walking normally, it is said to have contractures, or Contracted Foal Syndrome (CFS). CFS is the most common congenital anomaly in horses diagnosed at the University of Kentucky’s Livestock Disease Diagnostic Center (LDDC). The signs of CFS are similar to those seen in human DA. The severity of CFS varies in horses, just as DA varies in humans.   

Foals may have a mild form of CFS or exhibit only one affected limb. They may recover with surgery, splinting, or other therapy. Alternatively, foals may present with severe CFS involving contractures of all four limbs and may exhibit other anomalies, including neck flexion (torticollis), facial bone deviation (wry nose), and spinal curvature (scoliosis). Muscle, tendon, and ligament tissues appear normal when examined microscopically by pathologists. CFS has been found primarily in Thoroughbreds at the LDDC, which may be a reflection of the Thoroughbred-dominant equine population in Central Kentucky—other breeds may dominate in other parts of the country. The condition appears to be distributed equally between males and females. If severely affected foals survive delivery, they are usually euthanized due to the inability to stand and nurse.   

Mares carrying foals with CFS may experience dystocia at delivery, thus endangering the life of the mare. Although CFS is not widely regarded as an inherited disease, breeding records indicate that a hereditary risk factor may exist. Some mares have produced up to four CFS foals, each one sired by a different stallion. These mares may have been housed on different farms during each pregnancy, therefore ruling out a management component. Findings in individual cases suggest CFS may be inherited in a dominant fashion, with its development depending on other genetic factors. That would explain why some foals have a mild form of CFS and others have a severe form.

The availability of the horse genome sequences is facilitating our study of CFS. The DNA sequence information for any horse gene of interest can be downloaded from Internet databases. The necessary tools can be prepared for sequencing candidate genes from affected and non-affected individuals. Based on the gene mutations causing DA in humans, we have selected and are currently sequencing candidate genes in an effort to identify mutations that cause CFS.

Even though this research has begun, success will depend on continued support from the horse industry, especially through providing research samples from foals and information on sires and dams that have produced one or more foals with CFS. All information is kept confidential, including the identity of horses and farms. We expect one day to develop a diagnostic test that will provide information to allow farm managers to avoid matings that will produce CFS foals and to determine which foals will respond to treatment. The participation of breeding farms, veterinarians, and horse owners is imperative if the cause of CFS is to be identified.

A Handy First-Aid Item For Your Horse In Your Freezer

Cold therapy can help a variety of your horse’s muscle, tendon and joint injuries. So when ice is what the doctor orders, a bag of small frozen vegetables, such as peas or corn, makes a convenient cold pack.

Don’t want to ruin tomorrow night’s dinner?

Make your own ice pack, using a resealable plastic bag to hold slab or crushed ice. Crushed ice releases its cooling properties more quickly, and the pack will conform more readily to the shape of the area being treated.  You can also make your own flexible ice pack by putting equal parts of water and rubbing alcohol in a resealable plastic bag doubled.

Chemical ice packs, such as the “blue ice” used in picnic coolers, also work well. Commercial ice bandages designed for specific parts of a horse’s leg are also available, as are special chemical pouches that produce a rapid freezing reaction when activated.

Remember, always contact your veterinarian to discuss the symptoms and location of the injury.

Other cold therapy guidelines are:

· A rule of thumb is five minutes on, 15 minutes off until heat and swelling are noticeably reduced.

· Use a damp cloth or cotton sheet as a buffer between the ice pack and the horse’s skin to protect the tissue and dissipate the cold.

· Chemically activated cold packs may require more layers of fabric to buffer the skin and prevent frostbite.

· Do not place ice directly against the skin if there is an open wound. Use several layers of cotton gauze to protect tissue and absorb fluids.

How Cold or Ice Can Help

Applying ice or cold therapy can improve a variety of tendon, joint, muscle and other soft tissue injuries by decreasing blood flow to the damaged area and slowing the metabolism of the surrounding tissue so it is less likely to suffer damage from swelling and constriction.

Cold therapy helps to:

· Reduce Inflammation

· Reduce Swelling

· Dissipate Heat

· Alleviate Pain

· Slow Bleeding

 

When a horse injures a leg, many times the first - and best – course of action is to cool the area as quickly as possible using ice packs or very cold water. Your immediate goal is to try to reduce inflammation and swelling in order to minimize tissue damage and speed healing. Ice slows the inflammatory process while other treatments such as medications can begin to take effect.
Care must be taken, however, whenever cold therapy is applied to a limb. Ice wraps used incorrectly or applied for too long can potentially damage the skin and underlying tissue.
To maximize the therapeutic benefits of ice or cold therapy, follow your veterinarian’s instructions exactly and keep in mind the recommendations contained in this brochure.

Applying Cold or Ice

The best method for applying ice or cold therapy will depend on the type and location of the injury, as well as the materials you have at your disposal.
Ice packs may be either rigid or flexible depending on their contents. You will need to determine what works best for the area you are treating.
You can make an ice pack using a reseal able plastic bag to hold slab or crushed ice. Crushed ice releases its cooling properties more quickly and the pack will conform more readily to the shape of the limb. A bag of frozen vegetables (such as peas & corn) is also a convenient and ready-made ice pack. Chemical ice packs such as the "blue ice" commonly used in picnic coolers also work well. Commercial ice bandages designed for specific parts of the horse’s leg are also available.
There are also special chemical pouches that produce a rapid freezing reaction when activated. Chemical ice packs are especially useful additions to first aid kits.
Another option for lower limbs is to use a bucket or ice boot filled with ice water. Running cold water over the injury site with a hose is also a convenient way to reduce heat and swelling at the injury site.
General Recommendations
1. Contact your veterinarian and explain the symptoms and location of the injury.
2. Request immediate veterinary help if lameness is severe or the horse resists moving.
3. If cold therapy is recommended, begin the initial application as soon as possible. The first 24-48 hours are key.
4. Use proper leg bandage techniques so you can position the ice pack without constricting the blood supply to the leg or damaging tendons.
5. Apply ice for approximately 5 minutes at a time, but no more than 10-15 minutes. A rule of thumb is 5 minutes on, 15 minutes off until heat and swelling are perceptibly reduced.
6. Repeat cold therapy every 4-6 hours within the first day of treatment or as otherwise recommended by your veterinarian.
7. Use a damp cloth or sheet cotton as a buffer between the ice pack and the horse’s skin to protect the tissue and dissipate the cold.
8. Chemically activated cold packs may require more layers of fabric to buffer the skin and prevent frostbite.
9. Do not place ice directly against the skin if there is an open wound. Utilize several layers of cotton gauze to protect tissue and absorb fluids.
10. If possible, place a bandage on the area between treatments to prolong the benefits and help reduce swelling. Again, make sure to use proper leg bandaging techniques.
11.Get veterinary help if the lameness lasts longer than 1 day without significant improvement.

Bandaging Guidelines

When applying an ice bandage, although the bandage will be in place for only short period of time, it is still important to follow these safety guidelines.
- Place a cloth between the ice pack and the skin.
- Use gauze or a bandaging material such as 3M Vetrap Bandaging Tape that has enough strength, stretch and cohesion to conform to the leg and hold the ice pack in place.
- Wrap in a spiral pattern, overlapping layers with smooth, uniform pressure.
- Be careful not to bandage the leg too tightly or create any pressure points. Some veterinarians recommend wrapping from front to back, outside to inside-counterclockwise for left legs, clockwise for right legs-to prevent tendons from being pulled outward from the cannon bone and vessels, and to reduce the likelihood of constriction. While your horse is recovering, pay close attention to its progress. Contact your veterinarian immediately if you observe any of the following:

1. Increased pain or lameness.
2. Discharge from a wound that has a foul odor, unusual color or seems to be excessive.
3. Excessive swelling.
4. Increased warmth at the injury site.
5. Elevated body temperature (100F+ or –1 is considered normal.
6. Decumbency - horse spends an abnormal amount of time lying down.
7. Lack of appetite or depression.

Talk with Your Veterinarian
If you have questions or concerns, your equine veterinarian will be your greatest asset. Do not hesitate to call. He or she can address problems that need to be handled or alleviate any unnecessary worry. It is a health care partnership, with your horse’s well being at the heart of it.

How a Horse's Hoof Grows

Hoof growth is one of the most important considerations in hoof physiology. Hoof growth occurs from the coronary band down toward the toe. The average hoof grows 1/4 to 3/8 inch per month. Since the average hoof is 3 to 4 inches in length, the horse grows a new hoof every year.

Rapidly growing hooves are considered to be higher quality and easier to keep properly trimmed and shod. Factors that effect hoof growth are age, season, irritation or injury of sensitive structures, and nutrition.

Age

Hoof growth rate seems to be highly correlated to heart rate. Young horses have a higher heart rate than that of older horses. Similarly, young horses have a faster hoof growth rate than older horses. Hoof growth rate decreases as the horse ages. The hooves of horses under 1 year of age grow about twice as fast as those of horses more than 12 years of age. Highly conditioned horses have a lower heart rate than idle horses, but their hoof growth is faster. It appears that the exercise they receive offsets the effect of the slower heart rate.

Summary of the effect of age on horse hoof growth rate.

Class of Horse(mm per day)(mm per mo.)(in. per mo.)
Foals0.5015.00.60
Yearlings0.4012.00.50
Mature0.309.00.33
Aged0.206.00.25

Taken from Principles of Horseshoeing II. Bulter, D. K. 1985. Butler Publishing


Hind hooves grow 12 percent faster than front hooves in foals and approximately 7 percent faster in weanlings. Differences between hind and front hoof growth diminish as horses age, with no difference apparent by the time they are yearlings. Hoof size has no effect on hoof growth rate. Hoof size except is a function of age.

Season

A horse’s hoof grows faster in the spring of the year than other seasons. This growth rate may be influenced by climate. Hoof growth slows during the winter months.

Sensitive

Structures Stimulation of the sensitive structures by strong counter-irritant products or massage is thought to increase hoof growth. However, research indicates that these products do not significantly affect hoof growth. Systemic fever or injury of the sensitive structures results in rapid hoof growth.

Nutrition

Level of nutrient intake has been shown to affect hoof growth. Proper nutrient intake stimulates maximum hoof growth. Biotin supplementation is suggested to improve hoof growth and integrity over time. After several months of feeding biotin, some horses show increased hoof integrity and quality. However, not all horses respond to biotin supplementation. Hoof quality and growth is most affected by proper nutrition, which involves feeding a properly balanced ration.

 

 

No Hoof, No Horse - How Nutrition Affects Hoof Growth

Karen E. Davison, Ph.D.
Equine Nutrition Purina

 

Everyone is familiar with the famous Benjamin Franklin quote, “For want of a nail the shoe was lost, for want of a shoe the horse was lost, and for want of a horse, the rider was lost, being overtaken and slain by the enemy – all for want of care about a horse-shoe nail.” While Benjamin Franklin meant this quote as an example of how ignoring the little things can lead to failure in the bigger picture, most of us have taken this to illustrate the vital importance of healthy hooves to the soundness and performance of the horse. Hoof quality is affected by several factors including genetics, environment and nutrition. Some horses inherit weak hooves and that can’t be changed, but proper care and nutrition can help develop and maintain the best hooves genetically possible. On the other hand, a horse may have the genes for great hooves, but improper care and inadequate nutrition can lead to hoof problems for that horse.

There are several nutrients that can influence hoof growth and quality, but there is very little evidence to suggest that the addition of extra nutrients to an already balanced diet will promote hoof growth in the normal horse. Energy or calorie content of the diet can have an impact on hoof growth. Research has shown that feeding young growing horses a lower calorie diet that led to reduced weight gain also resulted in slower hoof growth. Protein deficiency can have the same effect as energy deficiency since hoof structure is primarily keratin, a protein. The hoof growth of weanlings fed 9% protein was only two thirds that of weanlings fed 14% protein. Growth and calcium metabolism in horses fed varying levels of protein. (Schryver, HF, Meakim, DW, Low JE, Williams, J, Soderholm, LV, Hintz, HF. Equine Vet J. 1987. July 19(4). 280 -7. Nutrition. Section 2. Hintz, HF. In:robinson, NE (ed). Current therapy in equine medicine 1st edition. W. B. Saunders Company. Philadelphia, 1983. 65-118.) Proteins are made up of different amino acids and the amino acid concentration within the horn of good quality hooves has been shown to be different from that of poor quality hooves. However, studies have failed to show an effect of specific amino acid supplementation on the growth of hooves. While the essential amino acid methionine is thought to be important for hoof quality, if fed in excess it is thought to cause a depletion of iron, copper and zinc which may be associated with crumbling horn and white line disease. Fats are needed by the hoof to create a permeability barrier which assists in cell to cell adhesion, helping prevent bacteria and fungi from penetrating the horn. Diets containing adequate levels of fat can therefore be beneficial to the hoof.

A proper balance of minerals is also important to hoof growth and quality. For example,
zinc has been shown to be important in the normal keratinization of the hoof. Horses with insufficient hoof horn strength had less zinc in the hoof horn and plasma than did horses with no hoof horn damage. Calcium and phosphorus, and the ratio of one to the other, also has an impact on hoof development. Calcium is needed for cell to cell attachment in the hoof horn. Calcium is also important in the metabolism of the intercellular lipids. Excess phosphorus can block the absorption of calcium from the small intestine which ultimately can cause weak and abnormal bones and affect cell to cell attachment. Selenium is important as an anti-oxidant for the protection of cellular membranes. However, excess selenium in the diet can lead to substitution of sulfur in the keratin fibers with selenium, resulting in poor structural integrity. Chronic selenium toxicity can result in hair loss, coronitis and bleeding of the coronary band as well as sloughing of the hoof and even laminitis.

The most investigated vitamin related to hoof growth is biotin, a water soluble vitamin that is manufactured by microbes in the digestive system. Controlled studies have reported varying results on the effect of biotin supplementation on hoof growth and quality. Some studies found biotin supplementation to help some horses grow better hooves, other studies found no advantage and one study reported a reduced growth rate with biotin supplementation. In the studies that found improvement, the level of supplementation was 10 – 30 mg of biotin per day over a 9 – 38 month period, and improvement was observed in some but not all of the horses. Josseck, H., Zenker, W, Geyer, H. Hoof horn abnormalities in Lipizzaner horses and the effect of dietary biotin on macroscopic aspects of hoof horn quality. Equine Veterinary Journal. 1995. May. 27(3): 175-182; Comben, N. Clark, RJ, Southerland, DJ. Clinical observations on the response of equine hoof defects to dietary supplementation with biotin. Veterinary Record. 1984. 115:642-645 With horses that have poor hoof quality despite good environment and balanced nutrition, there may be some benefit from a therapeutic dose of biotin supplementation. But for the majority of horses, a diet with naturally occurring biotin, a good amino acid and fatty acid balance, and proper vitamin and mineral fortification will support excellent hoof growth rates and quality of growth.

