Question

Cud chewing animal is
A) Cow
B) Horse
C) Pig
D) Rhinoceros

Answer 1

Hint: They are the large quadrupedal mammals having cloven hooves. Their digestive system is highly specialized and allows them to digest poor plants as food. They have four-chambered stomachs. They are known for rechewing their food.

Complete Answer:
- Cud chewing animals are cows. These cattle are best known for the regurgitation and rechewing the food which is called as cud chewing. When the animal is feeding, they swallow without being chewed and directly went to the rumen for storage.
- Then, animals find a quiet place to continue the process of digestion and food which is swallowed back up into the mouth again where food is now called cud. This is chewed by the molars and grinding down the coarse vegetation to small particles.
- The cud is again swallowed and further digested by microorganisms in the rumen. Cows generally spend 5 to 8 hours chewing their cud.
- These microorganisms are responsible for decomposing cellulose into the fatty acids. This is used as the primary metabolic fuel. These microbes also help in synthesizing nitrogenous sources like ammonia and urea.

Thus, the correct answer is option A i.e., Cow.

Note: Cow, deer, sheep, goats and antelope are the examples of the animals that are called cud chewing animals. During the digestive process, cud is produced and this process is called rumination. The four chambers of the stomach in the cow include rumen, reticulum, omasum, and abomasum. The rumen is the largest and the reticulum is the smallest chamber. The abomasum is also called “true stomach”.
