Digestive system of ruminants [ edit ] Hofmann and Stewart divided ruminants into three major categories based on their feed type and feeding habits: concentrate selectors, intermediate types, and grass/roughage eaters, with the assumption that feeding habits in ruminants cause morphological differences in their digestive systems, including ...
The ruminant digestive system. The omasum, also known as the bible, [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 ...
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.
The ruminant digestive system. 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.
Hindgut fermentation is a digestive process seen in monogastric herbivores (animals with a simple, single-chambered stomach). Cellulose is digested with the aid of symbiotic microbes including bacteria, archaea, and eukaryotes. [1] The microbial fermentation occurs in the digestive organs that follow the small intestine: the cecum and large ...
Foregut fermentation is a form of digestion that occurs in the foregut of some animals such as the hamster rat, langur monkey, and the hippopotamus. [1] It has evolved independently in several groups of mammals, and also in the hoatzin, a bird species.
Enteric fermentation was the second largest anthropogenic source of methane emissions in the United States from 2000 through 2009. [7] In 2007, methane emissions from enteric fermentation were 2.3% of net greenhouse gases produced in the United States at 139 teragrams of carbon dioxide equivalents (Tg CO 2) out of a total net emission of 6087.5 Tg CO 2.

Cud is a portion of food that returns from a ruminant's stomach to the mouth to be chewed for the second time. More precisely, it is a bolus of semi-degraded food regurgitated from the reticulorumen of a ruminant. Cud is produced during the physical digestive process of rumination. [1]