There are several nutrients that can exert a direct influence on the growth rate and integrity of the hoof. It is the balance of these nutrients with each other that is most important in the growth of a normal hoof.

Internal parasites are silent killers.  They can cause extensive internal damage, and you may not even realize your horses are heavily infected.  At the very least, parasites can lower resistance, rob the horse of valuable nutrients, and cause gastrointestinal irritation and unthriftiness.  At their worst, they can lead to colic, intestinal ruptures, and death.

            Using deworming agents on a regular schedule in combination with good management procedures is critical to relieving your horse of most parasites. Since parasites are primarily transferred through manure, good management is key.  In terms of management priorities, establishing a parasite control program is probably second only to supplying the horse with clean, plentiful water and high quality feed.

            To get rid of parasites before they attack your horse, follow these suggestions from the American Association of Equine Practitioners (AAEP):

1.     Pick up and dispose of manure droppings in the pasture at least twice weekly.

2.     Mow and harrow pastures regularly to break up manure piles and expose parasite eggs and larvae to the elements.

3.     Rotate pastures by allowing other livestock, such as sheep or cattle, to graze them, thereby interrupting the life cycles of parasites.

4.     Group horses by age to reduce exposure to certain parasites and maximize the deworming program geared to that group.

5.     Keep the number of horses per acre to a minimum to prevent overgrazing and reduce the fecal contamination per acre.

6.     Use a feeder for hay and grain rather than feeding on the ground.

7.     Remove bot eggs quickly and regularly from the horse’s haircoat to prevent ingestion.

8.     Rotate deworming agents, not just brand names, to prevent chemical resistance.

9.     Consult your veterinarian to set up an effective and regular deworming schedule.

With the many safe, convenient products available today, establishing an effective deworming program is easy.  Discuss a plan with your veterinarian and implement it without delay.  A good parasite control program will go a long way toward maximizing your horse’s appearance, performance and comfort.  The net result will be an animal that is as healthy on the inside as it appears on the outside.

For more information about waging war on equine parasites, ask your veterinarian for a copy of the “Parasite Control” client education brochure, provided by the AAEP in partnership with Educational Partner Bayer Animal Health.  Information about equine parasites also can be found in the horse owner section on www.aaep.org.

Equine Rabies
By D. Craig Barnett. DVM

 

Although the incidence of rabies in horses is rather low, the disease is still of a serious nature as it is invariably fatal and there is often significant potential for human exposure. While reported cases maybe low as not all horses that die or are euthanized due to neurological signs are tested for rabies. The number of rabies cases in both wildlife and domestic animals has increased over the last 20 years with reported cases in wild and domestic animals generally exceeding 9,000 annually. With the continued increase in the number of rabies cases, the threat and potential exposure to the horse is also likely to increase. The disease as it relates to horses is of significant concern due to the infectiousnature and severity of the disease, the potential for human exposure, and because the presenting clinical signs can be extremely variable and nonspecific.


With the increased urbanization of areas in which the disease is endemic in wildlife populations, the risk of exposure continues to be a concern for horse owners and veterinarians.

Rabies is an acute viral disease that attacks the central nervous system of its victim. Theetiologic agent is a virus which can cause disease in any warm blooded animal. The rabies virus pool is largely maintained by certain wildlife species. In North America, the predominant natural reservoirs for infection are skunks, foxes, raccoons and bats. Herein the Midwest, the skunk is the most common reservoir for rabies infection in wildlife. Horses frequently come in contact with these wild animals in barns and pastures. The horse is one of the most susceptible domestic animals and is usually infected via a bite wound from a rabid wild animal. Bites from wild animals are often on the muzzle or lower legs of the horse and generally go unnoticed. Rarely is the exposure to the wild animal observed, and bite wounds on the horse are rarely found. In one retrospective study of 21 horses with rabies, bite wounds were not found on any of the horses. Because the rabid animal has a high concentration of rabies virus in its saliva, its’ bite inoculates the bite victim. The virus then replicates and travels up the peripheral nerves to the central nervous system. The incubation period, which is the time between the viruses entry into the body and the onset of clinical signs, averages tow to nine weeks but may be as long as fifteen months.

CLINICAL SIGNS
Equine rabies can have many different clinical manifestations and a wide variety of nonspecific and confusing clinical signs have been reported. For this reason, the disease is frequently initially misdiagnosed. It is often stated that rabies can “look like anything”. Colic, lameness, ataxia (incoordination), paralysis, urinary incontinence, muscle tremors, fever, depression, aggressiveness, hyperesthesia  (increased sensitivity to touch or other stimulation), and convulsions are some of the most commonly reported clinical signs. Because of the extreme variability in clinical signs, it is difficult to make generalizations. However, most horses exhibit some degree of hyperesthesia, fever, and neurological signs (atazia and/or paralysis) at some point during the course of the disease. While some horses exhibit intermittent or continuous signs of aggression, affected horses are more typically depressed or stuporous. Some horses may become anorectic and refuse to drink while others will continue to eat and drink until shortly before death. Hydrophobia (fear of water) is not a frequent sign in the horse. Occasionally, horses exhibit signs of ptyalism (grinding of the teeth). Obscure lameness and posterior ataxia (incoordination) are relatively common early signs. I observed a horse at a veterinarian clinic that presented with a rear limb lameness and ended up progressing to show neurological signs and being diagnosed as a case pf raboes.

In most horses, the progression of the disease is rapid with death in three to five days follosing the onset of clinical signs. Prior to death, most horses will become recumbent with conbulsions and/or a comatose state and violent thrashing. Rabies infection in the unvaccinated horse is invariably fatal.

DIAGNOSIS
Rabies should be high on the list of differential diagnosis for any horse exhibiting obscure neurological signs, especially if the horse is in an endemic area. Currently, there are no diagnostic tests, which can be performed on a live animal which are accurate enough to be of practical use. The highly variable, nonspecific clinical signs of equine rabies along with the lack of accurate diagnostic tests, makes the diagnosis of rabies in the live horse very difficult. Rabies therefore, remains a disease in which the diagnosis is most often made only after death during postmortem examination of the brain and spinal cord. Because of the rapid progression of the disease, if undiagnosed neurologic disease in the horse has not rapidly progressed by day 5 after the onset of clinical signs, rabies can probably be considered less likely to be the infective agent. However, because of the
Serious threat to human life, any suspected case of equine rabies should be handled as if it were a positive until proven otherwise.

TREATMENT
Currently, there is no treatment for rabies and infected horses invariably die. Since many rabies cases present as undiagnosed neurologic disease, supportive care and sysptomatic treatment is often initiated. Horses that are known to have been exposed to rabies should have all wounds cleaned and lavaged with iodine or quaternary ammonium disinfectant. The virus is relatively fragile and is killed by most disinfectants (including 70 oercent isopropyl alcohol, providone iodine, quaternary ammonium compounds, etc.), ultraviolet light, and heat. The birus dies in dried saliva within hours and will die in a carcass within 24 hours at 20-C (68 F). However, the virus survives longer at colder temperatures, living for days in carcasses under cold conditions. In a known exposed horse, rabies antiserum, if available, should be infiltrated around the area of the bite would. Unfortunately, as mentioned previously, most exposures are not observed and most bite wounds are not found. Because of the serious public health risk and the invariably fatal nature of the disease, if a horse is showing clinical signs and a diagnosis of rabies is made, treatment is not advocated and euthanasia should be performed immediately.


PREVENTION
Although there may be some differences of opinion with regards to vaccination of horses against rabies, it is my opinion, and the opinion of many others, that vaccination of companion animals, including the horse, cannot be overemphasized. All horses kept in areas where rabies is endemic in the wildlife population (such as the Midwest) are at risk and should be vaccinated. There are several key points to consider regarding vaccination: 1) the incidence of rabies in both wild and domestic animals is on the increase 2) it is not uncommon for pastured or stalled horses to be unknowingly exposed to wildlife 3) most exposures are not noticed and most bite wounds are no found 4) there is a significant and serious potential for human exposure from an infected animal 50 because horses are often kept in close contact with people, vaccination of the horse may serve to establish an immune barrier between humans and wildlife 6) equine rabies cases are invariably fatal 7) vaccination of horses against rabies is safe and although not 100% effective, is generally highly protective and 8) when dealing with a horse showing neurological signs, the concern for rabies can be somewhat minimized in a horse known to have been properly immunized.

POSREXPOSURE MANAGEMENT
Rabies is considered a “reportable disease”. The National Association of State Public Health Veterinarians currently recommends that a vaccinated horse which has been bitten by a wild animal should be considered exposed to rabies and should be revaccinated immediately and observed for 90 days. An unvaccinated horse known to have been exposed should be euthanized immediately. If the owner is unwilling to euthanize an exposed, unvaccinated horse, the horse should be kept quarantined under observation for six months.

Although the transmission of rabies from horses to humans appears to be rare, and the incidence of equine rabies low, the human risk associated with exposure to a rabid animal remains a serious concern and the disease is invariably fatal to the horse. Consult with your veterinarian regarding any questions you may have with regards to rabies and vaccination for your horse.

 

Breeding Your Mare


It's not to early to start looking for the perfect match for your mare.  You may not have a gelding or a teasing stallion, to tell you when she is ready,so understanding a little about how your mares reproductive system works cna be helpful. 

 

The mare's breeding year is divided into two parts: Anoestrus and Oestrus.

Anoestrus

This is the period where the mare is not receptive to the stallion, does not show regular signs of being 'in season' and can be more stable in her moods.

Oestrus

Oestrus is the period where the mare exhibits good regular 'seasons' and she will 'show' and be generally receptive to the stallion during teasing. When in the prime of her cycle she will stand willingly for the stallion in order to be mated. Oestrus is the beginning of the ovulatory season.

Hormonal reasons for the states of breeding in the mare

Daylight periods are perceived by light receptors in the eye which results in an effect on the pineal gland that releases a hormone known as Melatonin. When Melatonin levels increase, as the result of increased daylight hours, this results in the onset of oestrus, ie the breeding season. There are several hormones that become active to result in the oestrus period:

  • Increased Melatonin levels effect the hypothalamus part of the brain which in turn results in the increased release (from the hypothalamus) of Gonadotrophin Releasing Hormone(GnRH).
  • GnRH affects the anterior pituitary gland to induce the release of Follicle Stimulating Hormone(FSH) and Luteinizing Hormone(LH).
  • FSH & LH have an effect on GnRH and gonadotrophins and vicer versa during the oestrus cycle in a rhythmic fashion that repeats approximately every 22 days until the sequence is either interrupted by pregnancy, change in season or pathological reasons.

At the same time as the hormones released from the brain are being produced the ovary is also producing hormones in a similar pattern.

The ovary goes through several stages in the 22 day cycle:

  1. Growth of follicles in the ovary results in the release of follicular oestrogen
  2. Release of ovum on stimulation by LH which results in the development of the Corpus Luteum (Ovary post ovulation) and a reduction in follicular oestrogen.
  3. Growth of Corpus Luteum resulting in increased progesterone production.
  4. In the event of no pregnancy the Corpus Luteum begins to decline resulting in the reduction of progesterone.
  5. The cycle begins again with the growth of follicles and the release of oestrogen.

The Oestrus cycle is divided up into two distinct phases; oestrus and dioestrus:

  • Oestrus - this is the period (5-7 days) where the mare exhibits signs of receptivity to the stallion. Usually this behaviour begins to wane about the time of ovulation although some mares may carry on for a further 1-2 days post ovulation. Ovulation coincides with the LH peak rise resulting in increased follicular oestrogen and ovulation of one ovum from the ovary.
  • Dioestrus - this is the period where the mare is not receptive to the stallion. Her progesterone levels are high and the corpus luteum is in evidence. This period usually last 14-16days.

The end of one oestrus phase and the beginning of another is marked by ovulation and is often used as a reference point for relating various events during the cycle.

Ovulation is taken as day 0.

10 Tips for Preventing Colic


 

The number one killer of horses is colic.  Colic is not a disease, but rather a combination of signs that alert us to abdominal pain in the horse.  Colic can range from mild to severe, but it should never be ignored.  Many of the conditions that cause colic can become life threatening in a relatively short period of time.  Only by quickly and accurately recognizing colic – and seeking qualified veterinary help – can the chance for recovery be maximized.

 

While horses seem predisposed to colic due to the anatomy and function of their digestive tracts, management can play a key role in prevention.  Although not every case is avoidable, the following guidelines from the American Association of Equine Practitioners (AAEP) can maximize the horse’s health and reduce the risk of colic:

 

  1. Establish a daily routine – include feeding and exercise schedules – and stick to it.

  2. Feed a high quality diet comprised primarily of roughage.

  3. Avoid feeding excessive grain and energy-dense supplements. (At least half the horse’s energy should be supplied through hay or forage.  A better guide is that twice as much energy should be supplied from a roughage source than from concentrates.)

  4. Divide daily concentrate rations into two or more smaller feedings rather than one large one to avoid overloading the horse’s digestive tract.  Hay is best fed free-choice.

  5. Set up a regular parasite control program with the help of your equine practitioner.

  6. Provide exercise and/or turnout on a daily basis.  Change the intensity and duration of an exercise regimen gradually.

  7. Provide fresh, clean water at all times.  (The only exception is when the horse is excessively hot, and then it should be given small sips of luke-warm water until it has recovered.)

  8. Avoid putting feed on the ground, especially in sandy soils.

  9. Check hay, bedding, pasture, and environment for potentially toxic substances, such as blister beetles, noxious weeds, and other ingestible foreign matter.

  10.  .Reduce stress.  Horses experiencing changes in environment or workloads are at high risk of intestinal dysfunction.  Pay special attention to horses when transporting them or changing their surroundings, such as at shows.

 

Virtually any horse is susceptible to colic.  Age, sex, and breed differences in susceptibility seem to be relatively minor.  The type of colic seen appears to relate to geographic or regional differences, probably due to environmental factors such as sandy soil or climatic stress.  Importantly, what this tells us is that, with conscientious care and management, we have the potential to reduce and control colic, the number one killer of horses.

 

 

For more information about colic prevention and treatment, ask your equine veterinarian for the “Colic” brochure, provided by the AAEP in partnership with Educational Partner Bayer Animal Health.  Additional colic information is available by visiting the AAEP’s horse health web site, www.myHorseMatters.com.

