Describe The Process Of Digestion In Ruminants Class 7

All plant-eating mammals or herbivores, such as castles, antelopes, giraffes, sheep, goat, giraffes, deer, camel and gazelles, are called ruminants.

Ruminants refer to rechewing the cud to break down plant matter further and stimulate digestion is called rumination. The process of digestion in ruminants is quite different compared to other animals.

They have different dentition.

  • They lack canines in both the jaws
  • Incisors are present only on the upper jaw
  • They have a very strong molar, which helps in chewing the cud.

The stomach is divided into four chambers– the rumen, reticulum, omasum and abomasum, among which the rumen is the largest part of the stomach.

The Process Of Digestion In Ruminants

Ruminants or plant-eating mammals swallow the food quickly and store it in the rumen-the largest part of the stomach.

Once the rumen is full, the food is moved into the second part of the stomach, the reticulum.

The presence of the digestive juices in the reticulum partially digest the food.

The partially digested food in the reticulum is called cud.

When these mammals are resting, they bring back the cud into the mouth for regurgitation.

Now, the cud is chewed thoroughly and swallowed into the omasum for further digestion.

Later the cud is moved into the abomasum for digestion brought by digestive juices.

The complete digestion of cellulose is brought by the symbiotic bacteria present in the caecum. Caecum, a large sac-like structure present between the small and large intestines.

The Process Of Digestion In Ruminants is completed in the intestine.
