Not much. For show mares that get cranky the vet can try to control it with hormones. But that is a drastic move and is not that common. There is also spaying the mare but that is even more drastic. I know of a person that had a beautiful mare that was impossible to show because of her heat cycles. She opted for spaying the mare and it made little difference. There are many people that will not ride a mare for this reason. I have mares and I can't imagine not have them. They can be difficult but their personalities are so much fun.

Do mares still go into estrus when infertile?

If the mare is infertile because of age, yes they will continue to go into estrus. The hormones still work, but no more eggs are being released. If the mare has been spayed (which is very rare) and the ovaries are removed, the mare will no longer go into estrus.


What do you call a mare that is ready to breed?

In heat or in estrus.


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.


What can I give my mare to keep her out of heat this summer?

Stopping female horse estrus?

Once a mare is in estrus she has to be allowed to go out before methods can be employed to avoid any additional heat cycles. Anestrus can be maintained through the use of progesterone in oil injected IM or through the use of progesterone products on a daily basis. Ideally, these products are used to prevent mares from cycling into heat during an important event where estrus would detract from the mare's performance, and then discontinued once the event ends. These products, if used continously for a prolonged period can result in intrauterine infection. Another method involves depositing a sterile sphere into the mare's uterus, which "fools" the mare's reproductive system into a false pregnancy. The use of this method has some advantages over the progesterone


Do mares heat cycle behavior reduce with age?

Mares with normal estrus behavior will cycle the same way most of their lives. There are disease processes or reproductive anomalies that can develop that will cause a mare to stop cycling or change cycling behavior but the conditions are somewhat rare and can occur at any age.


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.


Want to terminate mare's pregnancy. Am told she can absorb her foal. How does this happen?

If the mare has been pregnant for less than 35 days the pregnancy can be terminated with the use of a single dose of prostiglandin. Essentially, this will disrupt the corpus luteum (primary producer of progesterone which maintains early pregnancy) and the mare will return to estrus in 5 to 7 days. The conceptus will pass out through the cervix during the heat cycle. If the mare is 35 plus days in foal multiple doses of prostin will be required and often these mares do not return to estrus due to the formation of endometrial cups even if the conceptus is aborted. Aborting a mare farther along in her pregnancy is more problematic but can still be done.
