There are dozens of different conditions that can cause a horse to show signs of abdominal pain. Most (but not all) involve the digestive system, most often the stomach or intestines. Therefore, it stands to good reason that understanding the anatomy of your horse’s digestive system can help you become a better steward for your equine friend.
Fun fact: many people associate digestive health with stomach health. But did you know that the horse has the smallest stomach in relation to body size of all domestic animals? The stomach of the horse is also the smallest unit of the digestive tract, comprising less than 10% of the total volume of the horse’s digestive tract. By contrast, the hindgut is huge and plays a significant role in the horse’s digestive process by serving as the home of friendly bacteria that ferment fiber and turn it into energy.
Hindgut problems can produce obvious physical signs like loss of weight, poor condition, poor performance, diarrhea and colic. Some symptoms however can be less obvious, like poor temperament and training issues.
The key to ensuring good digestive health is good management practices that include (but are not limited to) establishing a set daily routine; feeding a high-quality diet comprised primarily of high-quality roughage; avoid overloading the digestive tract with concentrate rations; providing clean, fresh water at all times; establishing a regular turnout and exercise routine; setting up a regular deworming and dental care program with your veterinarian; reducing stress and making any changes (to diet, housing and exercise) gradually.
Consult your veterinarian about how to maximize your horse’s digestive health. A healthy horse is a happy horse!
