Cow Chewing

Chewing a cud is the way a cow digests its food thoroughly.  A cow has a special stomach with a storage section called a “rumen.”  When the cow eats some grass, she chews it just enough to moisten it.  The food collects in the rumen, where it is softened and formed into a ball called a “cud.”

Later, when the cow is resting, the cud moves back up into the cow’s mouth for careful chewing.  After that, the food is swallowed into other parts of its stomach for more complete digestion.  Camels, deer, goats and sheep are other cud-chewing animal.– Dick Rogers
