I purchaced a mare two years ago March. She never had been in foal even though they tried a few times. I got her in foal after a couple covers. She foaled rather eventfully, it was a really hard labor. She had a lot of tissue damage on her hip, extremely swollen for a week. I obviously chose to skip her foal heat and give her a full exam before attempting to breed again. I only bred her one time with no success. I called the breeder that bred her dam several years,and they said that her mother was an every other year breeder. She would not get in foal if she was nursing. I had a friend that had a mare that did this also. Is it hormonal or what? These mares are ovluating and healthy. Thank you, Julie

Most mares that have lactational anestrus will conceive if bred on their foal heat only. I believe that it does have something to do with hormones but I'm not sure what. Have you talked to a vet about this?
We have a couple of mares that will conceive, but not keep a pregnancy while they have a foal at foot. One of these mares has lost two foals after birth, and stayed pregnant, but while she's feeding one, she just won't grow another.
In my experience yes, some mares will not conceive every year, I would think it would be hormonal, however if she is showing signs of being in heat, and has access to a stallion or a great teaser, that would help in getting her 'thinking' about getting in foal! I have not had any that would ONLY get in foal on their foal heat, I have chosen to skip that with many because of either difficult foalings, or because I felt they needed more bonding time with their foal and not have to deal with the stress of a man in their life again so soon! You might want to contact an experienced breeding vet, you might need some hormone therapy if you want to breed every year and she is geared that way, but I'd try and see if you could have her exposed to a stud oftern, to help her come in strong heat first before shooting her up.
Good Luck! Jenn
