ruminant Animals such as the cow, sheep, and goat, which possess four stomachs, as distinct from monogastric animals, such as man, pig, dog, and rat. 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.