 

The American Association of Equine Practitioners, headquartered in Lexington, Ky., was founded in 1954 as a non-profit organization dedicated to the health and welfare of the horse.  Currently, the AAEP reaches more than 5 million horse owners through its over 9,000 members worldwide and is actively involved in ethics issues, practice management, research and continuing education in the equine veterinary profession and horse industry.

Foot Abscesses


by Frosty Franklin, DVM
Edgecliff Equine Hospital
S. 1322 Park Road, Spokane, WA 99212 * 509/924-6069


The horse's hoof is a very durable, tough structure that is constantly renewing. The hoof is always in contact with the environment and, as such, experiences a wide variety of traumatic insults that occasionally damages the hoof and enclosed structures. One of the most common problems occurring to the hoof is the introduction of bacteria and other microorganisms to the sensitive structures within the hoof. A hoof abscess is the result.

 

A hoof abscess, in my mind, is either a direct hoof abscess caused by penetrating wounds or an indirect hoof abscess caused by the migration of moisture and bacteria into fissures and cracks along the white line.

Almost always when the horse is acutely lame to the point where weight bearing on the affected limb is difficult, the diagnosis is a hoof abscess. Rarely, that non weight-bearing stance is caused by a fractured bone somewhere within that affected limb. By examining the foot for heat and swelling just above the foot in the pastern and fetlock and by evaluating the digital arterial pulses the owner can quickly rule in or rule out a hoof abscess.

In talking with my clients I was amazed to find a large percentage of horse owners that are not aware of the importance of being able to check for the presence of pulses within the digital arteries. In the normal resting horse the digital arterial pulses are not palpable. The digital arteries are present on each side of the pastern. The digital vein is visible on each side of the pastern in most horses, especially if the hair on the pastern is clipped. The digital artery is just slightly posterior to the vein, the vein being a good visual landmark. Whenever inflammation or infection occurs in the foot, the pulses in the digital arteries are obvious to anyone that feels for them. It would be a good idea for horse owners to become familiar with the digital arterial pulses and how to palpate for them. Ask your veterinarian for help if you are confused about the anatomy. Check your horse right after exercise, because then the pulses are palpable.

 

Penetrating wounds of the hoof can be very serious and should be treated as a potential career ending or life-threatening wound. It is difficult to tell which of the vital structures of the foot have been injured and contaminated with microorganisms. Penetrating wounds of the middle third of the frog are particularly scary because in this region the navicular bone and bursa are present, as well as the deep flexor tendon and the coffin joint. Some of the puncture wounds to the hoof are well hidden by the spongy, elastic frog or the dark dirt-filled sulci and go undetected. In other cases, the nail is simply removed, some iodine squirted in the wound and the incident is not taken seriously and several days may have lapsed before treatment is sought. By then a very serious situation has precipitated requiring surgery, long-term antibiotic therapy, and special hoof care with only a fair chance of returning to full use. In one study, 12 of 38 horses with puncture wound to the navicular bursa or navicular bone returned to satisfactory function.

 

Fortunately, indirect hoof abscess are much more common. In our practice, they occur when the footing is wet. Defects and fissures in the white line allow the moisture, manure and bacteria access to the sensitive structures to form this type of abscess. These abscesses are relatively easy to treat if the fissure is readily located. These fissures and the structurally comprised white line are common in chronic laminitic (foundered) horses. The "stretched" or widened, pithy white line does not have the integrity of a normal white and allows filth access to the sensitive tissues of the foot. Horses that are recently trimmed and then exposed to muddy/mucky corrals also seemed to be predisposed to a indirect hoof abscess. The infection that gains access to the foot through the white line may travel up the sensitive lamina underneath the hoof wall forming a "gravel" that drains at the coronet. Or much more likely, the infection involves the sole and becomes a sole abscess. This type of hoof abscess is very painful but usually resolves within a few days with proper treatment.

 

Diagnosing indirect hoof abscess is usually straightforward. Examining the foot for heat, pain, and swelling. Removing the shoe, and proper cleaning of the hoof with a hoof pick and hoof knife is essential. Paying particular attention to the coronet, frog, sulci, and the white line. The hoof testers can be very useful or they can make the horse very defensive because you apply them too forcefully at the beginning. Once the black line or fissure is identified the line is followed with the hoof knife and most of the time grayish exudate will drain the abscess.

Establishing surgical drainage is the most important aspect of therapy. A small loop knife works well. Once a small drainage hole is created the foot may be soaked in hot Epsom salt solution (2 cups per gallon of very warm water). Instead of soaking, I usually apply Magnapaste ointment and bandage the hoof. Magnapaste is an osmotic and "draws" the abscess. Recently, over the bandage I have been applying a new product called the "Equine Slipper." The Equine Slipper has a thick leather bottom and the upper part is breathable cordura nylon with handy Velcro fasteners. It seems to protect the bandage and keeps the hoof clean. Tetanus toxoid should be administered if the horse has not been vaccinated within the last 6 months. I usually prescribe phenylbutazone: 2 grams daily for 6 days.

 

Penetrating wounds or direct hoof abscess are managed more intensely. The penetrating object is best left in place. The veterinarian is summoned and the hoof radiographed. Even then, evaluating all the structures involved is difficult. Dr. Schneider at Washington State University College of Veterinary Medicine is using MRI to evaluate the structures of the foot damaged by puncture wounds. The more information one can delineate the more accurate the diagnosis and prognosis. Treatment of these direct abscesses many times is difficult. Surgical curettage of bone infections to the third phalanx or navicular bone caused by nails puncturing the bone, debriding the deep flexor tendon and drainage of the navicular bursa or joint lavage of the coffin joint are procedures requiring expertise and considerable expense. The prognosis is guarded to unfavorable in many cases. If the penetrating object does not encounter a vital structure as around the periphery of the hoof, most of the time the prognosis for complete recovery is good.

 

Some hoof abscess can be prevented. Start by keeping the barnyard and stable free of nails and other sharp objects that can penetrate the hoof. They are the number one cause of penetrating injuries to the foot.

Should an acute lameness occur, seek veterinary attention early. Early treatment usually has a higher success rate. Anatomy of equine foot

 

Advise from a holistic vet  www.harmanyequine.com

 To help prevent a regular abscess from becoming more severe. One is a product called Draw, which is a liquid poultice made from concentrated mineral springs. Mixed in the dilutions on the bottle, it is safe to use in open wounds. I will pack a hole in the foot with a bit of roll cotton soaked in Draw to help clean and soak up any drainage. It can be used as a foot soak, in place of Epsom salts, or the coronet band can be wrapped in a piece of cotton soaked in Draw. Sometimes the veterinarian may not want the whole foot soaked, which, if done too much, can soften the hoof wall and structures--much like your fingernails get too soft in the bathtub.

The other treatment that can be done is to put a bit of cotton into the hole with some Tea Tree oil or Oregano Oil (or a 50:50 mix of both). The cotton does not need to be soaked, just good and damp with the oil. If the hole is too small for a piece of cotton to stay in, just drip a few drops of the oils into the hole. For many smaller abscesses, I just place the cotton in the hole with the oil(s), and pack it in well. The horse can be turned out with this cotton protecting the hole from dirt, and in most cases the cotton will still be there and the inside will be clean when you change it the next day. This is a much simpler method of protecting the hole than trying to keep bandages on during turnout. Obviously if he is very lame, your horse may need to stay inside and may need a bandage.

 

Abscesses can be difficult to see with your eye alone. 

The abscess is at the end of the nail. 

Putting pressure on the sole of the foot can help in locating them using hoof testers.

Whenever inflammation or infection occurs in the foot, the pulses in the pasturn area arteries are obvious to anyone that feels for them.

Many times there will also be a foul odor present as you clean out the foot.

Usually there is a grayish to black color at the abscess that is a different texture than the healthy tissue.

You can sometimes feel heat and obvious lameness.

 

Skunk Shampoo


Hopefully you won't need this to often, but one thing is for sure when you need it YOU NEED IT!!


this is a fabulously simple and effective remedy for those times your dog/horse meets up with a black and white pussy cat of the smellier persuasion. And since most of us own dogs, it will come in handy at some point in our life.


1 quart hydrogen peroxide
(3%, from the store)
1/4 cup baking soda
(any brand)
1 tsp. liquid detergent (The soap is needed to cut the natural oils in the dogs coat. (shampoo, dish soap, etc)

Mix and apply. Often, you only need to wipe it on the surface of the coat, if you catch it before your friendly canine has rubbed it deep into his coat. You can make up a 1/2 batch if this is the case.

 

Ten Tips For Caring For Older Horses


Because of advances in nutrition, management and health care, horses are living longer, more useful lives. It’s not uncommon to find horses and ponies living well into their 20s and 30s.  While genetics play a role in determining life span, you too, can have an impact.

 

You may think that turning your old-timer out to pasture is the kindest form of retirement. But horses are individuals.  Some enjoy being idle; others prefer to be a part of the action.  Whatever you do, don’t ignore the horse.  Proper nutrition, care and exercise will help the animal thrive. Follow these guidelines from the American Association of Equine Practitioners (AAEP) to develop a total management plan for your older horse:

 

1.     Observe your horse on a regular basis.  Watch for changes in body condition, behavior and attitude. Address problems, even seemingly minor ones, right away.

2.     Feed a high quality diet.  Avoid dusty and moldy feeds.

3.     Feed your older horse away from younger, more aggressive ones so it won’t have to compete for feed.

4.     Feed at more frequent intervals so as not to upset the digestive system. Two to three times daily is best.

5.     Provide plenty of fresh, clean, tepid water.  Excessively cold water reduces consumption, which can lead to colic and other problems.

6.     Adjust and balance rations to maintain proper body conditions.  A good rule of thumb is to be able to feel the ribs but not see them.

7.     Provide adequate, appropriate exercise to maintain muscle tone, flexibility and mobility.

8.     Groom your horse frequently to promote circulation and skin health.

9.     Be aware that older horses are prone to tumors.  Look for any unusual lumps or growths from head to tail as well as beneath the tail (especially on gray horses).

10.  Schedule routine checkups with your equine veterinarian.  Call immediately if you suspect a problem.

 

A quick response to ailments, injuries or a decline in fitness can keep your older horse from having a serious or prolonged setback.  That means less worry for you and a better quality of life for your old friend.  For more information about caring for the older horse, ask your equine veterinarian for the “Older Horse” brochure, provided by the AAEP in partnership with Educational Partners Bayer Animal Health and Purina Mills, Inc.  Visit the AAEP’s horse health web site, www.myHorseMatters.com, for additional information about caring for the older horse.

Summer Heat is Here

by Linda Ann Nickerson
All winter, horse lovers dream of balmy summer days, when we can gallop across the countryside on our favorite horses. However, once those lazy and hazy summer days arrive, we must take extra precautions to keep our horses cool!

WATCH FOR HEATSTROKE

A horse's normal body temperature is 100 (F). If it rises much over that, a horse can quickly develop heatstroke. In severe cases, this can cause neurological problems or fatality. Overweight or overexerting horses are particularly prone to this.

Horses suffering from severe heatstroke may need a few weeks of rest from work, as part of the recovery process.

GUARD MARES AND FOALS CAREFULLY

Nursing mothers must be protected from heatstroke and dehydration, as they must continue healthy lactation to feed their foals adequately.

Foals are typically born in the spring and summer. Newborns are particularly at-risk for overheating on hot, humid days. Simply put, their internal thermostats are not ready to deal with drastic temperatures. Foals should not be left out in a hot sunny pasture during the peak hours of the day (10 am to 3 pm).

AVOID ANHYDROSIS

Anhydrosis is the inability to perspire. Arabians, Quarterhorses, Standardbreds, Thoroughbreds, and other racing and endurance horses may suffer from this on hot, humid days.

Working horses typically sweat profusely on hot days. As with humans, this is a natural means of self-cooling. If a horse fails to do so, this may be a sign of anhydrosis, particularly if he also seems to pant through his mouth.

If this occurs, it's time to call the veterinarian. Bathing the horse with cold water, especially around the head and neck, can provide quick relief and help reduce his body temperature.

DETER DEHYDRATION

Horses require plenty of water each day, especially in the summer months. Keeping buckets and water troughs filled with fresh water will prevent dehydration.

Test for dehydration by pinching a flap of skin on a horse's neck. If it immediately pops back into place, the horse is OK. If the flap holds for a few moments, that horse is in danger of dehydration.

LIGHTEN THE WORKLOAD

On truly oppressive hot days, a caring rider will not expect a full workout from his horse. Long warmup walks and even longer cool-outs will bracket an abbreviated work session. Following up with a cool hose-down and hand-walk are extra important!

PROVIDE SALT AND MINERALS

Sodium, electrolytes, and key minerals are essential to the health of active horses. Install a salt or mineral lick in each horse's stall. Offer mineral tubs in the pastures. These will provide important nutrients and also encourages horses to drink greater quantities of water.

PROTECT AGAINST FLIES AND PESTS

Lightweight, breathable flysheets may deter insects from biting your horse. At the same time, these may cool the horse from the sun. Select open-weave mesh fabrics, rather than tightly woven textiles, which can become dangerously hot.

Flysprays can help to keep flies off your horse, so he does not have to overexert on a hot day, just to keep the bugs away!

PROVIDE SHADE IN PASTURES

If pastures do not include shady areas, consider adding an open lean-to or run-in shelter. Horses may not use it often, but there may be occasions when they need to get out of the sunlight or elements.

KEEP STALLS CLEAN AND VENTILATED

If your horse is stabled, be sure to provide adequate air circulation. Open windows and barn doors. Remove soiled bedding, as this creates pungent fumes in the heat.

Adding a box fan to the stall bars can greatly improve ventilation and cool down the stall. (Be sure to unplug all fans before leaving the barn for the night, to avoid potential fire hazards.)

 


Weaning And Halter Breaking Your Foal

By Tina Lewis, MyEquineNetwork.com Contributing Writer


That time of year is here, once again, when we need to think about halter breaking the foal we waited nearly a year for. My Grandfather used to say, “there is more than one way to skin a cat,” so here is my take on having a smooth weaning and halter breaking experience.

