Question

How they calculate the cow or Buffalo age by seeing the teeths of the animals?

Answer 1

Do you mean by sawing in the teeth or looking inside of a live animal?

A tooth has rings on it- the number of rings is your age.

In a live animal, they look at what teeth are there (are more teeth still coming in?) and the wear of the teeth. Teeth wear down at a semi-predictable rate, and by a certain age, the teeth are worn down to the gums.
