Have you ever wondered, can horse burp, or do their digestive systems work differently from ours? Unlike humans, who can easily release gas through a burp, horses have a unique and somewhat delicate digestive system that doesn’t allow this simple mechanism.
Their inability to burp stems from the structure of their esophagus and stomach, designed in a way that prevents food or gas from moving back upward.
This might seem like a minor detail, but it’s actually a critical aspect of equine health. Without the ability to burp, horses rely on their digestive efficiency to avoid bloating and discomfort. However, this design also makes them more susceptible to conditions like colic—a potentially life-threatening issue if gas builds up excessively.
Understanding this fascinating fact not only helps you care for your horse but also highlights why proper feeding and regular health checks are essential. Let’s dive deeper into how their digestion works!
Horse Digestive System
Unique Anatomy of Horses
Horses possess a distinctive and complex digestive system designed primarily for the slow, continuous intake of forage. Their digestive anatomy reflects their status as non-ruminant herbivores, meaning they do not have a rumen like cows but still rely heavily on fibrous plant material.
Cardiac Sphincter: One of the unique features of a horse’s digestive tract is the cardiac sphincter, a strong band of muscles located at the junction between the esophagus and the stomach. This sphincter only allows food and liquids to move one way—into the stomach—which is why horses cannot burp or vomit.
Stomach: The horse’s stomach is relatively small, holding only about 2-4 gallons. It is designed to function best with a constant supply of food, mimicking the grazing behavior of wild horses, which graze for up to 15 hours a day (KA-HI).
Hindgut Fermenters: Horses have a large cecum and colon where microbial fermentation of fibrous plant material occurs. This fermentation process allows them to digest and extract nutrients from the roughage that they consume.
Here’s a snapshot of the distinctive parts of the horse’s digestive system:
| Digestive Part | Function |
|---|---|
| Cardiac Sphincter | Prevents burping and vomiting |
| Stomach | Small capacity, initiates digestion |
| Cecum | Microbial fermentation of fibrous material |
| Colon | Further fermentation and water absorption |
Digestive Disorders in Horses
Despite their robust digestive system, domestic horses are prone to several gastrointestinal disorders primarily due to feeding practices that deviate from their natural grazing habits.
Colic: Colic is a general term for abdominal pain and can be caused by a variety of digestive issues, such as gas buildup, impaction, or twisting of the intestines. Colic is often related to the inability of horses to burp, which leads to trapped gas and painful distention (Quora).
Ulcers: Equine gastric ulcer syndrome (EGUS) is a common condition in horses, especially those undergoing intense exercise or irregular feeding schedules. Acid buildup in the stomach can lead to painful ulcers.
Laminitis: Overloading the foregut with non-structural carbohydrates (sugars and starches) from grain-heavy meals can lead to a condition known as laminitis, an inflammation of the laminae in the horse’s hooves.
Maintaining the digestive health of horses involves mimicking their natural diet by providing continuous access to forage and avoiding large grain-based meals. For more information on maintaining a healthy diet for your horse, refer to our section on maintaining digestive health.

Can Horses Burp?
Understanding Horse Digestion
Horses have a unique and complex digestive system that plays a key role in their overall health. Their digestive process is different from many other animals due to their herbivorous diet and the structure of their gastrointestinal tract. Unlike ruminants like cows, horses have a single-chamber stomach. This means their digestion relies heavily on the fermentation process in the cecum and colon, which is where a significant portion of their feed is broken down.
The process begins in the mouth, where horses chew their food thoroughly, mixing it with saliva to aid in digestion. The food then travels down the esophagus and into the stomach, where the cardiac sphincter comes into play. This is a special valve that ensures food only moves in one direction – from the esophagus to the stomach.
Factors Preventing Burping
The inability of horses to burp is primarily due to the function of the cardiac sphincter. This valve is designed to allow food and liquids to enter the stomach while preventing anything from refluxing back up into the esophagus. As a result, this one-way system not only stops horses from burping but also from vomiting (Quora).
Here are key reasons why horses cannot burp:
Cardiac Sphincter Function: The cardiac sphincter between the esophagus and stomach only permits one-way flow, stopping any gas or food from coming back up.
Gastric Pressure: If the stomach is distended with gas, the pressure is relieved not by burping but rather through the lower digestive tract. Excessive gas build-up can lead to colic, a severe and sometimes life-threatening condition.
Evolutionary Adaptations: Horses’ digestive systems are adapted to their feeding habits, which involve continuous grazing on fibrous plant material rather than rapid intake of large meals (Quora).
This specialized digestive system means that while a horse cannot burp, they can exhibit a form of belching if gas becomes trapped. However, in cases where excessive gas accumulates, horses are at risk for conditions like colic, requiring immediate veterinary intervention.

