HUMAN NUTRITION

Detailed explanation-1: -Abnormal regurgitation in ruminants is defined as the discharge of food from the mouth [1] and occasionally from the nose [2] immediately after prehension of feed and before the feed enters the forestomachs.

Detailed explanation-2: -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.

Detailed explanation-3: -Rumination syndrome (also known as rumination disorder or merycism) is a feeding and eating disorder in which undigested food comes back up from a person’s stomach into his or her mouth (regurgitation).

Detailed explanation-4: -In the reticulum, the food also mixes with saliva to produce small wads of food called cud. Cows regurgitate these bits of cud back into their mouths, where they then chew them completely. Chewing cud releases saliva which acts as an antacid in the rumen, allowing cows to digest their food better.

Detailed explanation-5: -Proper buffering of the rumen allows a cow to digest forages better and to eat more feed which helps her produce more milk. What stimulates a cow to chew her cud? When a cow chews her cud, she is regurgitating a bolus of food into her mouth which she rechews and reswallows.
