Ovarian cycle in cow and buffalo is

Solution(By Examveda Team)

Ovarian cycle in cows and buffalo is 21 days.
The ovarian cycle controls the production and release of eggs and the cyclic release of estrogen and progesterone.
The ovarian cycle of the cow is generally about 21 days long, but it can range from 17 to 24 days in duration. Each cycle consists of a long luteal phase (days 1 - 17) where the cycle is under the influence of progesterone and a shorter follicular phase (days 18 - 21) where the cycle is under the influence of estrogen. The estrous cycle in cattle is complex and regulated by several hormones and organs.