Maintaining Digestive Health
Importance of Forage in a Horse’s Diet
Forage is a critical component of a horse’s diet, vital for maintaining digestive health. Horses evolved on a diet primarily consisting of forage like grass, which is easily digested and provides the necessary fiber for proper gut function. Experts recommend that a horse’s diet should be comprised of at least 50% forage (Ohio State University Extension).
Wild horses, which graze for over 15 hours a day, rarely suffer from digestive issues such as colic or ulcers. This is in stark contrast to domesticated horses, which can experience these problems due to insufficient forage intake (KA-HI). Forage provides the essential long-stemmed fiber horses need to produce volatile fatty acids, necessary for energy and efficient digestion.
To avoid digestive issues, it’s best to ensure that your horse has constant access to quality forage. This helps to maintain the natural passage rate or the flow of feed through the gastrointestinal tract, aiding in efficient nutrient absorption and usage.
Effects of Feeding Practices
Feeding practices have a significant impact on a horse’s digestive health. Domesticated horses are often fed in ways that deviate from their natural grazing behavior, which can lead to issues like colic and gastric ulcers. Feeding large, grain-based meals infrequently can overload the foregut, increasing the risk of digestive disorders (Ohio State University Extension).
| Feeding Practice | Potential Issue |
|---|---|
| Large, infrequent grain-based meals | Increased risk of colic, laminitis, and ulcers |
| Small, frequent forage-based meals | Maintains stomach pH, reduces ulcer risk |
To mitigate these risks, it is advised to feed horses small, frequent meals of forage throughout the day. This feeding strategy mimics their natural grazing habits and provides a buffering effect that keeps stomach acid levels in check, maintaining a stable pH above 4.0.
Overloading the diet with non-structural carbohydrates (NSCs) by providing large grain meals can lead to negative consequences. Such feeding practices can trigger digestive upset, including colic and laminitis, because the horse’s gastrointestinal system struggles to handle the sudden influx of grain, which is high in NSCs.
In summary, understanding the importance of forage and adopting appropriate feeding practices is crucial for maintaining the digestive health of horses. By prioritizing forage and avoiding large grain-based meals, you can help prevent common digestive issues and ensure a healthier, happier horse.

Diarrhea in Horses
Causes of Diarrhea in Horses
Diarrhea in horses can be caused by a variety of factors, including bacterial or viral infections, parasites, and dietary changes. Understanding these causes can help in identifying and treating the condition effectively.
Infections: Neonatal foals are especially susceptible to bacterial diarrhea caused by organisms such as Salmonella, Clostridium species, Escherichia coli, and Lawsonia intracellularis. Viral infections can also lead to diarrhea in horses (Merck Veterinary Manual).
Parasites: Parasites like strongyles and tapeworms can cause gastrointestinal issues, including diarrhea. Regular deworming schedules are essential for preventing parasite-induced diarrhea.
Diet: Abrupt changes in diet, poor-quality feed, or the ingestion of large amounts of sand can lead to diarrhea. Horses kept on sandy pastures or fed hay or grain in sandy areas may inadvertently consume sand, resulting in diarrhea and other digestive issues (Merck Veterinary Manual).
| Cause | Common Triggers | Signs & Symptoms |
|---|---|---|
| Infections | Bacteria (Salmonella, Clostridium), viruses | Diarrhea, fever, lethargy, colic |
| Parasites | Strongyles, tapeworms | Diarrhea, weight loss, poor coat |
| Diet | Sudden dietary changes, sand ingestion | Diarrhea, colic, weight loss |
Treatment and Management of Diarrhea
Managing diarrhea in horses involves addressing the underlying cause, providing supportive care, and preventing recurrence.
Medical Treatment: For bacterial infections, intensive antibiotic treatment is often required. Fluid therapy and electrolyte replacement are crucial for maintaining the horse’s health during treatment. In cases of parasitic infections, an appropriate deworming regimen should be followed.
Dietary Adjustments: Introducing dietary changes gradually can help prevent diarrhea. Adding a fiber product, such as psyllium seed hull, to the feed can help manage sand ingestion by aiding in its expulsion from the digestive system. Feeding horses off the ground and on clean, grassy areas can reduce the risk of sand ingestion (Merck Veterinary Manual).
Supportive Care: Providing clean, fresh water and ensuring the horse has access to good-quality forage can help maintain digestive health. Isolation may be necessary for horses with infectious diarrhea to prevent spreading to other horses.
