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 indigestible by mammalian digestive systems.
Rumen fermentation produces large amounts of organic acids, thus maintaining the appropriate pH of rumen fluids is a critical factor in rumen fermentation. After digesta passes through the rumen, the omasum absorbs excess fluid so that digestive enzymes and acid in the abomasum are not diluted.
The omasum, also known as the green, [1] the fardel, [1] the manyplies [1] and the psalterium, [1] is the third compartment of the stomach in ruminants. The omasum comes after the rumen and reticulum and before the abomasum. Different ruminants have different omasum structures and function based on the food that they eat and how they developed ...
Tripe refers to cow (beef) stomach, but includes stomach of any ruminant including cattle, sheep, deer, antelope, goat, ox, giraffes, and their relatives. Tripas, the related Spanish word, refers to culinary dishes produced from the small intestines of an animal. In some cases, other names have been applied to the tripe of other animals.
Anatomically it is the smaller portion of the reticulorumen along with the rumen. Together these two compartments make up 84% of the volume of the total stomach. The reticulum is colloquially referred to as the honeycomb, bonnet', [1] or kings-hood. [1] When cleaned and used for food, it is called "tripe".
The abomasum, also known as the maw, [1] rennet-bag, [1] or reed tripe, [1] is the fourth and final stomach compartment in ruminants. It secretes rennet, which is used in cheese creation. The word abomasum (ab-"away from" + omasum "intestine of an ox") is from Neo-Latin and it was first used in English in 1706. It is possibly from the Gaulish ...
Being ruminants, the stomach is composed of four chambers: the rumen (80%), the omasum, the reticulum, and the abomasum. The ciliates and bacteria of the rumen ferment the complex cellulose into simpler fatty acids , which are then absorbed through the rumen wall.
A cannula in a cow's side. A cannulated cow or fistulated cow refers to a cow that has been surgically fitted with a cannula. [1] A cannula acts as a porthole-like device that allows access to the rumen of a cow, to perform research and analysis of the digestive system and to allow veterinarians to transplant rumen contents from one cow to another.
