How long does a mares heat cycle last?
Mares are seasonal breeders that cycle from about early May through October. A normal cycle consists of roughly seven days of estrus and a 14-day period of diestrus (when she is not in heat).
What is Marish behavior?
A mare’s reproductive cycle is controlled by her hormones, which in turn are influenced by exposure to sunlight. So-called “marish” behavior—aggressiveness, impatience and general grumpiness—is more common during estrus because of increased hormone levels.
Why do mares urinate when in season?
During heat, her developing follicles release the hormone estrogen. The estrogen released during heat is what prompts her to act in ways to attract a stallion. These behaviors—frequent urination, squealing, tail swishing, threatening other horses—can hamper her trainability and performance.
Why is my mare so grumpy?
Hormonal Changes Hormones are often blamed for moody mares and abnormal levels of thyroid and adrenal hormones are known to cause fluctuations in emotions. There is also evidence to show that horses are affected by changes in their routine in much the same way as humans.
Why are mares so moody?
One of the most common causes for mares being moody is changes to their hormone balance. As with all animals including us, different stages of the breeding cycle will have an affect on hormone levels. In some cases where these levels can be out of balance to the point of quite dramatic mood swings.
Why is my mare acting like a stallion?
Occasionally mares may show aggressive or stallion-like behavior. Abnormal hormone production may be the cause. Rarely, otherwise normal mares (with normal ovaries), can show stallion like behavior toward the end of their heat cycle. These hormones cause changes in the mare’s behavior.
Will breeding a mare calm her down?
NO! I wouldn’t breed a mare just to calm it down. I know from experience that they come out the other end just the same! Any apparent calming effect is probably due to the mare being 18 months older by the time the foal’s weaned, and just down to her mentally maturing.
When does a mare go on a cycle?
The mare’s normal cycling period is from approximately March through September. During this period, the mare undergoes a series of cycles, each approximately 22 days in length. The estrous cycle is divided into two physiological parts: estrus and diestrus. 3
Why does a mare get cranky when she is in pain?
Lameness or pain “Discomfort can make her cranky,” says Sheerin. “If a mare is in pain, she will show that behavior frequently or whenever she has to work, versus the cyclical pattern of her estrous cycle.” Some mares show colic symptoms because of painful ovulation.
Is it OK to suppress a mare’s estrous cycle?
The timing between treatment and ovulation should be more consistent with normally cycling mares than with transitional mares. The first estrous cycle after a mare foals may not be the most fertile. Suppressing the cycle and allowing more time for the uterus to involute and return to normal can increase conception rates.
What does the term heat mean for a mare?
Common terminology pertaining to the mare’s estrous cycle is as follows: Estrous (œstrous in many parts of the world outside North America) refers to the entire cycle. Estrus (œstrus) refers to the “heat” stage of that cycle when the mare is receptive to the stallion’s advances.

What does diestrus mean in a mare’s heat cycle?
Estrous (œstrous in many parts of the world outside North America) refers to the entire cycle. Estrus (œstrus) refers to the “heat” stage of that cycle when the mare is receptive to the stallion’s advances. Diestrus (diœstrus) refers to the period in between the estrus phases when the mare is not receptive to the stallion.
