Ruminants and Monogastrics
Ruminants are those animals that have a multiple-chambered stomach designed to digest herbaceous matter such as grass by the process of fermentation. Monogastrics are those animals that have a single-stomach that is designed for digestion of animal protein and highly-digestible phyto-nutrients such as fruits and grains. Questions about ruminants and monogastrics, including those about psuedo-ruminants (animals that have a single stomach like a monogastric but have their main fermentation vat in the cecum), can be asked and answered here.

Why is abomasum called a true stomach?
Because it functions like a true stomach, secreting hydrochloric acid and peptidases to digest proteins and break down digesta that the rumen couldn't break down. The abomasum is actually the stomach that newborn calves have better developed than the other three chambers of a bovines' stomach, enabling easier passage to digest milk from its mother.
How does acidosis lead to rumen atony?
Acidosis in ruminants, often caused by a rapid intake of high-concentrate diets, leads to a decrease in rumen pH, disrupting the normal microbial ecosystem. This imbalance results in reduced fiber digestion and motility, causing rumen atony, which is characterized by a lack of muscle tone and contractions in the rumen. The decreased movement hampers the mixing and passage of feed, exacerbating the acidosis and creating a vicious cycle that can lead to further digestive issues. Ultimately, the overall health and productivity of the animal are compromised.
Cattle, sheep, goats, and deer are animals that ruminate in order to fully digest feedstuffs.
The carpet weavers written by carol rumens?
the children are at the loom of another world Their braids are oiled and black, their dresses bright Their assorted heights would make a melodious chime They watch their flickering knots like television as the garden of Islam grows, the bench will be raised Then they will lace the dark-rose veins of the tree-tops The carpet will travel in the merchant's truck It will be spread bye the servants of the mosque Deep and soft, it will give when heaped with prayer. The children are hard at work in the school of days From their fingers the colours of all-that-will-be fly and freeze into the frame of all-that-was.
Why are sheep called ruminants?
They are called ruminants because they have a four chambered stomach (Rumen, Abomasum, reticulum, omasum), food will enter the rumen and then the animal will then (during its resting period) regurgitate the food re chewing it and then swallowing it where it then enters the remaining three stomachs (this process is called chewing cud and is repeated until all food is digested).
If you are talking about cow's milk, then I suppose yes it is in a very roundabout way.
First of all understand that milk is made by the mother animal out of her own body tissues. Milk is a modified form of "sweat" produced by modified sweat glands.
However to produce milk the mother animal has to eat food, in the case of human milk the mother just eats more human food and drinks water and the body turn this into the raw material needed to produce the rich breast milk needed to feed her baby.
With cows, although they eat grass, they can not digest this grass because it is made of "cellulose". They have special stomachs in which the chewed up grass is fermented by bacteria that live naturally in these stomachs and the bacteria break down and grow on the cellulose. The cow then "digests" these bacteria as its food.
Thus in the case of ruminants, the food the mother cow lives on is bacteria and thus the milk was indeed originally bacteria.
When does a beef calf have a functional rumen?
A calf's rumen starts growing after the calf is born, and often has a fully functional rumen by the time he's around 3 months of age. By this time, he's about as dependent on his dam's milk supply as he is on the forage that his dam is or has taught him to eat. Milk production (as a way of weaning him) decreases by the time he's 3 months of age, and by the time he gets weaned, which is around 6 to 10 months of age, milk is in low supply and he's eating more forage than suckling from his dam.

No. Horses are hind-gut fermentors. They have a monogastric (single-chambered stomach), but a very large cecum where the small intestine joins onto the large intestine. This is where most of the fermentation takes place.
