One-third of a cow's gestation period is called what?

First Trimester

Trimester

Gestation is divided into three equal parts called trimesters. Each trimester covers about one-third of the total gestation length. For cows, gestation is roughly nine months, so each trimester is about three months. The general term for that one-third is a trimester, while the specific ones are the first, second, or third trimester.
