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.
Heat or estrus is defined as the time at which a mare is receptive to a stallion, allowing for mating. The heat, or estrus, phase is one of two phases that make up the estrous cycle of the mare. The estrous cycle is defined as the interval from the beginning of one heat period to the beginning of the next heat period. Do not force a stallion to breed a mare to which he has considerable objection. 2  Do not use the stallion excessively as a teaser. 3  The most common practice on large breeding farms is to have a stallion that is used solely as a teasing horse.
