A calf is a newborn bovine or dairy animal. A heifer is a young female that has not yet had a calf and begun to milk. A cow is a mature female bovine or dairy animal and a bull is a mature male bovine or dairy animal. Cows give milk for about ten months (or about 305 days) after having a calf. They stop milk production during a two-month dry period before giving birth and entering another ten-month milk cycle.
