Cud is the name given to the food of ruminants which is:
(a) swallowed and undigested.
(b) swallowed and partially digested.
(c) properly chewed and partially digested.
(d) properly chewed and completely digested.
Correct Answer: (b) swallowed and partially digested
Explanation:
The mixture of partially digested food and microorganisms returned to the mouth of ruminants from their stomach for further chewing is known as cud.
In animals like Termites, the cellulose is digested by microbes present in the gut or stomach.
In herbivores, there is a different compartment in the stomach for the digestion of cellulose which is known as rumen and the animals are called as ruminants.
The ingested food containing cellulose is stored in the rumen temporarily. The bacteria and enzymes present in the rumen conduct anaerobic bacterial digestion of cellulose.
Later the partially digested food is regurgitated to chew their cud.
