Heifer vs Cow. It is a widely known fact that cow is the female cattle or the referred term for the female of many other animals including elephants and whales. However, only a very small portion of the people would have heard about heifer.
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.
