The ideal Renaissance man. An aspect of court life was the idea that the ideal Renaissance man should be widely accomplished. This is reflected in Measure for Measure when, the Duke describes himself as âa scholar, a statesman and a soldier'. The courtier's, soldier's, scholars' eye, tongue, sword!
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).
The estrous cycle is divided into two periods, estrus and diestrus with estrus being the time when the mare is in heat, usually for 3 to 7 days. During diestrus, typically 14 to 18 days, the mare is unreceptive to a stallion. Ovulation occurs one to two days before the end of estrus.
