There's no cure-all for equine gastric ulcer syndrome, but proper management and prevention methods can help your horse remain ulcer-free .

What could the following three situations all have in common?

You return home from a horse show after a disappointing weekend. Your elite performance horse, usually high in the ribbons, did not place well. He occasionally looks at his sides and appears uncomfortable. You have a young, excitable filly that was recently weaned. A normally robust and outgoing foal, she is now standing in her stall, uninterested in either interacting with humans or eating her grain. Your mature gelding that lives on lush pasture recently went through a mild bout of laminitis. He's always been a stoic fellow and rarely shows when he's in pain. Now, his hair coat is dull, and he seems to be "depressed." What might be surprising to some is that while these clinical signs could point to a number of problems, all three of these horses could be diagnosed with the same condition: equine gastric ulcer syndrome.

History and Signs

Equine gastric ulcer syndrome includes not only ulcers found within the stomach (usually in the esophageal region, or upper portion), but also ulcers found at the duodenal part of the small intestine, which is the portion closest to the stomach. Ulcers occur when the pH of these gastrointestinal tract areas becomes too acidic, and cells of the lining are damaged. The primary acid of digestion in the stomach, hydrochloric acid, is produced and released continuously into the stomach of the horse, unlike in humans, where it is produced only when food is present. Horses produce almost 1.5 liters/hour of this acid because they have evolved as continuous eaters, or grazers...

Soaking Hay: How Effective Is it at Lowering Carbohydrates?

Equinews.com - Full Article

By Kentucky Equine Research Staff · February 3, 2012

If your horse needs a low-carbohydrate diet, you can reduce the sugar concentration in hay by soaking it in water prior to feeding. While this has nearly become common knowledge, there is a lot of confusion about the best procedure to follow. How long do you soak the hay? In hot water or cold? By the half-bale or the fluffed-up flake? How much sugar is actually lost? And do all types of hay respond the same way to soaking? A study in England revealed some answers.

Nine types of hay were used in the study, and widely varying results were found between the types. Water-soluble carbohydrates (WSC) including fructans, glucose, fructose, and sucrose can be dissolved by soaking in either hot or cold water, though they dissolve more quickly in hot water. This study used cold water for periods of 20 minutes, 40 minutes, three hours, or 16 hours...

Starting the Endurance Horse Prospect - Part 1

Hought.com - Full Article

by Eric Hought

The commonly accepted practice of starting the purebred or part Arab endurance horse prospect at ages 4-6 years is one for debate. The main concern: are the legs properly developed to support a rider’s weight.

Much can be done with the young horse at 2-3 years of age as long as the rider uses common sense and safe practices. Groundwork is very important. There are many methods available from today’s clinicians, so select an approach from one whose methods best fit your preferred style of preparing the horse.

No harm will be done through groundwork, saddling, ponying and standing tied to “soak” for a couple of hours. It goes without saying the facility must be safe for a horse standing tied before and after a ride. The use of leg protection is the rider’s option. The girth should be pulled only as snug as needed so the saddle will not turn while the horse is tied and moving around.

Why stand tied? The horse learns patience and to wait for the leader. I saddle and stand my young horses for up to 2 hours per day for at least 4-5 days per week. Look for the horse to demonstrate that this practice has become “just what we do.” This is a valuable routine he will experience for the remainder of his life. He may not be tied as long at home, but there will be times in the future in unfamiliar settings where having learned this patience will help him manage the situations and time factors.

This is how I start 2 year olds. I give each horse my total focus and commitment. Typically, I saddle and stand him a couple of hours before I ride. I will usually do this before each ride for about 3-4 months. By the 3rd month of riding, standing saddled for an hour is fine.

