Detailed explanation-1: -Rumination is regurgitation of ingesta from the reticulum, followed by remastication and reswallowing. It provides for effective mechanical breakdown of roughage and thereby increases substrate surface area to fermentative microbes.

Detailed explanation-2: -The vomitus of ruminants contains rumen fluid and small feed particles. While regurgitation is a normal phenomenon in ruminants, abnormal regurgitation is usually the result of an oesophageal disorder, often affecting the intrathoracic part.

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).
