Wellness At Home

Many diseases in horses can be serious and even life threatening. They can be expensive to treat and may require significant convalescent periods, during which the horse cannot be shown, transported, bred or ridden. Vaccination is a relatively inexpensive and effective way of helping protect equine health. Thankfully, effective vaccines are available for many of the infectious diseases affecting horses. While they may not prevent all infectious disease, they can help minimize clinical signs and the severity of infection. On many farms, indicated vaccines are typically administered seasonally, in the spring and the fall. Vaccines can be administered as an individual dose for particular diseases or in combination doses for multiple diseases, this allows your veterinarian to customize a vaccination program for your horse. Core vaccines are those that the American Association of Equine Practitioners (AAEP) considers being essential to maintaining the health and well-being of the average horse; in addition, some are necessary to help safeguard human health. The core vaccines are Tetanus, Eastern and Western Equine Encephalomyelitis, West Nile and Rabies.
Grooming does more than make your horse look good. Brushing, bathing and clipping help keep your horse's skin and hair coat healthy. Ideally, you should groom your horse daily and after exercise. Although daily grooming is time consuming, the effort benefits both you and your horse by strengthening the bond between you and keeping you aware of your horse's overall health. Groom your horse in an area that allows easy access to all parts of your horse. For bathing, choose an area that will not get muddy or slippery. Use a leather halter and/or quick release cross ties while grooming your horse so that if he panics, you are both less likely to be hurt.
One of the first questions you have to answer after getting your first horse is : "Does he need shoes?" The answer depends on the quality of your horse's feet and the type of surfaces on which your horse will be kept. Horses working on hard or rough surfaces require shoes for protection, as do horses with bruised or tender feet. Some horses have very thin soles and shoes protect their feet from bruising. Many hoof problems can be avoided by properly evaluating the feet and taking the appropriate precautions. When you evaluate your horse's feet, consider the following. First, examine the hoof wall for cracks. A brittle wall can allow entry of dirt, bacteria, and fungi, which can lead to abscesses (pus-filled swellings), seedy toe and white line disease, all of which cause lameness. A brittle, cracked wall is primarily a genetic problem. If your horse has this problem, shoeing will help because the horseshoe holds the hoof together, reducing chipping. Adding biotin and methionine to a horse's diet also helps to produce a better, thicker hoof wall. These additives are inexpensive and easy to find. The second consideration is the shape of the hoof. Is there too much toe? Is the heel too far under the hoof, indicating under-run heel? Is the sole of the hoof too close to the ground, indicating flat footedness? Shape abnormalities predispose horses to lameness. Corrective shoeing can help minimize these problems.n
It has become commonplace to trailer horses everywhere: a short trip to the park for a trail ride, a lesson across town, or an appointment at the veterinary hospital. Traveling three states away for a horse show or field trip or traveling south for the winter used to be a big deal, but not anymore. Because horses are traveling more, it's easy to forget that trailering can be very stressful for them. It is stressful for horses to enter a small, enclosed trailer and then speed down the highway at 65 mph. Horses prefer open spaces, where their instinctive flight response can be lifesaving. Everything you can do to reduce this stress will be a benefit to your horse. Horse owners should take precautions to be sure the trailer is safe and comfortable, so their horses do not harm themselves or others. Also, after long distance trailering, horses need several days to recover and regain full immune function.
Thin Horse
Many horses maintain a good body condition if offered a sufficient quality and quantity of pasture and free-choice hay (as needed). Younger horses or horses in work require additional food, such as high energy feeds or concentrates to meet their nutritional needs; older horses often require a senior or complete feed because they lack adequate teeth. If your horse suddenly loses weight, it is important to assess your horse's health and any changes in how your horse is managed. Horses can suddenly lose weight due to underlying health problems. The following can help to determine the cause of weight loss and to minimize potential problems:
  • If your horse suddenly loses weight and/or your horse's body condition worsens, contact your veterinarian. Offer adequate pasture and/or free-choice hay and feeds.
  • Minimize your horse's exposure to sudden environmental changes and slowly acclimate your horse to other changes, such as changes in feed and companions.
  • If high energy feeds such as grain or concentrates are needed to maintain your horse's body condition, you can avoid problems such as gastric ulcers by feeding small, frequent meals rather than one or two large meals of grain daily.