I ride at the walk with some trotting for 60-90 days. During this time, I focus on foot, face and body control. When I am riding in an arena, I time each ride for exactly 15 minutes. The short time factor keeps the horse’s mind working and avoids boredom for both horse and rider. I am fortunate to have access to riding areas outside the arena on dirt roads, single track trails, hills, uneven ground, walkovers and water crossings. These rides are about 1-1 1/2 hours. I am careful not to do any sustained trotting on any unprepared surface because it takes time and miles to begin to develop leg fitness. This is by far the best setting for starting young horses. Of course I do not just sit like a sack of potatoes. I work on foot, face and body control. Leg and body development are occurring simultaneously while keeping the rider’s and horse’s minds working...

Researcher Evaluates Bit, Rein Interaction with Equine Mouth

Thehorse.com - Full Article

by: Christa Lesté-Lasserre
April 13 2012, Article # 19877

Having a better understanding about the mechanics of riders' hands' interactions with the horse's head can improve your horse's performance, comfort, and well-being, noted one researcher at a recent equitation science conference. Hilary M. Clayton, BVMS, PhD, Dipl. ACVSMR, MRCVS, Mary Anne McPhail Dressage Chair in Equine Sports Medicine at Michigan State University, explained that bits, nosebands, and headpieces all exert pressure on horses when we place pressure on the reins, which can vary considerably.

But new biomechanical findings in equitation science can help riders make more informed decisions about equipment use and also dispel certain myths about bridles, bits, and reins.

According to Clayton, soft tissues such as the tongue, for example, are better suited to handling pressure than hard tissues like the nose bone and the palate (the roof of the horse's mouth). "The horse's tongue can be very sensitive but it can also withstand a lot of different kinds of pressure," she said during her plenary lecture at the 2011 International Society for Equitation Science Conference, held Oct. 26-29 in Hooge Mierde, The Netherlands.

"From my point of view, I would be a lot more concerned about pressure directly on the hard tissues (and) the bones, rather than the soft tissues which have a lot more ability to absorb the forces," she said.

Using radiographs (X rays) and fluoroscopy (real-time radiography) of a horse's head while wearing a bridle and bit, Clayton evaluated the position of the bit in a horse's mouth with and without tension applied to the reins...

Round Bale Feeder Design Affects Hay Waste and Economics

Equinews.com - Full Article

By Dr. Kathleen Crandell · February 13, 2012


Using round-baled hay is attractive to horse owners because this forage form is less labor-intensive, more convenient, and less expensive than feeding hay in square bales. Some of the drawbacks are excessive hay waste, overconsumption, and weight gain among horses. Several round-bale feeders have been designed to address some of the drawbacks, especially wastage of hay, but to date there have not been any published comparisons.

Researchers in Minnesota conducted an experiment that would measure hay wastage from nine round-bale feeders of differing designs as well as the economics of how long it would take before the feeder would pay for itself in savings related to less wasted hay.

Twenty-five mature Quarter Horse and Thoroughbred mares and geldings with free-choice access to water and a trace-mineralized salt block were fed orchardgrass round bales in nine different commercial round-bale feeders. To test the feeders, the horses were divided into groups of five and then exposed to one of nine different round-bale feeders, or the control of no feeder, for four days. When the horses were switched to a different feeder, they received a new round bale. During the time each group was housed with the hay in the feeder, all the hay on the ground was collected daily, and at the end of four days all the hay left in the feeder was dried and weighed...

More Debate on Beet Pulp: Is it Toxic?

Equineink.com - Full Article

December 13 2009
Posted by Liz Goldsmith

I like it when people comment on my posts. Sometimes they agree; others have challenged what I’ve found and caused me to do more research. A question from a reader prompted me to look into whether feeding whole flax seed was indeed a good idea and resulted in, Update on Feeding Flax Seed.

So, when I received this comment on Beet Pulp: Fact & Fiction, I thought it deserved to be answered.

