Detailed explanation-1: -The rumen (on the left side of the animal) is the largest stomach compartment and consists of several sacs. It can hold 25 gallons or more of material depending on the size of the cow. Because of its size, the rumen acts as a storage or holding vat for feed.

Detailed explanation-2: -The rumen is the largest stomach compartment, holding up to 40 gallons in a mature cow. The reticulum holds approximately 5 gallons in the mature cow. Typically, the rumen and reticulum are considered one organ because they have similar functions and are separated only by a small muscular fold of tissue.

Detailed explanation-3: -Rumens are the sac-like structure in the ruminants which helps in the digestion of cellulose present in the food. The ruminants digest the food partially in the mouth and stores it into rumen for digestion of cellulose present in the food. The partially digested food is known as cud.

Detailed explanation-4: -Goats belong to the small ruminant group of animals and have no upper incisor or canine teeth but a dental pad instead. The rumen is the largest part of four stomach compartments with the capacity of roughly 2-6 pounds.