Starting the halter breaking process before weaning is optimal, of course. One of the biggest reasons is that you can use the mare to get a halter on your foal for the first time by blocking the foal against the mare when it is young. Leading them to a smaller pen first, is helpful. With your left arm under his neck at his chest, use your right hand to grasp his tail at the dock as close to his buttocks as you can get. Lift it up in the air, firmly. We call this the “brake.” Once you have the foal in this position, keep him close to mom and he will usually remain fairly quiet while you have your helper put a halter on him. Make sure you are moving very quietly and slowly so he doesn't think you are going to hurt him. Doing this once or twice a day will get him used to being haltered, and he will be voluntarily sticking his nose into the halter before you know it. Use the mare while you can. If your mare is "nasty" you may want to wait to do the halter breaking until after weaning and wean a bit earlier. Once haltered, it is usually easiest to have a helper lead the mare while you "pretend" to lead your foal. He will actually be following his mom but getting the idea of leading and following you and getting used to the halter and the process of putting it on and off. Practice stops and starts using the voice commands "walk" and "whoa," but always let the foal go to his mom and stay near to her if he wants to. Make sure to have your helper stop and start the mare along with the foal if you want to be successful. He will not want to stop if his mom is continuing to walk away. The best time to play with your foal and get him used to you is while he feels safe next to his mom.

Ideally, a foal should be 4-6 months old and should be left in the pen, paddock or pasture that he has been used to and feels most comfortable in when the time comes to wean. It is best to leave the foal in familiar surroundings by pulling the mare out and leaving the foal behind instead of the other way around. A baby-sitter mare or gelding, preferably one that has been a pasture mate since birth, should be left with the foal or foals when the mare is removed. This leaves the foal with an adult horse he knows and trusts that will help protect and guide him. This first step to weaning your foal can make a potentially stressful day much less so. I try to never just remove a foal from its mother and leave it alone somewhere in a pen all alone. A little preparation can make all the difference in the world to the foal's level of stress on weaning day, as well as the stress of the mare and her owner.

Begin weaning by haltering up the mare or mares one at a time, “peeling” off her foal by leading the mare out of the gate and quickly turning her in the opposite direction of the gate opening. The foal will usually try to follow mom down the fence line rather than go out the gate behind her. The pasture or paddock must be sturdy and safe, as the foal will try to get to the mare. If your mare and foal have been kept in a smaller pen, rather than a pasture, you will want to have a buddy in a pen next to them for a while before weaning so your foal can become familiar to him or her by the time weaning day arrives. This will lessen the stress on the foal when mom is removed. I also suggest putting out some type of grain or foal feed, and free choice hay to take the foal’s mind off mom. This sometimes works to your advantage as the foal may get so busy eating he doesn't notice right away that you have taken mom away and wont be trying to push his way out of the gate behind her. Having more than one mare and foal to wean is helpful too as the foals comfort each other.

Move the mare, or mares, one at a time to the new pen or pasture preferably somewhere out of sight, and earshot so the mare and foal cannot see or hear each other. Second best would be out of sight, even if they can still hear each other's cries. If space is limited, you can just put a pen or pasture between them. Putting them in a pen or pasture right next to each other will allow nursing through the fence as well as create a much greater potential for injury. The mare and foal must be in safe and secure pens with strong and safe fencing. They will try to get to each other. Utilizing a friend's house works well in a pinch as they need only be out of eye and earshot for a few weeks to accomplish weaning.

Once the mare and foal are secure, they will cry for each other for a day or so. Try to keep both mare and foal comforted with extra hay and grain and lots of fresh water. Pacing and crying are normal and will subside. After the foal settles down, continue to feed a good quality grain designed for foals according to the directions on the bag of feed or your Veterinarians advice. It is important to feed grain in addition to hay for the first 2 years of life as they are growing at such a rapid rate during this time.


In the days following weaning, you should try to get the foal haltered up, led around, feet picked up, groomed, fly sprayed, bathed and de-wormed. Ask your Veterinarian which de-worming medication is right for your foal and meets the needs of your area and time of year you are weaning. You can also get an estimate from your veterinarian of the weight of your foal if you don’t own a weight tape. Weight tapes are usually available at your local feed store and are relatively inexpensive and a useful tool in making sure you don’t over (or under) dose your horses. Your veterinarian can also advise you on what to vaccinate your foal with and when is the best time to vaccinate for your area. We vaccinate and de-worm our mares just before foaling so as to give the foal antibodies in the colostrum when they are born, and then vaccinate our foals sometime between 6 and 9 months of age after they are weaned.

Once we have accomplished weaning we need to begin halter breaking with lots of touching and patting. Start out by approaching the foal down low at first, at eye level so as not to intimidate. Get down on one knee. Let the foal come to you. If the foal has not been handled at all, our first goal is to gain his trust so we can get a halter on and off with ease. You may need some help the first few times and a very small pen to corner him in so you can get the halter on. Remember to move slowly. A catch pen made from panels in the corner of a paddock or pasture works well using some grain and hay as bait to get the foal in it.

Once you have gotten the halter on, make it a pleasant experience so that each time is easier. Never leave a halter on a foal in a pasture or pen. The risk of it catching on something and causing serious injury or even death is far too great. It may be a little trouble to try to get it back on again but a foal learns quickly and, after all, that is what we are trying to teach them - to allow the halter to be put on and taken off. If you leave it on you are not teaching him anything. Besides, the trouble is well worth his life.

Once you have your foal haltering easily you should be leading him (or trying to) around your property beginning with a few baby steps. You may use a butt rope for a little impulsion from behind if you do not have a helper to keep him moving. Use a soft cotton lead, a non-slip knot and make a good sized loop that sits just on top of the hocks, over the buttocks at the point of the croup with the lead following along his back, down at the withers and then going under the throatlatch, through the halter under his chin and out along the lead rope that is attached to his halter. Use both the lead rope and the butt rope lead together allowing pressure from the front and the rear of the foal at the same time until the foal learns to give to the pressure from the front. You can then use just the lead rope attached to his halter and not the butt rope lead and remove it when you don't feel you need it any longer. Foals learn very quickly so this may only take a few minutes or it might take a couple of sessions.

Reward even a small step or two with a good boy and a pat. Use small, easy taps and don’t ever just pull on a weanling’s head. Not quick taps, but a firm, pull and release, pull and release. There should be a series of pulls and releases to encourage the foal to step toward you. Use the voice command, "walk". You may sometimes have to “unstick” those front feet by tapping to one side or the other instead of directly forward. If he takes one step either way you should stop and reward that by releasing the pressure (the taps) and patting and a saying, “good boy”. Not pulling in a steady pressure on the weanling’s head is one of the most important things to remember. Pulling causes the weanling to fight and try to find some sort of release from the pressure. He may begin to rear up. If he starts to rear and is about to flip over, use sharp taps and quick releases, not hard pulls, remembering to keep the head from hitting the ground (or anything else). Sometimes you cannot avoid the foal flipping over but keeping his head protected is first and foremost at that point. You can do this by keeping enough pressure (or putting it on) at the moment when it may hit the ground or any other obstacle with a sharp pull. Remaining calm and cool headed is very important because the weanling isn't going to be.

Keep training sessions short as his attention span is short and you want to keep it fun for him. Start with about five or ten minutes and increase that as he grows and learns. End each session on a good note. Unfasten, release the halter and walk away from him. Don't wait for him to run away from you or try to reach out and pet him (usually unsuccessfully) one last time. You must remain in control and keep his interest and his respect.

A broke, gentle and calm horse starts with good, solid groundwork. There is so much groundwork to be done before you toss that saddle on. Groundwork will prepare him for that day and for the day you take that first ride - which will be here before you know it.


Severe Weather Safety Tips


I know that we don't want to think about this possibility, however, here are a few tips from Ridecamp Archives that might help you out in a bad weather situation.
If a tornado is approaching your area what can you do to protect yourself and your horse? Get off and get low. Get in a ditch, culvert, behind a large fallen log, If you can detect the path of the tornado and you are in an open area; try to travel perpendicular to its path.
Hail can panic a horse. Get off!
Lightning: avoid being in open area. Thickly wooded trails are safer as long as you are not on top of a hill. Avoid hilltops in open meadows. Don't take shelter under a lone tree.
If you are caught in the open by a rapidly approaching lightning storm; get off, tie the horse if you can, but get away from your horse. You can get low; the horse can't. If you are holding the reins and the horse is struck by lightning the lightning can be conducted to you.


IS BAREFOOT BETTER???

BY JENNIFER FORSBERG MEYER

A growing contingent of hoof-care experts says yes. Here’s
what the natural-foot movement could mean for your horse.

THE BAREFOOT OPTION. YOU’VE HEARD OF IT, BUT YOU KNOW IT’S NOT
for your horse, because (pick one or more):
• it’s a fad.
• he has bad feet.
• you ride on rugged ground.
• you show.
You agree that going barefoot is healthy for a hoof, and that pulling a horse’s shoes
at least once a year to reestablish natural hoof growth is a good thing. But eventually
those shoes must go back on, right? Permanent barefootedness is appropriate only
for certain horses who already have tough, resilient hooves.
Right?
Four months ago, I’d have agreed with you on all of the above. But now I’m not
so sure. By researching this article, I’ve learned amazing things about how a horse’s
hoof is designed to function. As a result, I’m beginning to understand why a growing
number of natural hoof-care experts say barefoot is not just for horses with
already-excellent hooves.
In fact, judging by the evidence, the opposite may be true. Going barefoot (as the
result of a correct trim and combined with compatible living conditions) may be the
way to make bad hooves better, and even excellent. It may also create hooves capable
of supporting a horse—with rider—over most types of terrain.And (this is the most
intriguing part) it may enhance a horse’s overall health, comfort, and longevity.
What I learned, in fact, prompted me to consider the barefoot lifestyle for my own
horses, who live and are sometimes ridden on hard, rocky ground.
In this article, I’ll explain what I found so compelling. I’ll tell how the barefoot movement
began, share the thinking of some of its most prominent advocates, and detail
what’s necessary to make the barefoot option work. I’ll also discuss an alternative
approach that applies natural-foot principles to a nontraditional shoe.
In short, I’ll give you the tools you need to decide if new-age foot care is something you want to pursue for your own horse.

 

AS NATURE INTENDED
The foundation for a natural approach to hoof care was laid
20 years ago primarily by the work of two farriers. Jaime Jackson
and Gene Ovnicek independently conducted field
research among feral mustangs in the mid-1980s. Each hoped
to see what the hooves and habits of horses in the wild might
tell us about foot care for the domestic horse.
Both were astonished at the hardiness and resilience of the
feet they saw.Without metal shoes to restrict elasticity and
contact with the ground, the mustangs’ feet remained tough
and healthy even traveling at speed over the roughest ground.
Lameness was rare, and usually accident-related rather than
caused by disease of the hoof itself.
The mustangs’ feet were heavily callused across the toe.
Ovnicek’s research showed that, contrary to popular belief,
the hoof wall is not the primary weight-bearing surface.
Rather, the load is shared among the sole, bars, frog, and wall.
“Intuitively, it always seemed to make sense that the hoof
wall is the weight-bearer,” says Ovnicek today.“And that belief
kept us stuck in old modes of shoeing.”
In the 20 years since the first feral-horse research, interest
in natural methods of increasing the hoof health of domestic
horses has blossomed around the world. Jackson has gone
on to write several books related to the topic (see “To Learn
More,”on page 57).He also helped create the American Association
of Natural Hoof Care Practitioners, which promotes
research and trains/certifies professionals.
Ovnicek, who still supports the ideal of “barefoot where
possible,” has gone on to develop an innovative shoe that takes
the natural functioning of the equine foot into account.  He also lectures and
provides clinics around the world on what he calls the “natural
balance” of the equine foot.
Veterinarians, research centers, and universities are increasingly
taking notice of the natural hoof ’s powers to prevent
and in many cases cure diseases like laminitis and navicular.
Moreover, word of mouth among horse owners is building
demand for more information on natural hoof care and access
to practitioners.
Just before I began work on this article, I heard an enthusiastic
endorsement of the barefoot trim from my neighbor,
who’s pleased with the results she’s getting with her laminitic
gelding.That caused me to wonder: Just how does it all work?


THE UNDERLYING SCIENCE
Robert Bowker,VMD, PhD is a leading researcher in the natural
function of the equine foot. A neurobiologist who teaches
anatomy at Michigan State University, he became interested in foot function about 10 or 12 years ago, when students
asked him about the correct placement of nerve blocks. The
anatomy texts he checked were incorrect, so he began examining
the equine foot himself.
His research extended from the nerves of the foot to the
blood vessels, cartilage, and bones, and more recently to the
hooves and their laminae in health and disease.He supplemented
his lab work with observations of free-roaming feral horses.
What he found added momentum to the barefoot movement.
He discovered that the blood in horses’ feet does much
more than provide nutrients to hoof tissues. It also enables
the unshod foot to function as a hydraulic system, in much
the same way that gel-filled athletic shoes do.
“Moving liquids are the best way to dissipate energy,” Bowker
said in 1999,when his research was first publicized.“That’s
why some of the major running shoe manufacturers market
products that contain liquids in their soles.”
Bowker also discovered, however, that the blood isn’t forced
out of the foot upon impact, with the digital cushion—the
thick pad of elastic fiber at the heel—absorbing most of the
concussion, as was previously thought. Rather, as the
hoof expands upon landing, it creates a vacuum that sucks
blood from beneath the coffin bone into the rear portion of
the hoof. “As the blood moves through microvessels in the hoof cartilage,
it dissipates the energy caused by the impact on the
ground,” he explained at the time. “We need to be trimming
hooves so that more of the back part of the foot—including
the frog—bears the initial ground impact forces and weight.”
The problem, of course, is that traditional metal shoes not
only limit the expansion and contraction of the hoof, they
also raise the frog and heel off the ground. Bowker says today
that the difference between wearing shoes and going barefoot
is like the difference between working in high heels and wearing
sneakers.
“Horseshoes provide a much smaller surface area to absorb shock,” explains the researcher,whose own wife’s horse is now
happily barefoot.“So if a bare hoof landing after a jump experiences,
say, 1,000 pounds of loading per square foot, then
with a traditional shoe, there’s going to be 2,000 pounds per
square foot.”
The consequences of this are significant.With their natural
function compromised, key hoof structures become weak
through lack of use, thus more vulnerable to navicular syndrome
and other lamenesses. And, with the shock-absorbing
ability of the foot limited, the concussion travels up the horse’s
leg, stressing bones and joints.
It’s this latter phenomenon of how the wearing of shoes
affects the rest of the horse’s body that initially grabbed the
attention of yet another barefoot advocate, farrier Pete Ramey.