Avoiding Injuries
While horses have been domesticated by people for a long time, it is important to remember that they are still animals with a very strong instinct for "fight or flight" when danger is present. When presented with a threat, many horses will try to run away; however, some horses will choose to fight against the danger and may kick, rear, or bite in response to the threat. It is important to follow certain safety guidelines when working with horses to avoid injury for you and your horse. Remember, an adult horse often weighs 1,000 pounds or more and can easily injure a person with minimal effort. Common steps to avoid injury include using proper restraint. This can vary depending on the horse, but at minimum a strong halter in good condition and lead rope with a chain should be used. Separating certain horses such as stallions or mares with foals from other horses on the property and using separate barns or pastures/enclosures is important. This will avoid exposing stallions to mares in heat and potential problems associated with their interaction. Mares with foals are often very protective and may injure a person trying to interact with their foals. In addition, only experienced people should handle stallions or mares with foals. It is also important to approach horses when they are facing you and not approach them from the rear. They are not able to see the area near their tails and will often kick when they feel threatened by someone approaching their hind end. It is also imperative to wear protective clothing around horses, such as sturdy shoes or boots, and avoid loose fitting clothing that may become caught on their halters or lead ropes.

Specific Conditions

The word colic describes abdominal pain, which can be caused by many different problems. It can occur suddenly or gradually over a period of days. Horses often develop colic because their digestive systems are very long (more than 100 feet) and complex. Certain parts of their digestive system are prone to develop twists and impactions (blockages) of food material. Also, horses digestive systems are designed for foraging, eating small amounts of food throughout the day while on the move. However, domestic horses are often fed large amounts of highly concentrated diets (e.g. grain) two or three times a day and kept in small areas without enough pasture turnout, grazing and exercise. Stress from activities such as racing or showing may also contribute to colic. Colic can have many signs, but the most common can include: Decreased eating and/or drinking. Reduced quantity of manure or decreased frequency of defecation. Change in consistency of feces (e.g. small, hard manure balls vs. large, soft manure piles. Disturbed bedding, showing that your horse has been pawing or getting up and down. Kicking at abdomen. Pawing. Looking back at the abdomen. Lying down and getting up repeatedly. Rolling or thrashing. Sweating. Increased respiration/breathing rate. Increased heart rate. Fever. Lack of gut sounds (check with stethoscope). The most important step in treating colic is to contact your veterinarian immediately. Do not attempt to diagnose and treat colic on your own. Most colic cases can be treated at the farm by your veterinarian with the use of pain-relieving medications, muscle relaxers, laxatives and fluids. However, some cases require more sophisticated diagnostic tests and/or surgery and will need to be transported to a clinic. In general, the more intense the signs are of pain, the more serious the episode of colic.
Infection with Streptococcus equi equi, also commonly known as strangles, is a very contagious infection that can spread quickly among horses. It can affect one or two horses on a farm, or many horses affected in large outbreaks. While any horse can develop strangles, young horses are more often affected. This infection is usually spread through contact with an infected horse through nasal discharge (such as nose-to-nose contact with a horse that has a runny nose) or sharing equipment (such as buckets and automatic waterers) or through contact with people handling an infected horse. The bacterium Streptococcus equi equi infects horses' lymph nodes, especially under the jaw and around the throat. Horses that routinely have contact with unfamiliar horses (such as at shows or other events) or that are boarded with horses that travel are more likely to develop this contagious infection. Clinical signs usually start between 3 and 14 days after exposure to a contagious horse. An affected horse may have a fever, depression, loss of appetite, thick, yellow/whitish nasal discharge and visibly enlarged and/or draining lymph nodes have difficulty swallowing due to enlarged lymph nodes. Affected horses have difficulty swallowing due to enlarged lymph nodes. Horses with severely swollen lymph nodes have difficulty breathing; therefore, the disease is known as strangles. Clinical signs can range from mild (fever and mild nasal discharge) to severe (labored breathing and death due to obstruction of the airway by enlarged lymph nodes).
Tetanus is caused by the bacterium Clostridium tetani. Spores from this bacterium can be found almost everywhere in the environment. Tetanus is a serious, frequently fatal disease. Once the bacteria infects a wound, they release neurotoxins that can cause muscle spasms and paralysis leading to death. The disease rarely occurs in properly vaccinated animals. Tetanus can result from any kind of wound, even a small one, but it is most frequently associated with puncture or wire wounds in the feet or muscles, surgical wounds and exposed tissue, such as the umbilicus of foals or the reproductive tracts of mares that have recently foaled. Diagnosis is generally achieved by a thorough physical examination of the affected horse and blood tests. Treatment is a combination of supportive therapy, tetanus anti-toxin and medications such as antibiotics. Severely affected horses often do not survive due to complications.