I felt I had to add a post because I do not agree with it. First of all I and my family have been breeding, racing and competing horses for generations. I would never recommend or use beet pulp one of the reasons why is because of the process it goes through. When seperating (sic) the sugar from the pulp chemicals and bleaches are used ie. it is the whitening process, and the left over scrap is the pulp. I love my horses and I would never feed them this. I give my horses natural products that are not GM and no chemicals thank you. Alfalfa pellets/bales, Carob, Hay, and fruit treats are a great way to feed your horses naturally! There is also very little nutritional value in Beet and it is only a filler. If you cannot afford to buy the right natural products for your horse then you should not have a horse. I have never had a problem with any of my horses, and they also keep their teeth to a good old age.

I’ve seen some of this before . . . especially the “just a filler” argument. To be honest, I’d never thought about whether processing the beet pulp left a chemical residue. So, I started to do some research. I think I found where this person got their information.

In my search I came across another condemnation of beet pulp from Lorrie Bracaloni. Readers might remember that I recently reviewed her DVD and Workbook “How to Identify and Release your Horse’s Pain Points.” Her article is entitled, Is Beet Pulp Toxic to Horses? The Real Story. In it, she re-iterates the issue about pesticides but adds some additional claims that make beet pulp look like the absolute worst feed possible...

Feeding Beet Pulp

Thehorse.com - Full Article

by: Karen Briggs
May 01 1999, Article # 314

Q: I've been told I should feed beet pulp to help put weight on my skinny Thoroughbred. But I'm worried about the stories I've heard about beet pulp expanding in the horse's stomach and causing colic -- or worse! Is beet pulp a good addition to my horse's diet, and if so, how can I feed it safely?

A: Beet pulp is the fibrous material left over after the sugar is extracted from sugar beets. It's an excellent source of digestible fiber, with a relatively low crude protein content (averaging 8 to 10%), comparable to good-quality grass hay. Its digestible energy is somewhere between that of hay and grain. In terms of other nutrients, it's not a stand-out--it has a relatively high calcium content and very little phosphorus, is low in B vitamins, and has virtually no beta-carotene (the precursor of vitamin A) or vitamin D. Its chief value is as a soft, easily digestible supplement to your horse's roughage (fiber) intake, and as such it's a useful addition to the diet of many types of horses.

Consider feeding beet pulp if your horse is a "hard keeper" (it's very good for encouraging weight gain), if he has dental problems that make chewing hay difficult, if the quality of your hay is poor, or if you have a geriatric horse who has trouble chewing or digesting other types of forage. It can be fed in addition to, or instead of, hay. Beet pulp's excellent digestibility also makes it a great choice for a convalescing horse--one recovering from illness or surgery, for example. It even can be fed warm in the winter months, just like a bran mash (and nutritionally, it's a better choice than bran)...

Equine Electrolyte Use and Gastric Emptying (AAEP 2011)

Thehorse.com - Full Article

by: Nancy S. Loving, DVM
March 15 2012, Article # 19740

A horse’s prolonged sweating during athletic activity or travel means a need for fluid and electrolyte replacement, and horse owners commonly turn to electrolyte products for this purpose. A team of equine researchers examined one electrolyte supplement’s (ES) effect on fluid replacement and performance, and Michael Lindinger, PhD, associate professor at the University of Guelph, presented the results at the 2011 American Association of Equine Practitioners convention, held Nov. 18-22 in San Antonio, Texas,

Dehydration significantly impacts the cardiovascular system, exercise performance, and recovery, as well as affecting thermoregulation (the horse’s ability to cool its body during exercise). Dehydration also affects mental acuity. Thus, effectively replacing fluids lost through sweating is of utmost importance in maintaining peak levels of health and performance. Lindinger pointed out that horse sweat contains significant concentrations of ions, such as sodium, potassium, chloride, calcium, and magnesium and these are sustained during exercise...

Does Your Horse Really Need A Low-Starch Diet?

Equinews.com - Full Article

By Dr. Kathleen Crandell · May 4, 2011

Horses derive dietary energy from a multitude of sources. A combination of fiber, starch, and fat is generally the best way to fuel performance, whether it is in the breeding shed, on the trail, or in the show ring. Over the last several years, the market has become flooded with low-starch feeds, and horse owners are responding by purchasing more and more.