BAREFOOT IN ACTION
Now an instructor and clinician for the AANHCP and one
of the world’s most experienced natural hoof-care practitioners,
Ramey first learned about the potential advantages of barefootedness
in 1998. Intrigued, he pulled the shoes from his
own string of about 20 rental horses and was “blown away”
by what he saw.
“These were geriatric geldings, many over 30, averaging 20
miles a day over rocks,” he recalls. “Once their feet made the
transition, they functioned beautifully over that terrain. But
what really got me was how the geldings’ endurance increased,
and their ‘creaks and groans’ diminished. I began to have fewer
of them on the ‘injured reserve list.’”
Ramey points to the findings of Bowker’s research to explain
what was happening.
“Because the bare foot is such an effective blood pump, the
horse’s heart doesn’t have to work as hard. Endurance riders
have known this for a while—it’s why many of them use boots
instead of shoes: Their horses recover faster.” 

Then, too, there’s that superior cushioning of the bare foot,
which spares a horse’s joints, ligaments, and other tissues.
“It’s like the difference between a steel wheel and a rubber
tire,” he notes. “People assume it’s normal for horses to have
joint or back problems as they age, but it may be many of these
aches are caused by the increased stresses of wearing shoes.”
Ramey strongly disagrees with those who say shoes are necessary
because we’ve “bred the foot off ” the modern horse.
“It’s just not true. Unless there’s a bone pathology, virtually
any horse can grow a healthy foot, given time and proper
trimming.”
Although the exact specifications of that trim are still
evolving, most natural-foot practitioners agree that the
result should enable the sole, the bars, the frog, and the walls
to share the load. Only exfoliating material should be
trimmed from the sole and frog, allowing thick calluses to
develop over these structures. The outer hoof wall is best
beveled to minimize flaring and separation. Sometimes
called a “mustang roll,” this beveling mimics the wear pattern
on feral horses’ feet. (Note: The experts I spoke with
for this article agreed that the Strasser trim, developed by
German veterinarian Hiltrud Strasser, is invasive and
should be avoided.)
To ease the transition from shod to barefoot, Ramey and
other practitioners recommend hoof boots, often helping
their clients select and fit them. Because of the increasing
demand for boots from owners of barefoot horses, a wealth
of styles and models is now appearing on the market.
“Boots provide protection while a horse’s hoof is remodeling
and becoming tougher,” says Ramey. “They’re the 21st
century ‘shoe,’protecting a foot as well as the ‘old school’metal
shoe, only supporting hoof health rather than degrading it.
Over time, as the feet develop their natural resilience, the
boots are no longer necessary for most riding.”


NATURAL FOOT, NATURAL HORSE
Most natural hoof care practitioners agree that a barefoot trim
works best on a horse living a more natural lifestyle, including
as much turnout as feasible. Ideally, the horse should live
on the same type of ground he’ll be ridden on. For example,
if you ordinarily ride a lot on rough trails, your barefoot
horse is best turned out on terrain that includes rocks and
hard footing.
“It’s something the AANHCP and the barefoot movement
in general are working towards now,” says Mark Jeldness, a
field instructor for the association. “We want to help owners
find ways to create the right kind of environment for their
horses, and to encourage their horses to move around on it
as much as possible.”
For owners who can’t provide enough turnout, keeping the
horse well exercised under saddle during the transition period
is critical. Boots make this possible, as well as frequent
trims (every four to six weeks) that encourage the foot to
remodel properly.
In that this approach to foot care fits within the natural-isbetter
movement at large, it’s not surprising that natural horsemanship
clinicians are embracing the no-shoes option more
readily than are mainstream trainers. John Lyons hasn’t shod his

horses in 10 years, but he believes owners must use common
sense when considering what to do with their own horses.
“You don’t need shoes just because you ride a horse, and
leaving shoes off is ideal for forming a healthier, stronger
foot,” he maintains. “I put gravel in my pastures where the
horses walk to help toughen their feet. But you have to use
common sense, too. If I were roping all the time in a sand
arena, I’d probably use shoes.”
Clinton Anderson quit using traditional shoeing a year and
a half ago, and now puts hind shoes only on his reiners.
“You do need the shoes in back to be able to slide,” he says.
“But other than that,with the right trimming, there’s no reason
to shoe. The feet don’t change overnight—I’ve found it
takes anywhere from six months to a year for them to fully
make the transition—but when they do, they get hard and
strong and tough enough for most any kind of riding.”
Of course, not everyone agrees this is so, and there are
any number of traditional farriers and longtime horsemen
who’ll tell you the “barefoot thing” is misguided, plain and
simple. But one undeniable strength of the natural hoof care
movement is its emphasis on maximizing the health potential
of every foot.
“The key difference between traditional farrier care and
the barefoot approach is that we’re zoomed in on figuring out
how to make all horses grow good feet,” says Ramey. “A vet I
work with told me recently he used to look at a horse with
bad hooves and say, ‘Wow—that horse has awful feet.’ Now
he says, ‘Wow—that horse could have good feet if we do this
and this and this.’ It’s a significant difference.”
For my part, I’m impressed enough with the underlying
science and the case histories to give barefoot a try. My
horses received a natural trim from an AANHCP-certified
practitioner last December, and are spending several months
turned out in an area with varied terrain.When my daughter
and I resume riding,we’ll use boots if necessary until their
feet are sufficiently remodeled.
At the end of the transition period, the worst-case scenario
is that our horses will have much healthier hooves on which
to nail shoes. And if they wind up happy without their shoes, even better.

 


 BAD THINGS "GOOD" DRUGS DO
By Tanya Randal

Money and competition may alter people’s priorities when it comes to their horses’ wellbeing.
So says veterinarian Kim A. Sprayberry, a diplomat of the American College of Veterinary Internal Medicine. Never is this more evident than in situations involving competitive events and the administration of drugs that we give our horses to get through a show or a tough weekend.
While some drugs are illegal, it’s most often the everyday drugs –bute, Banamine,® and dexamethasone – that are responsible for the numerous syringes found littering the stall areas at major events.

The problem is not necessarily with the drugs, per se, but rather with the manner in which they are used and misused. All drugs have side effects that accompany their intended effects; therefore, even good drugs do bad things when used inappropriately. Dr. Sprayberry, Chicago, Ill., has seventeen years of practice under her belt. Six years were spent on the racetrack and three as an associate internal medicine specialist at Haygard Davidson McGee, Associates, in Lexington, Ky. She spent four years consulting as an internal medicine specialist in California and currently as an assistant editor at the American Journal of Veterinary Research and Journal of The American Veterinary Medical Association. Sprayberry knows firsthand the bad things “good” drugs do.

Non-Steroidal Anti-inflammatory Drugs (NSAIDs) NSAIDs are probably the most commonly used drugs in the horse world. They are used to treat inflammation and pain. Flunixin meglumine, more commonly referred to by its brand name Banamine®, and phenylbutazone, or “bute,” are found in nearly every tack room. Unfortunately, they are the most commonly abused drugs as well.

The most talked about side effect of NSAID use are the development of gastric ulcers. Many people erroneously assume that it’s only the oral ingested forms of NSAIDs, the powders and pastes, which cause the problem. Unfortunately having NSAIDs actually go through a horse’s gastrointestinal (GI) tract isn’t the problem. It’s the very job of NSAIDs that causes the problem. “The way they all work is to interrupt the cascades that generate prostaglandins,” said Sprayberry. Prostaglandins are naturally occurring chemicals that stimulate smooth muscle responses in the body. NSAIDs, she explains, are all cyclooxygenase (COX) inhibitors. COX produces prostaglandins, which mediate the sensation of pain.

When an injury is hurting a horse, the natural response is for prostaglandins to foster pain and inflammation so that the horse will stop doing what’s causing the pain and allow the body to heal.
However, not all prostaglandins cause inflammation. Other such as prostaglandin E (PGE) and prostaglandin I (PGI) are beneficial to the body in important ways. Sprayberry calls PGE and PGI the quiet little housekeeping prostaglandins, meaning they are always active at low levels in the background. They are the ones responsible for keeping the blood vessels open to the kidneys and stomach mucosa.

NSAIDs interrupt PGE and PGI production, leading to the development of gastric ulcers and kidney problems. “They stop generation of the inflammatory prostaglandins, but they also prevent production of the ones that are doing good things for you in the background,” she said. With stomach ulcer formation, Sprayberry explained, “As soon as the stomach mucosa has had its blood supply decreased even for a few hours, you can get ulcers. The blood supply keeps the stomach producing mucus and buffers that protects the stomach lining from back diffusion of acid. If you decrease that blood supply, the mucus barrier erodes, and the acid produced by the cells of the stomach bathes that lining and burns ulcers into the surface.”

In fact, one of the treatments for severe ulcers, from any cause, is to add prostaglandins back into the body through the use of such drugs as misoprostol. PGE and PGI become especially important when a horse gets dehydrated. “The physiologic response to dehydration is to shut down certain vascular beds and to shunt the blood flow to the most important areas of the body at the moment,” she explained. “The organs in which blood supply is most affected in those circumstances include the kidneys and stomach. Nature in effect says that “digestion and urine production will have to wait until we get through this dehydration period.”

In a dehydrated horse, PGE and PGI keep the blood vessels in the stomach lining and the kidneys open at least a little bit, so that those organs do not get damaged. However, if you give a dehydrated horse bute or Banamine,® the housekeeping prostaglandins are decreased along with the inflammatory prostaglandins and can’t perform their protective functions, and the organs are insulted.
“The horse that is dripping wet with sweat or that hasn’t been drinking shouldn’t be given bute or Banamine®,” Sprayberry said. “Wait until it drinks some water and has a belly full of hay before administering, if the drug is needed. When the horse is wringing wet and uncomfortable is often when people want to give it, and that’s when you should expressly not.”

Another less-common but extremely dangerous side effect is right dorsal colitis (RDC), which is an ulcerative inflammatory disorder of the colon. Sprayberry said RDC can be both a life-threatening and chronic problem. Horses with acute RDC suffer from colic, diarrhea, dehydration, and endotoxic shock. Chronic RDC is marked by intermittent colic and weight loss with or without the presence of diarrhea. The treatment of RDC can be extremely difficult and only modestly effective. In some cases, the affected length of colon can never be restored to health and must be removed surgically to save the horse.

Another problem that arises with bute and Banamine® administration are problems stemming from the injection process itself. Bute should never be administered in the muscle or subcutaneously (right under the skin). It causes irritation, swelling, and necrosis (localized death) and sloughing of tissues. Manufacturers recommend injectable bute only be given in a vein and then for no more than five consecutive days before switching to an oral form. These effects occur because of the formulation of the solution, causing it to be caustic to tissue and the vein walls. Damage or insult to the vein wall is called phlebitis; inflammation of a vein wall that causes damage and clotting.”
For oral bute, (paste, powder, or tablets) no more than four grams should be given in a single day.
Problems associated with giving Banamine® intramuscularly are swelling and stiffness, but these problems are generally transient and do not require attention. Although in some cases serious inflammation and muscle damage can occur.

Bute and Banamine® solutions cannot be mixed together, and probably should not be administered at the same time, anyway. Because the two drugs act on the same enzyme systems, one or the other should be chosen for a given horse in a given situation. The therapeutic dose range of bute is such that no more than four grams should be given per day. “If four grams has not had a demonstrable effect, neither will 6 grams,” Sprayberry says. “What is needed is a different kind of medication, not more of the same.”

With certain types of injuries, topical NSAIDs (products such as Surpass®), are rapidly becoming the treatment of choice because systematic problems, such as ulcers, are avoided. There are also NSAIDs that target production of the anti-inflammatory prostaglandins while leaving production of the ‘housekeeping’ prostaglandins unaffected. Nevertheless, the effects are relative, and all NSAID drugs can still lead to the development of ulcers and the other problems discussed. Regarding topical formulations, “You get very high local concentrations without the systemic effects,” Sprayberry said. She cautioned that problems can still occur if topical NSAIDs are misused. They should be used according to label instructions, period.

Oftentimes that judgment call is the difference between allowing a horse to tell you it’s too sore to compete If a horse is continually performing on NSAIDs, how can it signal the rider that a potential problem is developing? Once these horses are “head-bobbing” lame or not performing well even will on medication, injuries are fully developed or have reached the chronic, more difficult-to-treat stage.
. The bottom line, according to Sprayberry, is NSAIDs “should not be given indiscriminately.”
“The problem is that owners are the decision maker for the horse,” said Sprayberry. “Competition and the lure of success or prize money can get in the way of purity of judgment, and I think we should be fair to the horse who gives us everything. The sport should be fun and ultimately safe for its main participant, too.”

Corticosteroids
Corticosteroids, sometimes called glucocorticioids, are steroids closely related to cortisol, a hormone produced naturally by the body in response to stress. The corticosteroids most competitors are familiar with are those used intraarticularly (injected into the joint), including methylprenisolone acetate (Depo-medrol®) and Triamcinolone acetate (Vetalog®). Another commonly used corticosteroid for treating allergic reactions is dexamethasone (Azuim®).

“Corticosteriods are useful drugs, potent anti-inflammatories,” Sprayberry said. “When used properly, they can bring a horse great relief, whether they’re given orally, by intravenous or intramuscular injection, or in the joint. But they should be combined with a period of rest so the body can heal as the painful condition is being controlled with the drugs.”

Depo-medrol® is the most powerful and long-lasting corticosteroid used in joint injections. Many times people erroneously call it cortisone, because it’s the steroid that most people are familiar with because we use it topically to treat wounds and rashes. Depo-medrol® is commonly used to inject the lower, ‘slide-and-glide joints’ of the hock.

A major drawback is that frequent injections of Depo-medrol® can damage cartilage. This is often considered an acceptable risk in the lower hock joint because a horse can compete with these joints fused, and even then most performance horses are injected with a combination of intraarticular hyluronic acid and Depo-medrol®. However, it’s been noted by many orthopedic veterinary specialists that high-motion joints such as fetlocks, knees, and stifles don’t fare as well with multiple injections of Depo-medrol.® Triamcinolone acetae (Vetalog®) is more commonly used in high-motion joints because it is less damaging to cartilage. It may also have cartilage-protecting properties. Unfortunately, Vetalog® isn’t as potent as Depo-medrol®.

“It’s not wrong to put steroids into a horse’s joints,” Sprayberry said. “They have beneficial effects, for sure. Their finest use is when you inject the joint following a proper diagnosis for the lameness and then combine the drug administration with some time off for the horse. The drugs are potently anti-inflammatory; if you combine that effect with a period of enforced rest so that new damage can actually be repaired, that’s the best use of those drugs. Chronic, ongoing joint degeneration is a different situation, and in those cases, once again, good judgment among the owner-veterinarian team should be used.”

