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.
Cows may produce their first calf when they are two, and most produce a calf by age 3. Each May, cows give birth to 1 to 2 calves. Cows rarely have more than 2 calves and young cows rarely have twins. A cow's nutritional condition (body weight) determines the number of calves born and when a cow first breeds.
