The large fermentation pouch of the ruminant animal in which bacteria and protozoa break down fibrous plant material that is swallowed by the animal; sometimes referred to as the paunch.

The forestomach of ruminant animals in which cellulose digestion occurs.

The first of the four compartments of the stomach of a cow or sheep. The rumen is a large chamber that serves as a fermentation vat for microbial digestion of feedstuffs

The largest of the ruminant forestomachs.

The first stomach division in animals known as ruminant that chew cud, such as cows and goats. Rumen is also the term for the first stomach division in whales and in dolphins.

A compartment of the ruminant stomach that is similar to a large fermentation pouch where bacteria and protozoa break down fibrous plant material swallowed by the animal. Sometimes referred to as the paunch.

The large first compartment of a ruminant's stomach containing microbial population that is capable of breaking down forages and roughages.

the part of the sheep's stomach where bacteria, yeast, fungi and protozoans breakdown the feed through fermentation. It has a 5-10 gallon capacity. Keeping the inhabitants of the rumen happy and healthy is a key part of the shepherd's job

The first stomach in the digestive system of a ruminant animal. Most food collects here immediately after being swallowed. It is later returned to the mouth as cud for thorough chewing.

(rew´ mun) • The first division of the ruminant stomach. It stores and initiates bacterial fermentation of food. Food is regurgitated from the rumen for further chewing.

The first division of the stomach of a ruminant animal, in which food is partly digested before being regurgitated for further chewing.

the first large compartment of the stomach of a bovine; its bacteria and protazoa break down cellulose

The fermentation vat of a ruminant's stomachs.

The large first compartment of the stomach of certain animals in which cellulose is broken down by the action of bacteria.

the part of a ruminant's stomach within which vegetable matter is fermented

The rumen is the first chamber of the four part stomach. It is also the main digestive chamber, containing billions of microorganisms designed to break down food into materials usable by the digestive system.

The rumen, also known as the fardingbag or paunch forms the larger part of the reticulorumen, which is the first chamber in the alimentary canal of ruminant animals. It serves as the primary site for microbial fermentation of ingested feed. The smaller part of the reticulorumen is the reticulum, which is fully continuous with the rumen, but differs to it with regard to the texture of its lining.
