Exploring Aloe Vera for Equine Gastric Ulcers
In the seemingly never-ending battle against equine gastric ulcers, a research team from the University of Adelaide in South Australia reached for an unusual solution: aloe vera. According to those scientists*, aloe vera isn’t just soothing for burnt or irritated skin but also potentially beneficial for protecting the sensitive lining of the stomach.
“The inner leaf gel of the aloe vera plant has been reported to be effective in the prevention and treatment of gastric ulcers in man and in animals in experimental models. Its anti-ulcer properties have been attributed to a variety of possible mechanisms, including anti-oxidant activity, anti-inflammatory properties, cytoprotective and mucus-stimulatory effects, and its ability to regulate gastric acid production,” explained the researchers...Read More...
Water-Soluble Vitamin E for Horses Proven Superior
Vitamin E (alpha-tocopherol) supplementation helps prevent various disorders affecting both the nervous and musculoskeletal systems, including neuroaxonal dystrophy/equine degenerative myeloencephalopathy, equine motor neuron disease, vitamin E deficient myopathy, and nutritional myodegeneration. These conditions can be prevented largely by providing adequate dietary vitamin E to horses, and recent research shows* that a liquid vitamin E supplement may be more beneficial than a powdered formulation.
“The current recommended daily dietary intake of vitamin E for adult horses is 1-2 IU/kg. Many horses obtain adequate vitamin E from pasture. When horses have limited access to pasture, either due to an underlying metabolic condition or during times of drought, and are instead offered hay, vitamin E levels may be depleted. In such cases, vitamin E supplementation could prove beneficial,” explained Kathleen Crandell, Ph.D., a nutritionist for Kentucky Equine Research (KER)...Read More...
Electrolytes Vital for Performance Horses
More than one horse owner has asked herself this simple question, “Why don’t feed manufacturers put electrolytes in feed specifically designed for performance horses?” According to Joe Pagan, Ph.D., founder and owner of Kentucky Equine Research (KER), this is a reasonable question but one that is easily answered.
“A horse's energy requirement stays the same during consistent work,” explained Pagan, “but sweat losses change with weather, work intensity, and other factors. Horse owners need to be able to easily adjust the amount of electrolyte given based on sweat production.”..Read More...
Changes in Horse Manure Consistency
Loose manure and diarrhea in horses typically stem from one of three causes: antibiotic therapy, diet, or disease. Because of excessive water loss associated with diarrhea, affected horses can become dehydrated and have other problems, so horse owners should investigate changes in manure consistency immediately, calling in a veterinarian if necessary.
Antibiotics are a well-known trigger for loose manure because they eliminate many of the innate and beneficial microorganisms that reside in the horse’s hindgut...Read More...
Microbiota of the Neonatal Foal
During the first few weeks of a foal’s life, the development of a diverse and healthy microbiota occurs. The microbiota, or population of beneficial microorganisms such as bacteria and protozoa, plays a major role in the proper function of the immune system and will serve to protect the foal from harmful pathogens as it matures. The microbial population is influenced by environment and diet. Most discussion surrounding the equine microbiota involves mature horses, and a closer look at a foal’s hindgut inhabitants provides interesting insight.
Foals are born with a sterile gut, but microbial colonization begins the first day of life. Some researchers found that meconium, the foal’s first feces after birth, is not sterile, while others report that it is. Differences may be attributed to the mare or sample collection techniques...Read More...
Maximizing Equine Health, Welfare Using GPS
Other than discretely observing your herd for hours on end in the rain, sleet, snow, or blistering heat at various hours of the day or night, how can you know if your horses are truly getting all the care they need? According to a group of Japanese researchers*, affixing global positioning system (GPS) units to halters of horses and tracking their movement generates important information for managing herds of all shapes, sizes, and compositions.
For example, the researchers used GPS units on mare-and-foal pairs to determine mare-foal, mare-mare, and foal-foal distances to better understand behaviors of broodmares. They found during the first month of age, dam–dam and foal–foal distances were significantly greater than dam–foal distances. This finding makes sense considering how frequently foals nurse during their first month of life. During the second month of age, the dam–foal distance increased, and by the sixth month of age, dam–foal distances were significantly greater than foal–foal distances. ..Read More...
