Question

10. Why are cows always seen chewing even where
they are resting?​

Answer 1

Answer:

The reason is that cows must chew their food twice in order to digest it properly. Cows spend nearly eight hours out of every day chewing their cud. This plus normal chewing of food can total upwards of 40,000 jaw movements per day. When a cow first takes a bite, it chews just enough to moisten the food.

Answer 2

....When cows chew their cuds they secrete saliva. ... This saliva contains a natural antacid which helps to buffer the rumen or first compartment of the stomach. Proper buffering of the rumen allows a cow to digest forages better and to eat more feed which helps her produce more milk.......
