• Cow's and some grass-eating animals can swallow large amounts of food at a time and later brings back the swallowed food into the mouth to chew it again. This process of chewing the cud is called rumination and such animals are called ruminants.
• Grass is rich in cellulose, a carbohydrate, which many other animals and humans cannot digest, but can be digested by ruminants.

☞Process of nutrition in ruminants:-

★Ingestion★

• The animals take in food such as grass into the mouth, chew it and mix it with saliva. They have big chewing teeth with powerful jaw muscles to chew the grass again and again. The chewed food passes through the oesophagus into the stomach.

★Digestion★

• Digestion of chewed food takes place in stomach. The stomach of ruminants is four chambered..

1. Rumen
2. Reticulum
3. Omasum
4. Abomasum

➭Explanation of the four chambers:-

☆Rumen☆

• It is the first and largest chamber, which stores large quantities of food that is quickly consumed. The food is partially digested here. It is called cud. Cellulose is digested in the rumen by billions of bacteria present there.

☆Reticulum☆

• It is the second chamber into which food enters from the rumen. Here, the contents of both rumen and reticulum mix freely. The cud is brought back to the mouth and is re-chewed and re-swallowed.

☆Omasum☆

• It is the third and the smallest chamber of the stomach into which food passes after chewing. Excess of water is absorbed from the food here.

☆Abomasum☆

• It is the last chamber of the stomach into which food from the omasum passes. The walls of the abomasum secrete digestive juices that helps in digestion.

★Absorption★

• The process of absorption begins in the stomach itself, the main absorptive organ is intestine. The small intestine receives secretions from the pancreas and liver and digestion of food ends here. Villi present in the small intestine increases the surface area for absorption.
• Water from the undigested food is absorbed in the large intestine. The undigested food excreted our as faeces(egestion)

☞some word meaning;

1. Cud=food of a ruminant regurgitated to be chewed again is called as cud.
2. Nucleus=the Central part of some cells containing genetic material.

What is nutrition in ruminants???

$\text{AnSwEr!}$

Ruminants are mammals that are able to acquire nutrients from plant-based food by fermenting it in a specialized stomach prior to digestion, principally through microbial actions. ... The process of rechewing the cud to further break down plant matter and stimulate digestion is called rumination.
