The digestive system of a horse works very differently from that of a human. Food passes quickly through a relatively small stomach designed to take in frequent meals throughout the course of the day. In the small intestine, enzymes digest starch, protein and fat.
Horses cannot vomit and are therefore more prone to digestive disruptions, such as choke and colic, than other animals.