Tranquilizers
Acepromazine maleate, better known simply as “ace,” is one the most common tranquilizers used in horses. Cutters and reiners often used by barrel racers to “take the edge off” a fractious or hyper horses in competition. It can also be used as a preventive measure against exertional rhyabdomyolysis, the medical term for tying up, because it lowers blood pressure by opening up small blood vessels. While it may help prevent the horse from mowing people down in the warm-up pen, the drop in blood pressure it causes can hamper athletic performance. Another serious drawback to ace use during competition is that it increases the strains on tendons and ligaments since it relaxes muscles. “It decreases their blood pressure,” Sprayberry said. “Although horses cannot describe how that makes them feel, it is fair to imagine that it would be similar to you feeling really dizzy and being made to go out and run, which is the last thing in the world that you would feel like doing. It make take your nervous edge off, but you are far from feeling right.” And acepromazine is not without potentially harmful side effects. Although rare, its most concerning side effect is penile paralysis in stallions and geldings. For this reason it should be avoided at all costs in breeding stallions. “The risk might be low,” Sprayberry said, “but the consequences are permanent.”

Fluphenazine is another popular tranquilizer. “It’s another drug that some people find useful for a high-strung horse that wants to wash out or is so excitable that it can’t be trained,” Sprayberry said. “The drug is a phenothiazine compound, just like acepromazine, but it is not labeled for use in horses at all. It may not cause the decrease in blood pressure that ace does, but the side effects of fluphenazine can be horrific and long-lasting. “Administration of fluphenazine also may cause some ‘extrapyramidal’ effects, referring to the parts of the brain that are affected. They enter an excitatory, manic phase where they bounce off of or try to climb the walls. They are, in essence, uncontrollable. They must be left in a dark stall with a protective helmet on and, in some instances, left there until the effect wears off. Sometimes this has taken weeks.” 

 Second opinion on this drug from another source.   Fluphenazine Reactions in Horses 8/8/06

In the equine show horse and performance horse industry, many drugs are given that are unapproved of for use in horses.  Many equine groups require drug testing of horses, which limits the use of these drugs.  However, a large number of associations do not require any testing.  Although it is unethical to use these drugs in my opinion, most of the time the horses are not harmed and there is not a fear of human safety.  One of the most commonly used drugs is fluphenazine and horse owners may be using this drug in their horses and not know the concerns with it.  Fluphenazine is a highly potent drug used in people for the treatment of schizophrenia and other forms of psychotic illness.  A long-acting form of the drug is used in horses as a long-term sedative and is considered by the United States Equestrian Federation as a forbidden substance. 

The drug was initially used in horses who had an injury that required the horse to be stalled for long periods of time and needed to be sedated until the injury healed.  However, the drug is now mostly used in performance horses that are a little too excitable and are somewhat uncontrollable.  The ethical problem with this is that the best horse and rider may not win the competition.  However, there is also a safety problem.  A recent report described four horses with severe behavioral abnormalities consistent with parkinsonism.  Clinically these horses developed profuse sweating, agitation, intense pawing, striking out with the forelegs, and uncontrolled swinging of the head.  Three of the four horses recovered following intensive care, but one died.  Not only can the horses die, but any humans around these horses when they develop this violent behavior could also be severely injured www.veterinarypartner.com

Sprayberry acknowledges the benefits of tranquilizers. She pointed to a recent study that showed that horses given acepromazine could still learn. “Studies show that horses retain their ability to learn while on normal doses of the drug,” she said. “Again, it is a question of degrees. If tranquilizing a horse gets you through a certain training episode or helps get a refractory horse into a trailer, we can say it was helpful. If you have to keep giving it, I think you have to ask yourself if the horse suited for the job. If a horse needs long-acting tranquilizers or repeated tranquilization, you should think about what you’re asking it to do. Tranquilization isn’t a substitute for remedial training, which is really the answer. Horses that persist in nervousness severe enough to require tranquilization probably don’t have an affinity for the job they’re being asked to perform.”

Judicious use
It’s not wrong to use these drugs, Sprayberry said, but it’s wrong to abuse them. However, what is considered judicious use of these drugs varies from owner to owner, from veterinarian to veterinarian, and from situation to situation.
Sprayberry used the example of a high school rodeo cutting horse diagnosed with navicular disease when Nationals are right around the corner.
“His young rider needs to get through the finals,” Sprayberry elaborates. “She’s been competing all year. The horse likes to go. Is it wrong to inject his joints and give him some bute to show him? That’s the question, and I don’t know what the answer is. There are no easy answers. That’s why we have the problems. I do know that horses will give and give to humans beyond the point of their own detriment. It is the right thing to do, therefore, to keep their best interest factored into our decision-making. That includes what may happen to them down the road when they are eight years old and crippled.”

Not so Fun in the Sun: Equine Summer Skin Diseases


By T.A. Banner DVM

Summer sun and humidity can increase the risk of three common skin conditions;
know how to prevent them and identify the warning signs.


It's that time of year again when all the flies, mosquitoes and gnats decide to turn your quiet evenings into a swatfest and send you running for the house. Unfortunately for your horse, living in the great outdoors can mean dealing with environmental and insect issues 24 hours a day in the humid Southeastern climate. Horses are at increased risk for skin conditions in the summer season. Probably the biggest take home message I can give you is to start the appropriate treatment as recommended by your veterinarian as soon as a skin condition starts. Don't wait until the condition has worsened to the point of hair loss, skin lesions and your horse has knocked over half the fence posts in the paddock trying to scratch. Photosensitization, rain rot (dermatophilosis), and equine insect hypersensitivity are three common skin diseases. It is important to know the clinical signs and causes of each.

Photosensitization

Increasing day length brings increasing time under the hot sun. Photosensitization is a common problem in horses with pink or non-pigmented skin that is overexposed to sunlight. The most common areas affected are the face, nose and ears. In the summer, the intense rays of the sun will cause the skin to burn and cause peeling of the outer layers of epidermis. The skin is characterized by redness, localized swelling, sensitivity to the touch and could have weeping of serum. Photosensitization is believed to be caused by phylloerythrin, which is a normal breakdown product of chlorophyll in plants. The horse's liver is responsible for excreting phylloerythrin and any other plant chemicals that may ultimately damage the skin. Certain plants, such as ragwort, St. John's wort and buckwheat, contain chemicals that can damage the horse's liver. This will cause the skin to be more susceptible to ultraviolet rays from the sun.


Some medications, such as tetracylines, can make horses photosensitive. A pink-skinned horse in strong sun is likely to suffer from sunburn; but if that horse were being treated with photosensitizing medications, it could suffer from a more severe sunburn. There is a correlation between sunburn and liver damage with some systemic diseases involving the liver making horses more photosensitive. The best solution is to limit the skin's exposure to direct sunlight but sometimes that is not possible. The use of sun protection products is often necessary to keep the harmful rays from burning sensitive areas. Many of today's grooming products such as shampoos, fly sprays and coat conditioners may contain sunscreens, and the protection provided by a sun block such as zinc oxide is helpful. One of the problems is keeping it on the horse because grazing and horseplay can wipe the product from horse's face. The colored sun blocks may aid in determining when it is time to reapply the product when viewing from a distance.


Dermatophilosis

Dermatophilosis, "rain rot," "rain scald" or "streptothricosis" is a skin disease usually noted in prolonged wet conditions where high temperature and high humidity are present. Skin lesions usually appear as crust-like scabs or small 1/4 inch matted tufts of hair over the rump and back, but can affect much of the body. When rain rot appears on the lower limbs it is most commonly referred to as "dew poisoning."

The organism, dermatophilus congolensis, which causes rain rot, is not a fungus. It is an actinomycete which has the characteristics of both bacteria and fungi. It enters the follicle of the hair shaft and initially causes small lumps on the skin or hair when running your hand over your horse's coat. There are usually dozens of tiny scabs that contain embedded hair and can be pulled or rubbed off. Underneath the scabs, the skin is usually pink with yellowish pus at the skin surface. The organism damages the root and causes the entire hair shaft to lift out in small clumps leaving the area hairless.


Dermatophilosis, also known as rain rot, rain scald or streptothricosis is common in the Southeast due to increased humidity and high temperatures combined with rainfall. Photo courtesey of T.A. Banner, DVM.

The affected areas are often quite sensitive and saddles and other tack must be carefully used. Since the area becomes hairless then sun blocking products should be used to prevent sunburn. The organism can be spread through sharing of equipment between horses. This includes saddle pads, blankets, leg wraps, brushes, halters, etc. It is extremely difficult to prevent the spread of rain rot, since a horse can pass it to another horse by simply rubbing its skin on any object that the other horse may touch.

The best prevention for rain rot is to use a disinfectant on any equipment shared between horses after each use. Dermatophilus congolensis grows better with a lack of oxygen. Therefore, if your horse has a long, thick hair coat, it will be necessary to body clip the horse and remove any scabs that hold the organism to the horse's skin. It is not a good idea to use ointments on rain rot, because they hold moisture to the skin (and moisture needs to be removed for the condition to cease). The best treatment is to wash the horse with antimicrobial and antibacterial shampoos and rinses.

Culicoides Insect Hypersensitivity

Culicoides Insect Hypersensitivity (CIH) is known by many different names throughout the world (Sweet Itch, summer eczema, Summer Seasonal Recurrent Dermatitis (SSRD), Queensland Itch in Australia, Kasen in Japan and elsewhere as dhobie itch), the symptoms are the same.

Culicoides Insect Hypersensitivity is a condition that affects the quality of life of thousands of horses. CIH is an allergic skin disease affecting susceptible horses and ponies that become hypersensitive to the bites of the insect of the genus Culicoides. The tiny insects are commonly known as "biting midges," "punkies," or "no-see-ums" and are primarily active between March and October, during the early morning and the evening. Some sources report 120 or even 800 different Culicoides species. Culicoides are very small and can pass through conventional mosquito netting. They breed in aquatic habitats, decaying vegetation, manure or water troughs.

They feed on the horse at specific sites, usually around the tail head, under the mane, and underneath the horse's abdomen. The allergic reaction, caused by the saliva, develops at the site of feeding and the majority of affected horses show skin lesions affecting the mane, tail, face and ventral midline. The problem is characterized by intense itching (pruritus), which results in rubbing and considerable self-trauma, sometimes with secondary infection. Affected animals are itchy, causing intense rubbing and scratching on any available surface. Prolonged rubbing results in crusting, scaling, skin thickening, hair loss and damage to the skin. Mane and tail hairs may be broken and irregular due to repeated trauma.

The symptoms are yellowish spots approx. 50 - 150 millimeters in size, in many cases scratched open by the animals until bleeding occurs. Crusts are formed, the mane and tail hair being scratched and/or bitten away. In the crest, hardened spots can appear and burst open which give it a saw-like appearance. In the face, the hair sometimes is scratched away and the black skin underneath becomes visible.

CIH is not contagious but other, healthy animals in the herd might be affected as well because a horse with CIH will scratch harder into the withers of a healthy animal due to his own strong itch sensation and will in this way do some damage to the other's skin and hair. History and clinical cases among related horses give significant evidence of a hereditary factor. It usually affects younger horses but horses have been known to begin clinical signs in their 20's.

Control of the condition is often difficult, with the primary efforts directed at preventing affected horses and ponies from being bitten, and symptomatic treatment to control the irritating effects of the allergy. Your veterinarian may also be able to do a blood test to evaluate for CIH as well as other insect and environmental allergies.

As you can see there are many potential skin diseases in the horse and several more that were not discussed in this article. Living in a Southern tropical climate exposes our horses to continuous challenges from insects and environmental concerns. Remember to watch for early warning signs of any changes in the skin of your horse, and when noted, treat accordingly. It is also a good precaution when buying horses in the winter to ask about skin problems that could have been a problem the previous summer. You can assume that a problem last year will most likely be a problem this year.

The areas of the horse that are most affected by CIH are the tail and mane but the ears, poll, face, chest and ventral abdomen may also be involved.


CIH Prevention Tips
1) Spray and wipe down horse with insect repellents, especially in the early morning and late afternoon.

2) Install a fan or be sure that your stall has plenty of airflow since the small culicoides are not strong fliers.

3) Keep affected horses stalled in the barn from 6pm to 8am to reduce exposure as culicoides are most active at dusk and dawn.

4) Enclose the stall with a fine screen to prevent the entrance of the insects into the area.

5) Cover affected horses with a "fly sheet" and "fly mask" to prevent new bites.


 

Don't confuse Gnats with Biting Midges


Chironomid Midges
Richard M. Houseman
Urban Entomology Extension Specialist
Chironomid midges (gnats) are small flies that range in size from 1/16 to 1/2 inch long. They range in color from light tan to light green to nearly black, depending on the species. Midges can be confused with mosquitoes, which are similar in size, appearance and habitat; however, midges are distinctly different from mosquitoes in their feeding habits. Mosquitoes possess a long, beaklike mouthpart that is used to suck blood, whereas most midges do not even feed as adults and never take a blood meal. In addition, midges typically have “fuzzy” antenna, a characteristic found, to a lesser extent, only in male mosquitoes.

Large numbers of adult midges emerge at sundown, gather in swarms and produce a humming sound that can be heard several feet away. Adult midges are attracted to lights, which is the reason they are often found near human structures. When abundant, they are capable of completely covering areas of the home and other objects near lights. Several different species live and develop in a single body of water, and most of these species produce more than one generation per year. In some locations, the result can be almost nightly swarms, one after another, throughout the summer months. Some midge species are small enough to go through ordinary window screens and infest indoor areas.


Biting midge

(actual size approximately 1.5 millimeter).


Biting midges, also called punkies or no-see-ums, are tiny (about 1.5 mm long) flies of the family Ceratopogonidae (Figure 3). They have piercing-sucking mouthparts and attack almost any warm-blooded animal in search of a blood meal.

The bites of most species cause an immediate sharp pain. This is followed by the development of red areas. For most people these lesions last up to a week or more and are more painful than mosquito bites.

The larval stage of biting midges is wormlike and develops in standing water, wet soil, or wet organic matter. It takes about a month to complete development from egg to adult. Because of the aquatic or semiaquatic habitat of the larvae, adults are more likely to be a biting problem in areas near wet environments. Most biting activity takes place at twilight. Only the female midge is a blood feeder; the male feeds on plant juices.

Control
Effective control is difficult. Whenever possible, eliminate the wet conditions of the larval habitat. Area fogging and spraying offers little control and only brief relief. The best protection is the use of an insect repellent containing the active ingredient diethyl toluamide (DEET).