Rabies is a serious disease that is 100% fatal. However, it is almost completely preventable through vaccination. While the incidence of rabies in horses is low, it is a serious public health threat for anyone who is involved in handling horses. The rabies virus attacks the central nervous system (brain, nerves and spinal cord) of mammals and is transmitted through infected saliva, either through a direct bite wound or by contact with any open wound or mucous membrane. Clinical signs vary widely and can take anywhere from weeks to months to develop after exposure. Signs frequently include behavioral changes, un-coordination, muscle tremors, seizure, paralysis and coma. Rabid horses may present with clinical signs of colic. However, the signs are non-specific and rabies can be extremely hard to diagnose. There is no treatment. Once clinical signs appear, rabies is 100% fatal as well as contagious to people handling the horse or the horse's body fluids.
West Nile Virus
Like EEE/WEE, West Nile virus is transmitted by mosquitoes. The disease is associated with a significant death rate of about 35%. Approximately 40% of horses that recover still show residual effects more than 6 months after recovery. West Nile is currently the leading cause of encephalitis (inflammation of the brain) in horses in the United States. West Nile virus can cause potentially life-threatening encephalitis. It attacks the spinal cord and brain and can cause un-coordination, muscle twitching, depression, paralysis and erratic behavior such as hypersensitivity to the head and neck being touched. Horses that are severely affected may become recumbent (unable to stand) and eventually die. Diagnosis is generally achieved by a thorough physical examination and testing of blood and cerebrospinal fluid, if needed. Treatment is primarily supportive (e.g. intravenous fluids, anti-inflammatory medication, nursing care).
Potomac Horse Fever
Potomac Horse Fever (PHF), also known as equine monocytic ehrlichiosis, is caused by the bacterium Neorickettsia risticii. Despite its name, PHF is found throughout most regions of the United States and Canada. The disease is seasonal, generally appearing in the spring, summer and fall and is associated with pastures located near waterways. Signs of infection vary, but may include fever, mild to severe diarrhea, laminitis and colic. As a result, the disease can result in fatal complications and has a death rate of 5% to 30%.
Eastern and Western Equine Encephalomyelitis
These two serious diseases are transmitted by mosquitoes. The risk of infection exists almost anywhere in the United States where mosquitoes can be found and during all parts of the year when they are present. EEE is more prevalent in the eastern United States; WEE is more prevalent in the West and Midwest. Although infection is relatively rare, the disease can be catastrophic. Approximately 50% of horses infected with WEE die. The fatality rate among horses with EEE approaches 90%. Humans can also get EEE/WEE. These viruses attack the brain and spinal cord and can cause un-coordination, muscle twitching, depression, paralysis and erratic behavior. Horses that are severely affected may die. Diagnosis is generally achieved by a thorough physical examination and testing of blood and cerebrospinal fluid. Treatment is primarily supportive (e.g. intravenous fluids, anti-inflammatory medication, nursing care).
Equine Infectious Anemia
The coggins test is used to detect Equine Infectious Anemia (EIA) - a highly contagious and potentially fatal viral disease of horses. EIA is a reportable disease and is therefore regulated by the United States Department of Agriculture (USDA), but state laws vary. A current, negative coggins test result is often required to transport horses across state lines. Horses that attend equine events are usually required to show a current, negative test result to participate, even within your home state. In the 1970's, veterinarian Leroy Coggins developed the test that bears his name. With no vaccine available, the only way to prevent the spread of this highly contagious disease is to identify infected horses and then separate or isolate them from non-infected horses, so the virus is not transmitted. EIA virus is most often spread through biting insects, primarily horseflies and deerflies. It can also be transmitted through saliva and other bodily secretions, shared syringes and any objects contaminated with infected blood or fluids. Infected pregnant mares can pass the virus to their foals. While the USDA estimates that fewer than eight in 100,000 horses become infected with EIA virus, 50% do not survive despite treatment. EIA comes in 3 forms: acute, chronic and the inapparent carrier. In the acute form, horses experience fever, lethargy and loss of appetite and many die within a few weeks even if they receive aggressive treatment. If they recover, they become chronic carriers and are contagious for life. Chronicallly infected horses become ill, recover and then become sick again and never completely recover. They often lose weight and suffer from anemia and swollen limbs. Horses that are inapparent carriers appear healthy, but can spread the disease to other horses, or eventually become ill themselves.
