When Is The Best Time To Give Gastrogard

Myth busting Hindgut Ulcers with world expert on equine gut health Associate Professor Dr Ben Sykes

If youre treating a horse with GastroGard, Slovis recommends giving it to the horse on an empty stomach. Research has shown in animals that if you give GastroGard on a full stomach, you might not get the increase in pH that you want because the stomach doesnt absorb it as well on a full stomach, he said.

Hindgut Disturbances Fecal Consistency Problems And Associated Risks

First, what constitutes a hindgut disturbance? This includes a wide range of symptoms and signs, affecting a variety of organ systems and tissues, with both acute and chronic onset versions.

Chronic DisturbancesTypical chronic/more mild indicators for disturbances of the GI tract include gas, bloating, loud and/or frequent gut sounds, and abnormal fecal/defecation characteristics, such as changes in: defecation frequency , fecal size , fecal consistency , fecal color , fecal smell , presence of feed or forage particles, signs of parasites or foreign objects, etc. With chronic disturbances, overall health of the horse can suffer, as digestion and/or absorption can be impaired. Signs of this can include low body condition despite adequate feed intake, dry/dull coat, poor hoof quality, lack of energy, slow to heal from wounds/injuries, etc. Often, these chronic signs are related to diet, parasite load, stress, hydration, or even dental problems . If you are concerned about hindgut disturbance behaviors, reach out to your veterinarian or your to discuss the problems to determine ways to help your horse.

Especially if this cycle continues with an unstable diet and weakens the population of microbes that aid in digestion, ultimately more dangerous microbes may be able to grow their numbers, increasing the changes of a pathogenic infection developing.

What Are The Clinical Signs Of Gastric Ulcers

The majority of horses with gastric ulcers do not show outward clinical signs and can appear completely healthy. Subtle signs may include:

  • Poor appetite
  • Low grade colic
  • Girthiness

More serious cases will show abdominal pain and/or grinding of the teeth. Some horses are found on their backs since this position seems to provide some relief from severe gastric ulceration. Others will walk away from food if they experience discomfort when the food first reaches the stomach.

Clinical signs of ulcers in foals include intermittent colic , frequent recumbency, reduced nursing, diarrhea, poor appetite, a pot-bellied appearance, grinding of teeth, and excess salivation. When a foal exhibits clinical signs, the ulcers are likely to be severe and should be diagnosed and treated immediately.

Signs That Your Horse Might Have An Ulcer

Ulcers in horses can be challenging to identify as they sometimes present with quite generic symptoms. Only veterinary diagnosis will confirm whether your horse has ulcers or not but what are the telltale signs that you should keep an eye out for? Read our handy guide and become better informed.

Ulcers can present with a range of symptoms that can easily be attributed to other conditions. If you suspect something is wrong then your vet should evaluate your horse as it could be ulcers or a different issue. Ulcers rarely heal on their own without veterinary intervention. If your horse does have ulcers, your vet will need to determine which type they are as there are two different classifications:

  • ESGUS Ulcers in the upper region of the horses stomach which is called the Squamous, really the lower end of the oesophagus lining and the most common of the two types of ulcer
  • EGGUS Ulcers in the lower glandular region of the horses stomach

These are some of the symptoms a horse with ulcers can exhibit:

  • Resistance when ridden this can manifest in lots of different ways and maybe subtle and inconsistent right through to an obvious change of behavior. It is important to make sure there are no other underlying causes which could be contributing to a behavioral change such as a saddle fitting issue, a sore back or even a change of rider to someone less competent.
  • The Hindgut Bacterial Populations

    Home Remes For Gastric Ulcers In Horses

    There are three major groups or families of bacteria in your horses hindgut. These are:

    1. The fibre fermenters

    2. The starch and sugar fermenters

    3. Lactate utilising bacteria

    When a horse is eating a low sugar, low starch diet that is high in fibre the fibre fermenting bacteria dominate the hindgut bacterial populations. These little critters ferment fibre efficiently yet slowly and do a wonderful job of providing a horse with calories and vitamins, all the while keeping the hindgut environment at a lovely stable pH, very close to neutral.

    When large amounts of starch or sugars like fructan are suddenly dumped in the hindgut however, the starch and sugar fermenting bacteria essentially have a party and go to town rapidly fermenting their newly arrived favourite foods. Their population increases rapidly in numbers and the lactic acid they produce starts to accumulate, lowering the pH in the hindgut environment. If the starch and sugar continues to be delivered to the hindgut they can drop the hindgut pH so low that the fibre fermenters, who dont like acidic environments, will begin to die off .

    HOWEVER, the safety catch doesnt always work. First, a study byBiddle et al. found that the bacterial populations in different horses react very differently under the same conditions. Specifically they showed that some horses simply may not have a useful increase in lactate utilising bacteria when starch and/or lactate are provided for their bacterial populations to ferment.

    Introduction To Equine Colonic Ulceration

    Gastric ulceration in performance horses is a common and a well-recognized problem, which can be diagnosed by gastroscopy. Performance horses may also be at risk of developing colonic ulcers, however colonic ulcers are more difficult to diagnose, as the colonic mucosa cannot be easily visualized. The large colon cannot be completely examined without exploratory surgery or necropsy.