Yet, low-starch feeds are not appropriate for every horse. Certain groups of horses require starch for optimal performance—growing youngsters and many equine athletes, for example. What lies behind the current low-starch craze?

What is starch?

Starch is a long, complex chain of sugar molecules. Within the plant, it represents the energy storehouse and is found in particularly high levels in grains. Starches are considered nonstructural carbohydrates because they are found within the cell wall. Fiber, on the other hand, is considered a structural carbohydrate because it lends support to the plant.

During digestion starch is broken down by enzymes into minute sugar molecules so that it can be readily absorbed. At this point, starch and sugar in the diet are handled similarly. Sugar in the diet can come from the cell contents in grass, molasses from feeds, and certain treats. These sugar molecules cross into the bloodstream and end up as glucose, which gets distributed to cells for use as energy throughout the body. The hormone that helps clear glucose from the blood and into the cells is insulin. This distribution method of getting glucose to the cells for energy, glycogen-building, or adipose storage is part of the energy-generation system of the working horse. The harder the horse is working, the more important the system is...

New Insulin Resistance Test Method for Horses (AAEP 2011)

Thehorse.com - Full Article

by: Nancy S. Loving, DVM
March 20 2012, Article # 19759


An obese horse is often—though not always—an insulin-resistant one, and detection methods for insulin resistance can be tricky to time, not to mention labor-intensive. François R. Bertin, DVM, a resident at the Purdue University College of Veterinary Medicine Teaching Hospital described a new testing technique that he has found useful for identifying insulin-resistant horses at the 2011 American Association of Equine Practitioners convention, held Nov. 18-22 in San Antonio, Texas.

The pancreas' beta-cells are responsible for secreting insulin to stimulate glucose uptake by glucose receptors. The glucose is moved into muscle cells where it is either used immediately or stored as glycogen for later access. An insulin-resistant (IR) horse has a decreased sensitivity to insulin (as a result, higher amounts of insulin are released than normal in response to ingestion of starch and/or sugar) along with a decreased maximal response to this hormone. High levels of circulating insulin in the bloodstream could put such a horse at risk for development of laminitis.

The recommended insulin-response test requires a veterinarian to take several blood samples over four hours. Bertin described an alternative testing procedure able to produce information on suspect IR cases, especially those horses with equine metabolic syndrome (EMS). While a cresty neck and fat pads at the base of the tail can be signs of EMS and indicative of a probably IR case, he emphasized that a definitive test is necessary for an accurate IR diagnosis...

A New Navicular Vantage

Thehorse.com - Full Article

by: Nancy S. Loving, DVM
January 01 2012, Article # 19415

Technological advances such as MRI have given veterinarians a closer look at navicular syndrome.
The great thing about technological advances is that they provide new perpectives on old problems. Magnetic resonance imaging (MRI), for instance, has given equine veterinarians an improved vantage point for examining the underlying disease process in navicular syndrome cases. Historically, the term navicular syndrome referred to lameness resulting from pain in the podotrochlear apparatus in the back of the foot that includes the navicular bone, bursa (sac cushioning the navicular bone from the deep digital flexor tendon), supportive ligaments, and deep digital flexor tendon.

"Everybody used to think that navicular disease meant the problem related to degeneration in the bone and surrounding structures. That's because on radiographs all we could see was the bone," explains Robert Schneider, DVM, Dipl. ACVS, professor and equine orthopedic surgeon at Washington State University's College of Veterinary Medicine.

Veterinarians began recognizing, however, that this process involves more than just the navicular bone. The lameness that started out being called "navicular disease" was renamed "navicular syndrome" and later called "caudal heel syndrome."

"Even still, there were a variety of treatment failures and opinions about what and why things happen and how and why to treat this 'syndrome,' including various shoeing strategies," says Stuart Shoemaker, DVM, Dipl. ACVS, owner of Idaho Equine Hospital, in Nampa...
