Race and performance horses as well as foals undergoing stress are susceptible for developing stomach ulcers, also known as EGUS. In fact, up to 93% of racehorses get stomach ulcers in their lifetime, and almost 60% of performance horses have ulcers. Up to 57% of foals have stomach ulcers, particularly during the first several months of life.
A stomach ulcer is a wound on the lining of the stomach. Unlike in humans, where ulcers are thought to be primarily caused by the bacteria H. Pilori, the horse develops ulcers due to stress, feed intake, and management practices. Horses evolved on the plains, continuously grazing on lower quality forages. To accommodate this eating pattern the horse continuously produces acid into the stomach. This acid is beneficial to digestion when food is present in the stomach, but harmful to the stomach lining when the stomach is empty, causing stomach ulcers. Saliva acts as an acidneutralizer. Increased salivation occurs when a horse chews hay and grass, which, when swallowed with the bolus of forage helps to neutralize the acid in the stomach. Also, roughage present in the stomach absorbs quite a bit of the acid, keeping the level within the stomach normal.
Race, performance, and show horses are generally housed indoors and fed a higher concentrate (grain) diet. Grain or pelleted feed increases the level of a hormone known as gastrin. Gastrin is released by the stomach and acts as a stimulant for acid production. Depending upon feeding schedules, a horse may consume his grain, then have to wait to be feed his hay (roughage), all the while producing excess stomach acid.
Another reason for EGUS is exercise intensity. Studies have documented that the occurrence of ulcers increases as the level and duration of exercise increases. It is not clearly understood why this happens, but possibilities include that while the horse is exercising he is not eating and the stomach remains empty for longer periods allowing acid to injure the stomach lining.
Diagnosing EGUS can be difficult, especially since the horse can't tell us where he is hurting. Gastroscopy (examining the inside of the stomach with a camera) can confirm stomach ulcers. If your horse is in training, the chances are fairly good that he has stomach ulcers even if you do not recognize any symptoms. Often only after treatment for ulcers does an owner realize how "off" their horse was and how improved its attitude, condition, and performance is. The chart (on the front page) outlines typical symptoms of ulcers in the adult horse and in foals.
If stomach ulcers are suspected or confirmed, treatment with omeprazole (GastroGard®)is indicated. Omeprazole works by reducing the production of stomach acid, thus allowing the stomach to heal, Additionally, the horse should be fed hay more frequently thoughout the day, or, if possible, turned out on pasture to graze. The owner may also wish to reduce the horse's work load for a few days until he appears to be feeling better.
Owners of horses with the propensity to develop EGUS also have the option of using UlcerGard® to aid in the prevention of ulcers.
As with all health issues, the veterinarians at the Elkhorn Veterinary Clinic are eager to assist you in making the best choices for your horse.

Composting Manure - Good for Your Horse and the Environment
Each day, the average horse produces 50 pounds of manure not including the bedding that is removed with the manure when stalls are cleaned. How to dispose of all that waste can cause headaches for horse owners. Owners may contract with a waste removal company, which can be expensive. Manure left in piles attracts flies, creates an unpleasant odor for neighbors, and may cause serious surface water contamination. Spreading fresh manure on pastures broadcasts parasite eggs, leading to parasite reinfestation when horses graze.
Composting manure is an excellent management tool for all sizes of horse properties, from the backyard or small farm owner to the large stable. Composting speeds up the natural decomposition of the manure while turning it into a dark, crumbly, earthy-smelling product similar to potting soil. Other advantages are:
- Composting generates heat which kills parasite eggs, fly larvae, pathogens and weed seeds.
- Composting reduces flies by eliminating their breeding ground.
- Composting reduces odors.
- Composting reduces the volume of waste material by 50%.
- Composting reduces the incidence of manure contaminated runoff reaching surface or ground water.
- Composting transforms a potential liability into a valuable resource.
Composting bins can be fairly easy to assemble. They are three-sided bins, using common sides. The size and number of the bins are determined by the number of horses in the herd and the type and amount of bedding used. One or two horse herds can generally get by with two bins. Larger herds may need three bins.
The location for the bins should be on high, level ground convenient to the stall and paddock areas. Bins should either be covered with a roof, or the manure covered by using a tarp to assist in the control of moisture.
To speed decomposition, piles should turned to allow oxygen to get to the bacteria and organisms which break down the manure. Additionally, the compost pile should be kept as damp as a rung-out sponge. Depending on how often the compost pile is worked, composting should take a couple of months in the summer and three to five months in the winter. The compost is ready when the material is reduced by about 50% and the material appears evenly textured and crumbly like soil.

Introducing Your Horse to Pasture
It's spring, our pastures our green and lush, the weather is warm, and the days are lengthening. It's tempting to throw open the barn door and let the horses enjoy themselves grazing on the new grass after a winter of hay. However, the abrupt change in diet can be detrimental to your horse.
To avoid health concerns such as colic,
ounder or laminitis, it is best to introduce your horse gradually to pasture. Horses may be turned out for a half hour to graze, with an increase of ten minutes daily until the horse can be left out for several hours.
Ponies and horses with Cushing's, Equine Metabolic Syndrome, or a history of laminitis should be started more slowly as they can
be especially prone to grass founder.
If you are concerned that your horse may gorge himself on grass, feed him his hay before turning him out to graze. You may also purchase a grazing muzzle for your horse to limit his grass intake.
Dr. Leiblse Board Certified in Equine Practice
Preventive Medicine the Key to Cost-Effective Care

The Elkhorn Veterinary Clinic is proud to announce
that Scott Leiblse, DVM, has been certified as a Diplomate by the American Board of Veterinary Practitioners (ABVP), specializing in equine practice. Dr. Leibsle is the only veterinarian in Wisconsin
that holds this board certification.
Dr. Leibsle mastered a rigorous and demanding application process and certification examination in order to obtain Diplomate status. To qualify to sit for the extensive, two-day examination, a veterinarian must complete either a residency program or six years of clinical veterinary practice. In addition, two case reports, references, descriptions of practice procedures, and professional education
records must be submitted and pass review.
Dr. Leibsle is a graduate of the University of Wisconsin-Madison School of Veterinary Medicine. He has a special interest in dentistry, lameness, and soft-tissue surgery.
It's no secret that our economy has been hit hard the last few years. Everyone seems to be tightening their belts with horse owners being no exception. Owners may have a tendency to put off preventive care in
order to save money, but this strategy usually backfires.
Vaccinations are the most important element in preventing infectious
and deadly disease. The price of the immunization is far less than the cost
of treating the disease. For instance, it costs approximately 20 times more
to treat a case of influenza in the horse than the vaccination would cost.
The cost to treat a horse with West Nile Virus can be in the thousands of
dollars and the prognosis is poor. In some cases, owners are forced to
make the difficult decision to euthanize the horse because treatment is
beyond their economic means.
Annual dental care is essential to maintaining the overall health of the
horse. Sharp points should be filed (floated) so the horse can better grind
his feed, allowing higher utilization of the grain and hay, therefore reducing
feed costs. Annual oral exams are even more important with older horses
as they often have problems such as loose teeth, infected roots, or uneven
wear which makes it difficult for them to eat and may predispose them to
other health problems.
Deworming recommendations have changed due to the increased
parasite resistance to current dewormers. Fecal egg counts and fecal egg
count reduction tests are essential to determine the type of dewormer to
use and the number of times a year your horse should be dewormed.
