ruminant animals; ruminants Animals having a rumen - a large digestive vat in which fibrous plant material is partially broken down by microbial fermentation, prior to digestion in a "true" stomach (the abomasum). There are also two other stomachs - the reticulum and the omasum. Typical ruminants are cattle and sheep. monogastric animals Animals with simple stomachs that do not ruminate. cf ruminant animals. Digestive system of a horse: Horses are herbivores with a digestive system adapted to a forage diet of grasses and other plant material, consumed steadily throughout the day. Therefore, compared to humans, they have a relatively small stomach but very long intestines to facilitate a steady flow of nutrients. A 1,000 pounds (450 kg) horse will eat 15 to 25 pounds (6.8 to 11 kg) of food per day and, under normal use, drink 10 US gallons (38 L) to 12 US gallons (45 L) of water. Horses are not ruminants,

Unformatted text preview: so they have only one stomach, like humans, but unlike humans, they can also digest cellulose from grasses due to the presence of a "hind gut" called the cecum, or "water gut," which food goes through before reaching the large intestine. Unlike humans, horses cannot vomit, so digestion problems can quickly cause colic, a leading cause of death. The cow's: Possess four stomachs, as distinct from monogastric animals, such as men. The four are: the rumen, or first stomach, where bacterial fermentation produces volatile fatty acids, and whence the food is returned to the mouth for further mastication (chewing the cud); the reticulum, where further bacterial fermentation produces volatile fatty acids; the omasum; and the abomasum or true stomach. The bacterial fermentation allows ruminants to obtain nourishment from grass and hay which cannot be digested by monogastric animals....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