Equine Protozoal Myelopathy
Equine protozoal myeloencephalitis (EPM) is a disease that causes spinal cord problems and brain inflammation in horses. It is caused by infection with certain microorganisms, one of which is carried by opossums. In the Americas, EPM is caused by a microorganism called Sarcosystis neurona in a horse's feed or water. Horses can be affected at any age. Signs of EPM vary according to the location of the infection in the body. Signs are very rare in horses younger than 12 months. Infection of the spinal cord is common, resulting in weakness, loss of coordination and wasting of the rump muscles (one side of the rump is often smaller than the other). Other signs include sudden sweating, head tilt, facial paralysis, vision problems, behavioral abnormalities and seizures. Some signs may not occur until years after infection. Diagnosis is based on signs, cerebrospinal fluid testing and your horses response to medication. With medication, horses can recover from EPM; however, neurologic damage can be permanent. Treatment can take 28 days to 6 months, depending on the drug, which is applied as an oral paste. Without treatment, EPM is often fatal. A vaccine is available to help prevent EPM and its effectiveness continues to be evaluated by researchers.
Equine Influenza Virus
While equine influenza is a type 2 virus is rarely fatal except in debilitated animals, it is highly contagious and can cause significant illness resulting in extended loss of training and use. Equine influenza is marked by rapid onset of high fever, lethargy (tiredness) and cough. The virus is mainly spread through the air. Treatment is primarily supportive care and rest. Non-steroidal anti-inflammatory drugs (NSAIDS) and antibiotics may be prescribed if the horse's fever persists or if a purulent nasal discharge develops, which may indicate a secondary bacterial infection.
Proud Flesh
When a wound begins to heal, the new tissue is very fragile. If the wound is located near a joint where there is a lot of motion, the fragile new tissue tends to break down and rebuild several times before the wound heals completely. In some cases, an overabundance of new tissue is produced during the rebuilding phase of healing, overrunning the wound and impeding the healing process. This exuberant granulation tissue is called proud flesh, which is common in leg lacerations - one of the most common conditions that veterinarians evaluate in horses. Wounds should be treated as soon as possible because untreated wounds are more likely to become infected or develop proud flesh. The treatment of wounds with proud flesh usually depends on the extent of the overgrowth. If proud flesh is detected early, its progression can be diminished by applying special wound powders, allowing normal healing to continue. More often, however, excessive proud flesh is not detected immediately and must be trimmed by a veterinarian to permit proper healing. With proper care, the wound can then heal with little or no scarring.
Exertional Rhabdomyolysis
External rhabdomyolosis (ER), which is also called tying up, is a disorder of the metabolism of the muscle that results in muscle cramps in horses. In severe cases, an affected horse's urine appears red from the release of myoglobin (an oxygen-transporting protein) by damaged muscle and muscle enzyme levels are greatly increased. Most cases of ER occur in horses that have not been in work for several days and are then exercised strenuously. Typically, an affected horse develops a stiff gait with excessive sweating and rapid breathing during or shortly after exercise. The horse's muscles are hard and painful to the touch. ER can often be prevented by supplementing the feed daily with an electrolyte supplement that includes at 1oz of NaCl and by ensuring that the dietary carbohydrate level is not too high. Affected horses should be kept on a consistent exercise program.
Botulism is caused by the bacterium Clostridium Botulinum. This bacterium can be present in the soil as the spores, especially in certain areas of the United States, such as mid-Atlantic states. The spores can germinate into active bacteria that produces a neurotoxin called botulinum toxin. Horses may be exposed by eating food contaminated with the toxin or the spores themselves (foals) or through wound contamination with soil that contains spores. This infection can occur at any time of year. The disease is not contagious, but outbreaks may occur if a number of horses eat contaminated hay or grain. Signs of infection include difficulty chewing/swallowing and progressive weakness, culminating in recumbency (inability to stand) and death. Diagnosis is made through physical examination and blood and/or fecal tests. Treatment is very expensive and consists of administering antitoxin and supportive care, including intravenous fluids and feeding the horse through a tube a few times per day. Horses that are severely affected are likely to develop respiratory paralysis, leading to death.
