Observe your surroundings (a)How does the cow eat grass

Answer»

When a cow first takes a bite of grass, it is chewed very little before it is swallowed. ... This process of SWALLOWING, “un-swallowing”, re-chewing, and re-swallowing is called “rumination,” or more commonly, “chewing the CUD.” Rumination enables cows to chew grass more completely, which IMPROVES digestion.
