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.
Tips. 1  Check all of your heifers and cows, no matter how certain you are that a particular female is pregnant or not. All cows and heifers need to be checked in one or two days, depending on the size of the herd and the method used. 2  Know your limitations and the limitations of each method of each pregnancy exam.
