The digestive tract of a horse is remarkably long to process the large amounts of fibrous food they consume. The intestine is very long, and the cecum and colon are large and sacculated, which means they have many blind pockets. This extensive system allows for the maceration, fermentation, and dissolution of fibrous portions of the horse’s diet.
How Long is a Horse’s Digestive System?
The horse’s digestive tract is about 22 to 25 feet (6.7 to 7.6 metres) long. The stomach, however, is small, holding only about 8.5 percent of the entire digestive system’s capacity.
What Makes the Horse Digestive System Unique?
Horses are herbivores, and their digestive systems are specially adapted to process plant matter. Unlike ruminants, such as cattle, horses have a simple, undivided stomach. Instead, they rely on an extensive hindgut fermentation process in the cecum and colon to break down fibrous materials.
What are the Main Parts of a Horse’s Digestive Tract?
The main parts of a horse’s digestive tract include:
- Stomach: A small, simple stomach where initial digestion occurs.
- Small Intestine: A long, narrow tube where most digestion and absorption take place.
- Cecum: A large, blind sac where fermentation of fibrous materials occurs.
- Colon: A large, sacculated structure where further fermentation and water absorption take place.
How Does Food Move Through a Horse’s Digestive System?
Food moves through the horse’s digestive system through a combination of muscular contractions and enzymatic action. Peristaltic waves move the food along the digestive tract, while digestive enzymes break down the food into smaller, absorbable molecules.
What Special Considerations are there for Feeding Horses?
Horses should be fed high-quality forage, such as grass and hay, to ensure proper digestive function. Moldy or dusty feeds should be avoided because horses are susceptible to forage poisoning and respiratory complications. Horses should not be fed immediately before or after work to avoid digestive problems.

How long does it take for food to pass through a horse’s digestive system?
The passage of food through the small intestine typically takes three to six hours. However, the total transit time through the entire digestive system can vary depending on the type of feed and the individual horse.
Why is fiber important in a horse’s diet?
Fiber is essential for maintaining a healthy digestive system in horses. It provides bulk, stimulates gut motility, and supports the growth of beneficial bacteria in the hindgut.
What are some common digestive problems in horses?
Common digestive problems in horses include colic, laminitis, and ulcers. These issues can arise from various factors, including stress, diet, and management practices.
Understanding the length and function of a horse’s digestive tract is crucial for providing proper care and nutrition. A well-maintained digestive system contributes significantly to the overall health and well-being of these animals.