  Homemade Fly Spray Recipes


These home made fly spray recipes are gathered from around the web. Please research and use your own judgment and always check with your vet when in doubt.  I personally have not yet tried any of these so let me know if you have any sucess with them.

Special note: Whenever a fly spray recipe calls for citronella, you should use 100 percent pure citronella oil. It is a plant based product. You should not use citronella oil that is sold for an outdoor torch. That type of oil is petroleum based with a citronella smell. You can buy pure citronella oil at Cedar Vale online. Cedar Vale also has the other essential oils listed in the fly spray recipes below.

I used a variation of the fly sprays:
6 caps full of Skin so Soft
1 cup white vinegar
just a good squirt of Ivory liquid soap
filled a 32 oz Bronco Spray bottle with water
Sprayed it on the horses legs, Flies fell DEAD !!! 

Reminder - Consult your vet and use at your own risk.

1 cup vinegar
1 cup baby oil
1/4 cup original pinesol
1 tbs dish soap
1 tbs skin so soft
1 cup water

Reminder - Consult your vet and use at your own risk.

I used a mixture of half Pinesol and half water.I used it all year last year and it worked wonderful. My horses were never bothered with flies or knats and their coats were shiney.

4 oz Skin So Soft
1 oz citronella oil
12 oz vinegar
12 oz water

Mix all together and it lasts as long as any of the expensive ones do and smells a ton better! It is also good for their coat.

U.S. Forest Service Bug Spray Recipe

1 cup water
1 cup Avon Skin So Soft Bath Oil
2 cups vinegar
1 tbs. Eucalyptus oil (found in health food stores)
Optional: few tablespoons of citronella oil.

Shake spray bottle well before spraying on horse, human or dog!

BEST FLY REPELLANT -

submitted by Brianne

Made by Shaklee (remember them?)- BASIC H. It works. You can use it to spray areas where flies breed or congregate, once they have been misted, they can’t fly anymore and die. They hate it, and will not bother or bite horses who have been sprayed with it. You can make a diluted spray with 5-7 parts water and one part basic H . You can adjust the mixture to suit your area, but trust me, that concentration is plenty strong. You can also use to bathe your horses, yourself and your tack too. PH is in the range of human and horse skin, so it is great for sensitive skinned horses and people. No yucky smell either. Try it once and you will NEVER buy another fly repellent .

You can purchase off the Shaklee website, or from a member or distributor. The price is great too. Buy a gallon and imagine how far it goes- makes about 7 gallons of fly spray and will cost you about 30$. Great price, great product. I began using it at the stables where I board, and the whole stable was using it within the month, and continues to use it even after I brought my horses home.

Citrus Insect Repellant Spray
2 cups light mineral oil
1/2 cup lemon juice
2 tsp. citronella oil
2 tsp. eucalyptus essential oil
2 tsp. lemon dish soap

Combine all ingredients in a spray bottle. Label. To use gently shake and spray on your horse avoiding his eyes. NOTE: Do not use this spray before a show as it attracts dust.


Quick Fly Spray
18 oz white vinegar
2 Tbsp dish washing soap.
Mix in a 20 oz spray bottle and shake gently until well blended. You may add water to dilute. Spray liberally on your horse


Avon Skin So Soft
Mix 3 parts water to 1 part Avon's skin-so-soft in a spray bottle.
Spray liberally on your horse. This also softens his coat.


I have used this mix for years, and it works great. Laurie LaSalle, Rockin' Tree Ranch

Fly Repellent

2 cups white vinegar
1 cup Avon Skin So Soft (Bath oil)
1 cup water
1 tablespoon eucalyptus oil

Fly Control

An easy do it yourself fly spray that is relatively inexpensive, and I'm
told it really works! This spray attracts dust. So don't use it before
a show.

500m. (2 cups) light mineral oil
125ml (1/2 cup) lemon juice
10ml (2 tsp.) citronella oil
10ml eucalyptus oil
10ml lemon dish detergent
optional 125ml glycerin
Mix in a spray bottle and spray away!

Horse Insect Repellent Mix

1 oz. Citronella Oil
2 oz. Skin-So-Soft or Coat-So-Soft
1 Cup Cider Vinegar
1 cup Water

Mix in a 20 oz. spray bottle.

Internal Fly Repellant

If your horse is allergic to fly bites, try 1/4 cup of apple cider
vinegar on their grain once a day. This raises the blood acid level
just enough to bother the flies, but it is completely healthy for the
horse. It takes about one week to start seeing the effects. Several
old timers have told me that they always put vinegar in their horse's
drinking water during the summer to repel flies and mosquitoes.

Easy Fly Spray

You can mix seven parts water with one part citronella as a fly spray. It's not oily either. Mix it four parts water to one part citronella during the worst of the fly season.


You can take a bottle and fill it with white vinegar and two tablespoons of dish soap. Add water if you wish to dilute it a little. Shake and spray it on for a nice and very cheap fly spray. Debbi Delva

A golf course near my home passes out Bounce fabric softener sheets to the golfers to repel insects. Next time you go riding tie one to your Horse's headstall and stick one in your back pocket. It works better than ANY fly spray I've ever tried. The flies won't even fly around you. Susan Cafouras

I was given this recipe and it does work!!!!

15 oz water
5 oz commercial fly spray ( any brand)
5 oz vinegar
2 oz vegetable oil
2 oz green Dawn dish soap

Mix and use. All natural and will not harm coat.

One Ingredient Fly Spray

Pour six caps full of Skin-So-Soft in a 20 ounce spray bottle, and fill the rest with water. Shake and spray. Sien Creytens


Fly relief

If anyone has problems with flies in the barn, try filling a quart jar with this mixture.

3 cups of water
¼ (one quarter) cup sugar
¼ (one quarter) cup white vinegar

Mix, punch holes in the lid, and set it where needed. It works great. Toni Auen

For cheap fly repellent, mix about 1 1/2 cups of plain white vinegar into about every 75 gallons of water in your horse's water tub. If you use this it in the water about a week before flies start biting, it will have circulated in your horse and it helps keep flies from biting. -Lindsey


Euthanasia...What makes the grief process so complicated?

Sorrow and grief are normal, natural responses to death


The stages of grief
There are many stages of grief, and not everyone experiences them all or in the same order. You may experience denial, anger, guilt, depression, and acceptance and resolution. Your first reaction may be denial—denial that your horse has died or that death is imminent. Denial may begin when you first learn the seriousness of your horse’s illness or injuries. Often, the more sudden the death, the more difficult the loss is to accept.

 

Anger and guilt often follow denial. Your anger may be directed toward people you normally love and respect, including your family and your veterinarian. People coping with death will often say things that they do not really mean, perhaps hurting those whom they do not mean to hurt. You may feel guilty or blame others for not recognizing the illness earlier, for not doing something sooner, for not being able to afford other types of or further treatment, or for being careless and allowing the horse to be injured.

 

Depression is also part of the range of emotions experienced after the death of a special animal. The tears flow, there are knots in your stomach, and you are drained of all your energy. Day-to-day tasks can seem impossible to perform. Sometimes you may even ask yourself if you can go on without your horse. The answer is yes, but there are times when special assistance may be helpful in dealing with your loss.

 

Eventually, you will come to terms with your feelings. You can begin to resolve and accept your horse’s death. Even when you have reached resolution and acceptance, feelings of anger, denial, guilt, and depression may reappear. If this does happen, these feelings will usually be less intense, and with time will be replaced with fond memories.


Although the stages of grief apply fairly universally, grieving is always a personal process. Some people take longer than others to come to terms with denial, anger, guilt, and depression, and each loss is different. If you understand that these are normal reactions, you will be better prepared to cope with your feelings and to help others face theirs. Family members should be reassured that sorrow and grief are normal and natural responses to death.

 

They may not understand Sometimes well-meaning family and friends may not realize how important your horse was to you or the intensity of your grief. Comments they make may seem cruel and uncaring. Be honest with yourself and others about how you feel. If despair mounts, talk to someone who will listen to your feelings about the loss of your horse. Talk about your sorrow, but also the fun times you and the horse spent together, the activities you enjoyed, and the memories that are meaningful.

 

The hurt is so deep If you or a family member have great difficulty in accepting your horse’s death and cannot resolve feelings of grief and sorrow, you may want to discuss these feelings with a person who is trained to understand the grieving process. Your veterinarian certainly understands the relationship you have lost and may be able to suggest support groups and helplines, grief counselors, clergymen, social workers, physicians, or psychologists who can help. 


Your veterinarian understands the relationship you have lost

Perhaps the kindest thing you can do for a horse that is extremely ill, severely injured, lame, or dangerous is to have your veterinarian induce its death quickly and humanely through euthanasia. Your decision to have your horse euthanatized is a serious one, and is seldom easy to make.


What should I do?
Your relationship with your horse is special and may be different with each horse you have. When you acquired your horse, you assumed responsibility for its health
and welfare. Owners are sometimes faced with making life-or-death decisions for their animals. Such a decision may become necessary for the welfare of your horse
and your family. Although a personal decision, it need not be a solitary one. Your veterinarian and your family and close friends
can help you make the right decision. Consider not only what is best for your horse, but also what is best for you and your family. Quality of life is important for
horses and people alike.


How will I know when?
If your horse can no longer experience the things it once enjoyed, cannot respond to you in its usual ways, appears to be experiencing
more pain than pleasure, is terminally ill or critically injured, or if the financial or emotional cost of treatment is beyond your means, you may need to consider
euthanasia. Your veterinarian is best qualified to examine and evaluate your horse’s condition and to discuss with you potential disabilities and long-term problems.
Because your veterinarian cannot make the euthanasia decision for you, you need to understand your horse’s condition. If you do not understand the diagnosis or the
implications for your horse’s future, ask to have them explained again. Rarely will the situation require an immediate decision and usually you will have some time
to review the facts before making one. Once the decision for euthanasia has been made, you may wish to discuss the final disposition
of your horse’s body with your veterinarian and your family. Your veterinarian can provide information about burial, removal, cremation, and other alternatives.


What if the horse is healthy?
If your horse has become dangerous, unmanageable, unserviceable, or difficult to maintain, euthanasia may be necessary. Some undesirable and abnormal behavior
can be modified, so it is important to discuss these situations with your veterinarian. Economic, emotional, and space limitations may also force an owner to consider
euthanasia for a horse if a suitable home cannot be found. Discussing all possible alternatives with friends, family, and your veterinarian will help you feel more comfortable with your decision.


How do I tell my family?
Family members may be aware of the horse’s problems. You should review the information you have received from your veterinarian with them. Long-term medical care can be a burden that you and your family may be unable to bear emotionally or financially, and this should be discussed openly and honestly. Encourage family members to express their thoughts and feelings. Even if you have reached a decision, it is important that family members, especially
children, have their thoughts and feelings considered. Children have special relationships with animals. Excluding or protecting children from this decision making process because they are thought to be too young to understand may only complicate and prolong their grief process. Children respect straightforward, truthful, and simple answers. If they are prepared adequately, children usually are able to accept an animal’s death.


Your veterinarian and your family and close friends can help you make the right decision.

 

Should I get another horse?
The death of a horse can upset you emotionally, especially when euthanasia is involved. Some people may feel they would never want to own another horse. For others, a new horse may help them recover from the loss more quickly. Just as grief is a personal experience, the decision of when, if ever, to bring a new horse into your life is a personal one. If a family member is having difficulty accepting the horse’s death, getting a new horse before that person has resolved his or her grief may imply that the life of the deceased animal was unworthy of the grief that is still being felt. Family members should agree on the appropriate time to acquire a new horse. Although you can never replace the horse you lost, you can obtain another to share your life.


Remembering your horse Death is part of the lifecycle.

 

It cannot be avoided, but understanding and compassion can help you, your family, and your friends manage the grief associated with it. Try to recall and treasure the good times you spent with your horse. You may also wish to establish a memorial of some type or contribute to a charity in honor of your horse. 


How can I say goodbye?
Saying goodbye is an important step in managing the natural and healthy feelings of grief, sorrow, and loss. Your horse is an important part of your life, and it is natural to feel you are losing a friend or companion, because you are.  Once the euthanasia decision has been made, you and other family members may want to say goodbye to your horse. Spending some special time with your horse may be appropriate. Family members may want to be alone with the horse. Once all the necessary information is available and the decision has been made, it is best not
to wait too long before having your horse euthanatized. Farewells are always difficult.


Will it be painless?
When the horse is euthanatized, death will be quick and painless. If the horse is standing when the death-inducing drug is given, the horse will become unconscious and unable to sense fear or pain while still standing. After the horse has fallen to the ground, unconscious, death will ensue.


How can I face the loss?
After your horse has died, it is natural and normal to feel grief and sorrow. For some people, spending some time with the horse after euthanasia is helpful. The grieving process includes accepting the reality of your loss, accepting that the loss and accompanying feelings are painful, and adjusting to your new life that no longer includes your horse. By understanding the grieving process, you will be better prepared to manage your grief and to help others in the family who share this loss.  Even if you have reached a decision, it is important that family members, especially children, have their thoughts and feelings considered.  By understanding the grieving process, you will be better prepared to manage your grief and to help others in the family who share this loss.

Learn to Recognize Your Horse’s Dental Problems

Horses with dental problems may show obvious signs, such as pain or irritation, or they may show no noticeable signs at all. This is because some horses simply adapt to their discomfort. For this reason, regular dental examinations, at least annually, are essential to your horse’s health.

It is important to catch dental problems early. If a horse starts behaving abnormally, dental problems should be considered as a potential cause. Waiting too long may increase the difficulty of remedying certain conditions or may even make remedy impossible. According to the American Association of Equine Practitioners (AAEP), the following indicators of dental problems will help you know when to seek veterinary attention for your horse:

1. Loss of feed from mouth while eating, difficulty with chewing, or excessive salivation.
2. Loss of body condition.
3. Large or undigested feed particles (long stems or whole grain) in manure.
4. Head tilting or tossing, bit chewing, tongue lolling, fighting the bit or resisting bridling.
5. Poor performance, such as lugging on the bridle, failing to turn or stop, even bucking.
6. Foul odor from mouth or nostrils, or traces of blood from the mouth.
7. Nasal discharge or swelling of the face, jaw or mouth tissues.

Oral exams should be an essential part of an annual physical examination by a veterinarian. Every dental exam provides the opportunity to perform routine preventative dental maintenance. Mature horses should get a thorough dental exam at least once a year, and horses 2 – 5 years old should be examined twice yearly.

