what is the process of rumination?
Answers
Answer:
Rumination, also called cud-chewing, is the process by which the cow regurgitates (casts up) previously consumed feed and masticates it a second time. The re-chewed feed with saliva is formed into a bolus and swallowed a second time. It is the floating, large particles on top of the rumen which are re-chewed.

Rumination is a specialized digestion process found in most hoofed mammals with an even number of toes-such as cattle, sheep, goats, deer, antelope, camels, buffalo, giraffes, and chevrotains. All of these plant-eating animals lack the enzyme cellulase, which is capable of breaking down the tough cellulose in plant cell walls. The stomach of these grazing herbivores consists of four chambers—the rumen, the reticulum, the omasum, and the abomasum—each playing different roles in the digestion process. The ruminant animal swallows its food rapidly without chewing, and later regurgitates it (brings it back up into the mouth), then masticates it (chews), and finally re-swallows it.
