Horses are non-ruminant herbivores of a type known as a "hind-gut fermentor." This means that horses have only one stomach, as do humans. However, unlike humans, they also have to digest plant fiber (largely cellulose) that comes from grass and hay. Therefore, unlike ruminants, who digest fiber in plant matter by use of a multi-chambered stomach, horses use microbial fermentation in a part of the digestive system known as the cecum (or caecum) to break down cellulose.
