Detailed explanation-1: -Organisms like cows and buffaloes swallow food fast and store it in their stomach. Later on, they bring this food (cud) back to their mouth and chew it again. This process of chewing cud is called rumination and these animals are called ruminants.

Detailed explanation-2: -What is rumination? Rumination or cud-chewing is the process by which the cow regurgitates previously consumed feed and chews it further. The larger particles in the rumen are sorted by the reticulorumen and reprocessed in the mouth to decrease particle size which in turn increases the surface area of the feed.

Detailed explanation-3: -Rumination is the process where animals rechew cud to breakdown plant matter further and to stimulate digestion. Such animals are called ruminants and they have a specialized digestive system to help them breakdown tough, fibrous plant matter.

Detailed explanation-4: -Rumination is a complex process involving regurgitation, remastication, insalivation, and deglutition.

Detailed explanation-5: -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.
