A mare goes into heat, or estrus, as part of her reproductive cycle to attract a mate and potentially conceive a foal. During this time, her hormones fluctuate, causing changes in behavior and physical signs like increased vocalization, swelling of the vulva, and increased interest in mating.

How do you know when a horse is in heat and what are the signs?

A mare may become more tempermental when she is in heat, and possibly more agressive. Another characteristic that a mare is in heat is what is called flagging or winking. A mare may lift her tail in front of a male horse to get his attention. The most sure sign that a mare is in heat is her acceptance of being near a stallion. If a mare is in heat around a stallion she may squat and urinate showing she is ready to breed.


How would you trick a mare to go into heat?

You can manipulate a mare's estrus (heat) cycle several ways. Put the mare under lights early in the winter to fool her body into thinking it's spring a few weeks earlier. Give the mare a shot of Lutalyse. This chemical makes the mare cycle sooner than normal - usually about 3-5 days after the injection. Tease the mare. A mare that doesn't have normal cycles can sometimes be encouraged to come into estrus sooner with exposure to a stallion.

How many time a year does a mare go into heat?

Mares are notorious for having inconsistant heat cycles, especially young fillies and a mare over the age of 15. TYPICALLY, a mare is in heat for 4 to 8 days, depending on the time of year and whether or not a stallion is present (so IN heat about a week on average) and OUT of heat for 14 to 16 days (about 2 weeks on average) In the late winter or early spring, a mare may be in heat the full 8 days while in mid-summer through winter only about 4 days, so how many times per year she is in heat can vary greatly.


Can a mare who isn't in heat get pregnant?

yes they can, a mare, when introduced to a stud can, within minutes be in a standing heat. Answer2: Mares can only get pregnant while in heat (Estrus), however some may not show signs that they are in Estrus, leading owners to believe the mare is not receptive or able to become pregnant. If a mare does not become pregnant she will cycle again until either she becomes pregnant or the daylight hours shorten which helps to stop the heat cycle in horses. Ovulation in mares typically begins in March and ends in October, though it can go for longer or shorter depending on your location.