Gastric Ulcers in Horses: Injectable Treatment in Development
The effects of equine gastric ulcer syndrome (EGUS) keep many horses from performing their best. Greater awareness of this has led horse owners to be more conscientious of management practices that optimize gastric health, including the use of FDA-approved treatments such as omeprazole and research-based nutritional supplements such as Rite-Trac.
A buildup of acid that is not buffered by saliva and feedstuffs can cause the development of gastric ulcers in horses which, in turn, can account for many roadblocks to well-being, such as inappetence, weight loss, dull coat, and sour disposition. A recent study* in Australia has suggested that a long-acting, intramuscular formulation of omeprazole (LA-OMEP) may suppress gastric acid for up to a week after administration...Read More...
Overweight Horses: How Much Hay Is Too Little?
To some horse owners, maintaining easy keepers on an appropriate diet requires incredible restraint. While owners may wish to turn their horses out in bountiful pastures, they know it’s best to limit intake and use the drylot or grazing muzzle instead. Likewise, caretakers who want to dish out just a few pounds of sweet feed refrain from doing so and offer a balancer pellet in lieu. When it comes to hay, these same horse owners know too much is not helpful, but how much is too little?
With a limited menu available for overweight horses, maximizing hay intake is important, said Catherine Whitehouse, M.S., a nutrition advisor with Kentucky Equine Research (KER). “Hay intake should be about 2% of body weight, if horses are receiving no other feed or forage.”..Read More...
Metabolic Syndrome in Horses: Use of Sweeteners Studied
Despite best efforts by owners to follow strict diet recommendations for horses with metabolic syndrome, some feeds and medications contain sweeteners, including certain medications used to counteract equine metabolic syndrome (EMS).
Horses with EMS are insensitive to the effects of insulin, typically overweight, and may suffer chronic bouts of potentially life-threatening laminitis...Read More...
Research on Algae for Horses with Ulcers
Treatment options and management strategies to help horses fight or prevent stomach ulcers exist, yet the ideal solution to ridding horses of these uncomfortable, niggling nuisances remains elusive. Could a high-algae supplement finally be the reprieve horse owners are looking for?
“Current options for handling ulcers, widely referred to as equine gastric ulcer syndrome or EGUS, include pharmaceutical drug administration, such as FDA-approved omeprazole products, nutritional supplements, and management changes,” remarked Kathleen Crandell, Ph.D., a Kentucky Equine Research (KER) nutritionist...Read More...
Five Tips for Avoiding Pasture-Associated Laminitis in Horses
Scores of horses will gorge themselves on that long-awaited lush, green pasture of springtime. As many of us already know, overgrazing grasses and legumes that are high in water-soluble carbohydrates puts horses at risk for laminitis—a painful, life-threatening condition of the hooves.
“Many horse owners are already aware that pasture-associated laminitis is particularly concerning for overweight horses and ponies, easy keepers, those with insulin resistance or equine metabolic syndrome, and horses and ponies with a history of chronic laminitis. It is important for owners to appreciate, however, that pasture turnout can trigger a bout of laminitis even in lean, nonobese horses with no history of laminitis,” says Peter Huntington, B.V.Sc., M.A.C.V.Sc., director of nutrition at KER Australia. ..Read More...
Improving Intestinal Motility in Horses
Measuring 100 feet or more in the average mature horse, the equine gastrointestinal tract serves many functions, all neatly compartmentalized:
The mouth chops and grind feed and forage into manageable pieces;
The esophagus transports ingesta from the mouth to the stomach;
The stomach further breaks down ingesta into minute particles that pass into the small intestine;
Some types of nutrients in the feed, such as nonstructural or water-soluble carbohydrates, proteins, fats, vitamins, and minerals, are digested and absorbed in the small intestine;
The remainder of the feed, primarily structural carbohydrates or fiber, pass into the cecum and large intestine, where they are fermented to form volatile fatty acids, a primary source of energy for the horse.
Any alteration in the proper functioning of this system can quickly become life-threatening. A large variety of disorders can decrease the ability of the gastrointestinal muscles to contract appropriately, delaying the movement of ingesta. Decreased motility, or hypomotility, can occur in cases of equine grass sickness, gastroduodenal ulceration, colic (e.g., obstruction, impaction, excessive wall distention, strangulating obstruction), inflammation of various regions of the gastrointestinal tract such as peritonitis, duodenitis, proximal jejunitis, and colitis...Read More...