    Pellegrini conducted a study that revealed how prevalent colonic ulceration actually may be. Dr. Pellegrinis study is currently the only published, large-scale research that has been performed on this disease. The study was performed at a Texas abattoir, and involved the necropsy of over 500 horses. One hundred and eighty of these horses were known to be performance horses, and colonic ulcers were found in 63% of these horses . In the remaining group of horses, 44% had colonic ulcers and 55% had gastric ulcers.

    Given that these horses were presenting to an abattoir, the study results do not necessarily reflect the general horse populations, and the reasons for the horses being taken for slaughter were not always available. However, the prevalence of gastric ulcers in the performance horses in this study did approximately reflect the upper limit of what we now know about the prevalence of gastric ulcers in performance horses, and so it gives some credence to the fact that the prevalence of colonic ulcers may be higher than was previously thought.

    Signs And Symptoms Of Hindgut Ulcers

    Horses experiencing hindgut ulcers can have varying signs and symptoms. Some of these overlap with . It is important to consult with your veterinarian to evaluate which type of ulcer your horse has or whether they have both.

    Early signs often include mild, intermittent or recurring colic, lethargy, and/or loss of appetite. As the condition progresses, more symptoms may appear. These symptoms may include:

    • Sudden girthiness
    • Sensitivity in the flank area
    • Difficulty bending, collecting, and extending
    • Blood in the manure
    • Chewing wood

    A horse experiencing hindgut ulcers may experience acute symptoms or they may experience chronic symptoms.

    In acute cases, a horse may have fever, depression, loss of appetite, colic, and/or watery diarrhea. They may also experience free fecal water syndrome . The horse may be dehydrated and have deterioration of the mucous membranes .

    Horses experiencing chronic Right Dorsal Colitis may exhibit weight loss, recurring low-grade colic, swelling along the central midline of the belly, and/or loose manure.

    Blood work for these horses may show protein loss or low albumin levels . In one study, four horses with symptoms of hindgut ulcers were examined and displayed both of these markers.

    Other changes in blood work may include high levels of white blood cells and/or low calcium levels.

    Equine Ulcers Signs & Symptoms

    How can you tell if your horse has ulcers? The only definitive way to diagnose EGUS in your horse is by having a veterinary checkup to perform a gastroscopy.

    Your vet will look into your horses stomach and upper intestine with an endoscope to see whether there are ulcers present, how severe they are and their location.

    But even without an exam by your vet, there are some common signs and symptoms to look out for as evidence that your horse may have ulcers. If you think your horse is affected, a visit from the vet to perform a scope is warranted.

    Signs and symptoms of gastric ulcers in horses are generally non-specific and can vary greatly between horses. Many horse owners note that their horse is just not looking right.

    Some common symptoms include:

    • Poor appetite or picky eating
    • Poor body condition or weight loss
    • Chronic diarrhea

    Symptoms of Gastric Ulcers in horses?

    Your horse is groomed to a higher glow, hoofs selected, hair perfectly combed. Now it is here that we are at negligence the adding process youve been dreading: saddling. Whenever you go to the band on the thickness, regardless of how carefully you are, your horse hooks his hearing, attacks at you, and maybe even intends to punch. In severe circumstances, he brings himself to the floor in the cross ties. All of these actions are terrifying and risky for both of you.

    Having a girthy horse is a regular issue for many horse owners. Most of the time your horse came to you in such manner. Sometimes he suddenly developed girthiness later in your relationship. Either way, you really cant figure why.

    Here are the very three essential factors why horse creates girthiness. With the assistance of your vet and a qualified trainer, you can use the process for removal to ascertain which issue is resulting in your horse to be girthy the starting point in solving it.

    Can Ulcers In Horses Cause Diarrhea

    Chronic Diarrhea

    They can also develop diarrhea with certain illnesses such as salmonellosis or coronavirus. However, chronic diarrhea may be a symptom of ulcers. Researchers arent sure exactly why this occurs, but it has been reported widely enough that it is accepted as one of the clinical signs of ulcers in horses.

    Tail Swishing Whilst Eating

    Tail swishing during feed consumption is very atypical for healthy horses and a clear sign of gastric ulcers.

    Tail swishing is a sign of pain and discomfort.

    The horse experiences pain through the consumption of food and its subsequent digestion and responds by swishing its tail.

    Problems In The Hindgut

    Horses can experience a wide variety of hindgut health issues, ranging from diarrhea to torsion colics. However, according to Russillo, the most commonly occurring hindgut health issue in the performance horse is colonic ulcers, which are the focus of this article.

    Colonic ulcers are the number-one thing I deal with in my patient population, she says. Other issues that can pop up include infectious causes of diarrhea , large bacterial shifts in the colon caused by orally administered antibiotics and dietary intolerances . But by and large, the thing that were day in, day out screening for in the performance horse is definitely going to be could this horse have colonic ulcers? Russillo says.

