Hello Student,

The ruminant stomach is mainly divided in four parts , which are :

1. Rumen : Largest part of stomach for churning of food with the help of cornified surface of villi . It also has symbiotic microorganisms which help in fementation of cellulose.
2. Reticulum : It is lined by keratinised epithelium
3. Omasum : Helps in mechanical churning and grinding of food Also helps in absorption of fluid and electrolytes.
4. Abomasum : Secretes gastric juice and shows chemical digestion. it is considered as true stomach of ruminants.

Note : Omasum is absent in camel .

Rumen and reticulum have diverticula or water pockets for temporary food storage.

Hey

Ruminant stomachs have four compartments or parts which are listed below : -

• rumen ,
• the reticulum,
• the omasum and
• the abomasum.

Rumen microbes ferment feed and produce volatile fatty acids, which is the cow's main energy source.
Rumen microbes also produce B vitamins, vitamin K and amino acids.


Thank you
