Estrus, or heat, is the period in which the doe will stand and allow the buck to breed her. This phase of the reproductive cycle may last between 12 to 36 hours. The period from one heat cycle to the next is referred to as the estrous cycle. In goats, the estrous cycle occurs every 18 to 24 days, or 21 days on average.
During breeding seasons your goats will need extra nutrition to support the stresses on their bodies. Heat, rut and pregnancy takes its toll on their bodies, so be sure to support them with extra grain, high quality hay and lots of forage. Your bucks in rut and your does will need about 1 lb of grain a day.