For more information about proper dental care, ask your equine veterinarian for “Dental Care: The Importance of Maintaining the Health of Your Horse’s Mouth,” a brochure provided by the AAEP in conjunction with Educational Partner Bayer Healthcare – Animal Health Division. Additional information is available on the AAEP’s Web site at www.aaep.org/horseowner.

The American Association of Equine Practitioners, headquartered in Lexington, Ky., was founded in 1954 as a non-profit organization dedicated to the health and welfare of the horse. Currently, the AAEP reaches more than 5 million horse owners through its over 9,000 members worldwide and is actively involved in ethics issues, practice management, research and continuing education in the equine veterinary profession and horse industry.

Grooming Tips 


Invest in quality brushes and keep them clean. You can't do a thorough job grooming your horse with dirty or dusty brushes. Also, keeping them clean will help them last longer.
I also like to have a set I only use on show day on a show clean horse.

Curry your horse every day. The more you curry, the more you bring the oils in the skin to the surface. When it comes to currying, there is no substitute for good old-fashioned elbow grease. In winter use shedding blades that aid in removing hair as your horse sheds. In the summer use round rubber curry brushes that come in a variety of sizes and styles. 

Brush the hair in the direction the hair grows.

Don't neglect your horse's hooves. They should be picked out daily, not just when you are getting ready to ride.
Treat your horse's feet to a lanolin-based hoof conditioner at least once a week to keep his hooves conditioned.

When brushing the mane and tail, start at the ends and work your way up, working in small sections. If you want your horse's mane and tail to grow out, don't comb it every day. Instead, just pick out any tangles, shavings or twigs. Working in Corona will help encourage growth but is messy and should be washed out every 4 or 5 days with a gentle shampoo.
To stimulate growth, brush the dock of your horse's tail daily with a dandy brush. This will loosen and remove the dirt and dander that makes your horse itchy. To increase blood flow which stimulates growth brush the dock and upper part of the tail bone.

Dandy Brush                  Rubber Curry              Scotch Comb
  
Bathing
I like to start by wetting the legs from the bottom up, then neck and shoulders and up the barrel to the back and then hips. Then I shampoo and apply conditioner to the mane and tail and let it soak as I am working on the rest of the horse, doing one section at a time, from the front of the horse to the back, and from the top of the horse to the bottom. When bathing your horse, soft sponges hold more water than soft brushes. Loosen stubborn stains or dirt with the soft brush and flush with the sponge. When hosing your horse, direct the stream of water from the front to the back so that you don't accidentally squirt him in the face. Use a sponge on face and just a damp rag to wipe out ears. Never spray water at horses’ ears.
Don't forget to wash underneath his tail and between his back legs.

Clipping
When clipping use clean, sharp clipper blades. Making sure your clippers are in good working order to ensure the best results.
Use baby powder, corn starch or French chalk on white socks to brighten them.

Keep cling-free dryer sheets on hand. You can run them through your horse's mane or tail to reduce static electricity.
If you pull your horse's mane, use a pulling comb or Scotch Comb to make the job easier. Pulling your horse's mane after you ride makes the hair easier to remove as the pores will be open.
Use Listerine to desensitize areas to be pulled. Rub a little onto the base of the mane before you begin pulling the hair and when you are finished to ease the itch.
Use a bit of baby powder on the inside front of your horse's blanket to help cut down on rubbing. It also stops squeaky saddles.


 

Safety



Catching your horse
You always want the head facing you not hind feet!
If there are other loose horses in the pasture or pen, make sure they all know you are there and stay alert!! You never know when a loose horse could lunge at other horses and cause one to run over you.  Pay very close attention to un-broke horses as they will have less respect for you than the lead horse in the herd.

Make sure you put the tail of the lead rope around your horses neck and cross it so you have control should your horse try to walk off while you are haltering him.

Leading
When leading your horse stay at his throatlatch to the side...NEVER walk directly in front of your horse.
Never walk up behind your horse without speaking to him before you touch him and letting him know you are there. Never let your horse in your space.

Use your lead rope with short quick pulls to keep his attention on you. You will never win a tug of war with your horse...Be smart out think him. Don’t always have pressure on the lead rope when leading your horse. It is his natural instinct to pull away from pressure. If your horse is already pulling away from you because he is scared you pulling will only make his panic worse, if he is pulling because he is disrespectful, you will not be able to hold him anyway and short quick jerks on the lead will get better response. Just like when your riding, always pulling on his head will become something he will dread or ignore.
Make your cues mean something.  On the ground and on his back.

If you don’t have his respect on the ground you will likely have problems from his back. Make sure you are being the leader of your team.

tying 
Tie to something solid that your horse can not break or drag. Never tie to a gate.

Never tie with your reins.

Make sure your Halter and lead rope are in good condition so if your horse does pull back he can not break away.

Always use a quick release knot.

Tie at about throatlatch high, with no more slack in the rope than 2 feet.

You NEVER tie you horse so he can pick grass or eat hay from the ground...No matter how sad or hungry he looks...It can have disastrous results.


Never get on a tied horse.

 

Mounting

When you get on always have control of your reins, and tip his head slightly around toward you.

Make sure your horses feet are squarely placed under him so he can hold your weight as you mount.
When you get on, get on don’t take for ever, and when you get off do the same get off...Make sure your foot is pulled out of the stirrup so you don’t get hung up...Remember the wider the tread of your stirrup the more likely the chance of your foot being caught in the stirrup.


When mounting check the area to make sure you will not hit your head on anything when you are mounted.

When you get on your horse always make him wait to move until you are ready.


Other Safety Reminders

Always say something to your horse when you approach him so he knows your there.

Make sure your bridle is adjusted correctly and in good condition.
Make sure your saddle is tight enough and your girth and latigo is clean and in good condition.


Never ride your horse up on the rear of another horse. Keep your distance, even if you are standing around other horses.

Never run your horse though a crowd of other riders, you could cause problems for your self or other riders.
Be courteous.

ALWAYS BE THE LEADER!!!

Top 5 Signs of Potomac Horse Fever
Quick recognition of signs, vaccination helps prevent fatality


DULUTH, Ga. — The name is deceiving, but Potomac horse fever (PHF) is not just a concern for horses near the Potomac River. Cases have been found across most of the United States.1 Knowing the key signs of PHF and watching carefully for them can help alert owners to protect other horses at risk for infection.

“Every veterinarian and horse owner worries about laminitis and colic. These could be classic signs of PHF in the right context,” says Frank Hurtig, DVM, MBA, Director, Veterinary Services. “Recognizing the signs of disease offers a cue for quick PHF testing, and examination for other disease concerns. Timely vaccination of horses in the area can help prevent against additional cases of PHF.”

Some of the most commonly occurring signs of PHF are:1

Fever
Colic
Diarrhea
Above signs, followed by laminitis
Abortion in pregnant mares
Up to 30% of PHF-infected horses die,1 and laminitis may continue even after other signs have stopped. If a PHF case is located, all the horses in the area may be at risk for infection, Dr. Hurtig warns.

PHF commonly occurs near bodies of water during mid- to late-summer.1 However, it has been found in nontraditional areas as remote as northern Wyoming.2 PHF has a complex life cycle in which Neorickettsia risticii infect freshwater snails containing flukes. Then, N. risticii is transferred to aquatic insects such as caddisflies and mayflies. Horses become infected after eating grass, feed or water containing these insects.1

Draining water and other management practices can help reduce the risk of PHF transmission.1 To help prevent against the most severe complications of the disease, Dr. Hurtig recommends vaccination.

“Vaccination seems like a simple investment when there is a possibility of colic, laminitis or even death,” Dr. Hurtig says. “In recent years, PHF cases appeared in several nontraditional states. That makes it a real concern for horses in all areas of the country.”

In an efficacy trial, POTOMAVAC™ from Merial protected 86% of horses from clinical disease.3 POTOMAVAC is proven safe for horses as young as 3 months and is demonstrated safe for pregnant mares. Plus, it is available as Equine POTOMAVAC + IMRAB® to help protect against both PHF and rabies.

Pasture and Poisonous Weeds


     The most common problem with pasture is there is not enough of it.  We over graze pasture very frequently and that can lead to weed problems. Most plants contain some sort of toxic ingredient, and anything can cause colic when over consumed. It is hard to know what causes the poisoning if you don’t know what the horse ate. There are very few ways to test for plant toxins in animal fluids. The best way to prevent problems is to keep favorable grass for your horse to eat. An adequate stand of Blue Grass, Orchard Grass, or Brome is ideal horse pasture. Keep it fertilized and don’t over graze and weeds should not become a problem.

 

     Fescue is very common grass and is fine for horses. It can cause very serious problems with pregnant mares. Pregnant mares should not be allowed to eat Fescue Grass or hay with Fescue in it in the last 30 to 60 days of pregnancy, as it can cause the placenta to thicken so much that the foal can not brake the sack and will suffocate or it can cause a mare to not have milk.


     The most common deadly plant is the Yew shrub. The lovely bushes we use to landscape around our houses and trim at least yearly. Disposing of the clippings can be deadly for your livestock. The very thing that makes it so desirable for ornamental use, its insect resistance, is what makes it poisonous to horses, cattle, hogs and most livestock. Never give a horse access to the shrub or clippings. Just a few sprigs can kill a horse.


     Oak, Black Locust, Red Maple, Black Walnut, and Wild Cherry trees are all toxic. If your horse finds these trees leaves attractive, they should be fenced off. The agent that makes the leaves change colors is what causes the leaves to become toxic when consumed.  Buckwheat, St Johnswart, and Alsike clover can cause extreme sensitivity to sunlight.  Skin with out pigment, such as a blaze or white nose, may become swollen and eventually slough off or become scabby. In wet weather Clover can get black patch disease, which is caused by a mold that also produces a potent agent that causes sudden slobbering in horses. This will go away when the horse is removed from the infected pasture or when the weather dries up and the cover is not so plentiful, however serious problems can occur with prolonged exposure, such as dew poisoning which effects the liver and can cause weight loss and Photosensitivity.

 

Yew Shrub
Form: Low straggling shrub often having widespread horizontal limbs, to 5 feet tall, if not trimmed.
Leaves: Evergreen, needles are green above and below, about 1 inch long, sharp pointed and stalked with a base that continues down the side of the smooth twig.
Fruit: The berrylike fruit is an aril which is a juicy, scarlet red fleshy cuplike dish surrounding a single seed which is poisonous.

 

White Snakeroot


  • Family: Aster (Asteraceae) 
  • Habitat: woods, thickets
    •   Height: 1-3 feet
    •   Flower size: flowerheads around 1/6 inch across
    •   Flower color: white
    •   Flowering time: July to October
    •   Origin: native

Wild Buckwheat


Weed Description: An annual twining or trailing vine that may reach as much as 3 1/2 feet in length. Wild buckwheat is found throughout the United States
Leaves: Leaves are alternate, triangular to heart-shaped with a pointed tip. Basal lobes point inward toward the petiole. Leaves have a continuous, untoothed
margin.


St Johnswort

Grazing: St. Johnswort presents difficult problems for grazing, given its chemical constituents. It depresses the central nervous system and increases the animals' sensitivity to temperature change and handling. St. Johnswort also affects the liver, causing temporary sensitivity to sunlight. Livestock usually avoid it unless food is scarce. Excess consumption leads to blistering and itching on light-haired or unpigmented skin areas including the mouth, nose and ears. Dark skin is not affected. The animals may lose weight, become difficult to manage, and they may die of dehydration or starvation if there is swelling or soreness in the mouth. Cattle need to ingest only 1% of their body weight to be affected, whereas sheep can consume up to 4% of their weight. The wool and meat of affected animals is often of poor quality. Horses, rabbits and pigs are also affected by the herb, but I have not found any information reporting whether or not goats are affected. The dried plant as found in hay is much less potent than fresh, but may still cause problems.



Description and Variation: Saint Johnswort is an erect, opposite-leaved perennial herb, ranging from two to four feet tall arising from a taproot. The plant can have single or multiple stems. The reddish stems are smooth, somewhat two-edged, woody at the base, and branching out toward the top of the plant. The narrow, lance shaped leaves are about one inch long, stalkless with pointed tips. Each leaf is spotted with tiny translucent dots. Each flower has five yellow petals and many yellow stamens. The black dots often visible along the petal margins are glands containing hypericin. This red pigment is also visible in glands on leaf margins giving the leaf a perforated look. The inflorescence is a flat topped cluster of many flowers found at branch ends. The extended flowering period is from May to late September. St. Johnswort spreads both by underground and above-ground creeping stems, and by seed. The Hypericaceae family contains 10 genera and 400 species, worldwide. An estimated 350-370 species are in the genus Hypericum.

 

Black Walnut 

The 1- to 2-foot long leaves are made up of 12 to 24 leaflets growing from the rachis. The leaves are compound with an even number of sharply pointed leaflets.
Fruit is a green-black husk covering a 1- to 1 1/2-inch nut inside. Careful-they smell and will stain your hands.
Walnuts usually are the first to drop leaves in fall and the last to sprout new leaves in spring.

Red Oak

Leaves are soft, fluttery and bright green on the top side and silvery gray-green underneath.
Fruit is a pair of winged seeds, also called helicopters because of the way they spiral when they fall. Bark on older trees breaks into long, thin plates.
Oak and hickory trees are the most plentiful kinds of trees found in Missouri. They make up about three-fourths of the trees growing in our forests.
There are many different kinds of oak trees in Missouri-21 different species of oak trees and at least 16 hybrids. That's a lot of oak trees.
Oaks produce acorns that look like little heads wearing caps. They vary in size and shape among species. Many animals rely on acorns for food, especially deer and squirrels.  Some horses will eat tham and can cause impaction problems.

 

Wild Cherry Tree


The Wild Cherry Tree is a medium sized tree. The trees can grow to be almost twenty-five yards tall. Trunk diameter is close to about one yard. This tree has a rounded with pointed and rough twigs. If you don’t have a field guide to identify this tree, look for thick leaves that curve inward. This Wild Cherry is similar to the choke cherry which is smaller than the wild, black, cherry.
Growth Form
Tall and rounded tree. Pointed and rough twigs on tree. Adult tree trunk can grow to three feet in diameter. Adult trees grow to seventy-five feet tall. Look for thick leaves that curve inward toward the tree.
Leaf
Leaves on the wild cherry have alternate placement on the branches. They appear oval shaped and up to about five or six inches long. Teeth are on the outside edges and smooth on the other side of the leaf. They are green and shiny on the upper surface, and hairs on the midrib and spines. The leafstalk gets up to a little less than one inch long. There are a couple of red openings near the tip.
Bark
The bark is slick and thin. The color is reddish brown then turns into black.
The bark treats chronic coughs.
