What is a non ruminant stomach?
Non-ruminant animals are animals with a single-compartment stomach, such as swine, poultry, horses, dogs, cats, and humans. Non-ruminant nutrition looks at the diet of these animals as it relates to their digestion, growth, performance, and overall health.
What is a four chambered stomach?
The ruminant stomach is a multi-chambered organ found in ruminants (see picture at right). It is usually composed of four separate chambers and allows digestion of large quantities of plant matter that would be relatively indigestible for most other types of mammals, in particular grass and the leaves.

It is the so called “true stomach” since this compartment has mostly the same function as the stomach in monogastric animals, such as pigs and humans. In fact, it is in the abomasum that the cow’s own stomach acids and enzymes are used to further breakdown ingested feed before it passes into the small intestine.
What does abomasum look like?
The abomasum is the ruminant’s true or glandular stomach. Histologically, it is very similar to the stomach of monogastrics. The interior of the rumen, reticulum and omasum is covered exclusively with stratified squamous epithelium similar to what is observed in the esophagus.
