When a domesticated mare foals, she nurses the foal for at least four to six months before it is weaned, though mares in the wild may allow a foal to nurse for up to a year. The estrous cycle, also known as season or heat of a mare occurs roughly every 19â22 days and occurs from early spring into autumn. As the days shorten, most mares enter an anestrus period during the winter and thus do not cycle in this period.
A mare will go into her heat cycle around once every 20-23 days during the breeding season and a standing heat or period when she is ready to breed every 3-8 days.A mare is in anestrous (time when your mare's cycle is inactive) during the winter.nd horses only cycle in the spring, summer and early fall. Most mares shut down in the winter. It seems like mares are in heat all the time, because if their heat cycle lasts 5 days, and they ovulate right before going out of heat, then they are starting the whole process again just 14 to 17 days later!
