On monday 02-20-06 I put our 16 year old mare ( who was obviously in heat) with our stallion. He bred her the same day. After 4 days she seemed not in heat anymore. I decided to leave her in with the stud since they got along great and he enjoyed having a buddy around. They didnt breed after the initial first 3 days ( to my knowledge). Today I decided to take her back out, but as soon as I tried to lead her away, she started acting like she was in flaming heat. I left her in just to see what would happen and sure enough 20 minutes later he bred her and she stood there for him. As a matter of fact she follows him around everywhere. It has only been 10 days since he bred her last week and she clearly came out of heat, but is back in already. How can this be ? This mare didnt take last year. We had to rebreed her twice, but then after 8 months she turned out to be open. Any suggestions ??
Has she been under lights? Have you documented an ovulation this spring? If not she's probably still in transition, where they're just getting warmed up and may show heats but usually they aren't regular and they don't ovulate. I think for mares that haven't been under lights the average first ovulation of the year is closer to the end of march first part of april so that may be why
Our horses are not under lights. We had a very warm winter. 2 of our younger mares actualy never stopped cycling over the winter. Now, wether they ovulated or not is another story. It could very well be that she is in transition. I was just a little puzzled
