How does digestion take place in ruminants ?

Ruminant Digestion. Like other vertebrates, ruminant are unable to digest plant material directly, because they lack enzymes to break down cellulose in the cell walls. Digestion in ruminants occurs sequentially in a four-chambered stomach.

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 typically requires the fermented ingesta (known as cud) to be regurgitated and chewed again.

RUMINANT DIGESTION INCLUDES THE INVOLVEMENT OF FOUR CHAMBERS OF STOMACH. THEY ARE -  RUMEN, RETICULUM, OMASUM , ABOMASUM. THE FOOD IS PARTIALLY CHEWED AND STORED IN RUMEN. LATER THEY TAKE IT OUT AND CHEW THE CUD. THEN THE FOOD DIRECTLY GETS INTO THE  RETICULUM. FROM THERE IT DIGESTS AND GOES TO THE OMASUM. FROM OMASUM IT AGAIN GOES TO THE RUMEN .THERE SOME DIGESTION TAKES PLACE AND THEN THE FOOD GOES BACK TO THE OMASUM BUT THROUGH THE RETICULUM. THEN IT GOES TO THE ABOMASUM . IN ABOMASUM DIGESTION LIKE HUMANS TAKES PLACE .
