Stomach of Ruminants
- In ruminants like cattle, sheep and deer etc. the stomach is structurally very complicated.
- It has four specialised chambers called rumen, reticulum, omasum and the abomasum and hence the stomach is 'Compound Stomach'
- Process of digestion is as follows :
- The process begins in the first two chambers (rumen and reticulum)
- Rumen produces cellulase enzyme that digests plant fibres
- The digested part is further sent to third chamber 'the omasum'
- In the omasum, the bacterial action takes place that results in formation of 'Cud'
- This cud produced is regurgitated back into the animal’s mouth where they can be chewed again. The saliva of the cow greatly aids in digesting the cud
- This then passes into the omasum again and then into abomasum
- The abomasum is regarded as 'true stomach' where final digestion takes place and the food then enters the intestine
