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).
During this time, the mare will have an estrous cycle of 21 days (Â±3 days). The estrous cycle is composed of two phases: the estrous phase (in heat) and the diestrous phase (out of heat). Estrus usually lasts for 6 days, but can be 4-10 days, depending on the mare.