    How Common Are Colonic Ulcers

    Ulcers are a common issue in performance horses. Russillo references a study performed in 2005 by Franklin L. Pellegrini, DVM, that examined the presence of colonic ulcers in horses at necropsy. What could be concluded, based on the study, according to Russillo, is that somewhere between 44 and 60 percent of horses have some level of colonic ulceration, with a higher percentage in performance horses. Stomach ulcers are still more prevalent, she says. But hindgut ulcers are definitely a real thing and worth having conversations with owners about.

    Equine Colonic Ulcer Syndrome

    Whereas equine gastric ulcers are found in the stomach, colonic ulcers are lesions that occur in the hindgut . A horse is a hindgut fermenter, meaning it ferments forage in its colon to create Volatile Fatty Acids , which produce the majority of a horses energy. Because the hindgut is where most of the horses digestive process takes place, it is vital to overall equine health.

    Colonic Ulcers In Horses: Ulceration In The Hindgut

    Gastric ulcers have been in the spotlight in recent years, thanks to well-known treatment and extensive research in this area. As a result, many people associate equine digestive health with stomach health. But truly understanding the horses digestive system means understanding the significance of the hindgut.

    This attention to gastric ulceration is ironic, if not downright detrimental. The stomach represents less than 10% of the total volume of the digestive tract. On the other hand, the hindgut is huge and vital to the horses digestive process and overall health. Most importantly, it is the home of a huge bacterial environment that converts fiber to energy the horse is known as a hindgut fermenter, meaning it obtains most of its energy by fermenting forage in its colon.

    Because the hindgut plays such a critical role in digestion and health, it may also be the source of so many of the problems we are seeing.

    Thanks to extensive research by Franklin L. Pellegrini, DVM, we now know that hindgut ulcers do exist. In fact, they are rather common. Colonic ulcers, or lesions found in the colon, predominantly affect performance horses and are frequently identified in horses already suffering from gastric ulcers.

    Symptoms Of Hindgut Ulcers In Horses

    If all this is happening inside the horses digestive system, how can we tell from the outside? Usually, when digestive problems occur, absorption problems follow soon after. You will typically notice things like decreased appetite, diarrhea, weight loss, poor performance and even colic.

    Other symptoms are less obvious, such as reluctance of the horse to flex, extend or collect, and heightened sensitivity on the flanks. Lack of focus, poor temperament and training issues are also common. How do you expect the horse to concentrate under these conditions?

    Treatment and Prevention

    The obvious answer to all these problems is to drastically change how we feed and care for the animal and to get closer to the way the horses digestive system was intended to work. This means more pasture, more forage and adopting habits such as feeding the horse small amounts of food multiple times a day. Other changes include limiting starch and reducing the amount of stress we subject them to.

    Equine supplements can also help a horse who is suffering from hind gut problems. At Kauffmans Animal health, we sell a variety of supplements that can help horses who are suffering from hind gut ulcers. These supplements include Digest-Mor, Equine laxative, KA-HI Pro Paste, Kauffmans Digestive Health, Kauffmans Equine Gold, and Kauffmans Summit.

    Etiology And Pathophysiology Of Colonic Ulcers In Horses

    Gastric ulcers and colonic ulcers can both occur secondarily to NSAID administration. Phenylbutazone, administered at high doses, or over a long period of time, poses a particular risk. Phenylbutazone is one of the more commonly used NSAIDs for musculoskeletal pain in horses, and it is a non-specific COX inhibitor, the combination of which contributes to phenylbutazone being closely associated with RDC development. Many NSAIDs can induce RDC, including the COX-2 selective inhibitors such as meloxicam, but this usually only occurs when administered at doses well above the recommended dose.

    Some horses are thought to be more sensitive to the side effects of NSAIDs and can develop ulcers at lower doses. Whether some of these horses have an underlying disease that predisposes them to RDC is not known .

    Ulceration tends to be worse in the right dorsal colon, however other parts of the large colon may also be affected. Researchers are currently considering the possibility that colonic ulcers may also occur in the absence of NSAID administration.

    Possible, but unproven, causes of non-NSAID-induced colonic ulceration include:

    • Acidosis of the hindgut from fermentation of carbohydrate-rich foods ,
    • Helminth migration or encystment in the colon wall,
    • Chronic stress resulting in chronically high endogenous plasma cortisol concentrations.

    A combination of these factors is also a possibility.

    What Causes Ulcers In Horses

    If you suspect your horse has ulcers then the first thing you should do is call your vet. They will usually scope your horse to see if there are any visible in your horses stomach. Your horse may also have hind gut ulcers which cannot be seen with a scope.

    Ulcers are caused when there is too much acid present in the stomach. They are grazing animals which means their bodies are programmed to have a constant trickle of food, and subsequently their stomach constantly secretes acid.

  • Dislikes being brushed, especially in their abdominal area
  • Changes in behaviour, such as biting, cow kicking, cold backed
  • Drop in performance
  • I frequently get called out to horses that exhibit the symptoms below, as they are similar to those that suggest back pain. If I suspect ulcers then I will refer you back to your vet for diagnosis. McTimoney Horse Chiropractic cannot cure ulcers, but if your animal is stressed for muscular discomfort, a treatment schedule along with veterinary care will help them feel better.
