At first glance, the equine digestive system looks similar to that of other animals, including humans. Horses have all the same major structures, such as the mouth, esophagus, stomach, and small and large intestines. As you will see, however, important differences in structure and function of most elements of the gastrointestinal tract exist between humans and horses, the major ones being the cecum and large intestine. Because horses are herbivorous, nonruminant hindgut fermenters, their cecum and large intestine are far more voluminous and intricate, playing a much more prominent and integral role in processing feeds compared to a human’s large intestine.
