Estrus is defined as the period where a female (in this case, a cow or heifer) is receptive to a male (or, the bull). Estrous, on the other hand, is the whole reproductive heat cycle that a female goes through, from heat period to no heat period (Proestrus, Estrus, Metestrus, and Diestrus).
Stages of the Estrus Cycle. The heat cycle consists of four stages. They are proestrus, estrus, metestrus or diestrus, and anestrus. Vaginal discharge and male dogs being attracted to the females characterize proestrus, lasting between four and twenty days, but they will not be willing to mate at this time.
