A mare will usually enter estrus (heat) for the first time at around age 1. Mares are seasonally poly-estrus, which means they come into heat (or season) in the spring and cycle approximately every 21 days until the fall.
A healthy mare may continue to show signs of heat until the day she dies at 20 - 30 yrs of age. Most mares eventually will stop reproducing, but often continue to come into heat regularly.
There are seasons when it is common, but a lot of times they go in heat when they find an other male they want to foal with.

A mare goes into heat as part of her reproductive cycle. When a mare is in heat she can conceive a foal if she is bred. She cannot conceive if she is not in heat.
My mare goes into heat every 2 weeks, i think thats normal.
They can, but usually not. Horses will mostly only mate once the mare is in heat.
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.
Most mares will come into heat every 21 days. Usually 21 days after the day the mare first comes into heat, she will start into heat again, but some mares vary anywhere from 18 to 31 days in their heat cycles. Heat periods are generally longer earlier in the breeding season and many older mares have longer than average heat cycles. The period of time when the mare is fertile and can conceive a foal generally only occurs 24 to 48 hours before the mare goes out of 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.
There is no discharge that I know of but a mare in heat will usually urinate when a stallion is presented. When a stallion is present, other signs of a mare in heat are: turning the hindquarters to the stallion, raising the tail, squatting and a flexing or winking of the labia. When a mare is NOT in heat and a stallion is present, she is totally disinterested and will flatten her ears, squeal, kick and sometimes bite and kick at the stallion.
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.
This very much depends on the mare. Mares that are being used for performance are generally placed on progesterone based products to prevent them from cycling into heat during competition. The mare is allowed to enter heat between shows.
In heat or in estrus.
The first heat that occurs a few days after birth is called a Foal Heat. Breeding a mare on a foal heat is possible, but sometimes not the best thing for the mare. As a result many breeders do not breed on foal heat. Just because you can do something, doesn't mean you should.
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.
