A cow’s stomach has four parts. It must chew its food twice before the food can be digested.
Cattle have the habit of swallowing their food and later bringing it back to the mouth to be rechewed. Hence they are called “ cud-chewing” animals.
The cow has an end way of digesting its food. A cow’s stomach is divided into four compartments. Each compartment helps digest the food the cow eats.
While a cow is grazing it chews its food only slightly. When the food is first, swallowed, it goes into the first compartment of the stomach where it is moistened.
From there it passes into the second compartment. Have the food forms into a soft ball called a cud. Later, when the cow is resting, the cud moves back up in the cow’s mouth to be chewed thoroughly.
This time, when the food is swallowed, it passes into the third and fourth compartments when real digestion takes place.
Animals that chew cuds and have this kind of stomach are called ruminants. Ox, deer sheep, goats and antelope are ruminants. – Dick Rogers
