Heifer. Heifer is the female cow who has passed the calf stage but has not reached the cow stage. Usually, the calf stage ends when the age reaches 10 months from birth. A female will be called a cow when she becomes a mother after reaching the reproductive viability. The heifer is the middle stage of the calf and cow.
After calving, it takes 60 to 90 days for cows to resume cycles. This period is called postpartum anestrous. In first calf heifers, postpartum anestrous lasts longer than mature cows. It normally takes 90 to 120 days for first calf heifers to resume cycles.
