The rumen, also known as a paunch, is the largest stomach compartment in ruminants. [ 1 ] The rumen and the reticulum make up the reticulorumen in ruminant animals. [ 2 ] The diverse microbial communities in the rumen allows it to serve as the primary site for microbial fermentation of ingested feed, which is often fiber-rich roughage typically ...

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.

The reticulum lies against the diaphragm and is joined to the rumen by a fold of tissue. The rumen, far and away the largest of the forestomaches, is itself sacculated by muscular pillars into what are called the dorsal, ventral, caudodorsal and caudoventral sacs.

…stomach of the cow, the rumen, is a fermentation chamber in which bacteria digest the cellulose in grasses and feeds, converting them to fatty acids and amino acids, which are the fundamental nutrients used by the cow and the basis for the cow’s production of milk.

The rumen is the largest (by volume) compartment of the ruminant forestomach. The primary function of the rumen is as a storage compartment to facilitate microbial (bacterial and protozoal) fermentation of ingesta.

2022年11月2日 · The rumen is the first chamber of the ruminant stomach. It is the largest chamber and has regular contractions to move food around for digestion, eliminate gases through eructation and send food particles back to the mouth for remastication.

2024年11月23日 · Ruminants are mammals that digest plant based food by processing it in a series of chambers in their stomachs. There are about 150 species of ruminants, including both domestic and wild species. Ruminating mammals include cattle, goats, sheep, giraffes, bison, moose, elk, yaks, water buffalo, deer, camels, alpacas, llamas, and antelope.
