While foregut fermentation is generally considered more efficient, and monogastric animals cannot digest cellulose as efficiently as ruminants, [5] hindgut fermentation allows animals to consume small amounts of low-quality forage all day long and thus survive in conditions where ruminants might not be able to obtain nutrition adequate for their needs.
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.
Tannins can be toxic to ruminants, in that they precipitate proteins, making them unavailable for digestion, and they inhibit the absorption of nutrients by reducing the populations of proteolytic rumen bacteria. [36] [37] Very high levels of tannin intake can produce toxicity that can even cause death. [38]
Their population has declined by more than 60% in the last 20 to 25 years, and a 2018 study additionally revealed that although more than 360,000 gorillas inhabit the forests of Western Equatorial ...
Termites and protists have a symbiotic relationship (e.g. with the protozoan that allows the termites to digest the cellulose in their diet). For example, in one group of termites, a three-way symbiotic relationship exists; termites of the family Rhinotermitidae, cellulolytic protists of the genus Pseudotrichonympha in the guts of these ...
Since puppies drink their mother's milk, their bodies produce lactase, an enzyme that helps them digest the lactose sugars found in milk. Once they are weaned, however, they stop producing this ...
These findings indicate that factors such as excessive consumption of sugar-sweetened beverages or red meat as well as obesity, which contribute to an excess of energy, may be risk factors for the ...
Cellulose is a polymer made with repeated glucose units bonded together by beta-linkages. Humans and many animals lack an enzyme to break the beta-linkages, so they do not digest cellulose. Certain animals, such as termites can digest cellulose, because bacteria possessing the enzyme are present in their gut. Cellulose is insoluble in water.
