hi,
I have an 18yr old mare that has has a foal about 4-6 yrs ago.
I tried to breed her 2x this summer. She caught the first time but upon ultrasound at day 15 the vet said the pregnancy looked unhealthy and it would be best if she did reabsorb. The uterus looked like the walls were a little thick

Next pregnancy she was confirmed in foal on day 17 with ultrasound.Everything was healthy looking
Now 52 days later she is open.

What can be done to help her retain a pregnancy for next summer?

Jos will definitely be able to give you a fuller answer, but has the mare had a full breeding soundness examination?

Did she have a culture and cytology and/or biopsy done? Jos has a great article on the site about culutres/cytologies; give that a read. A biopsy might show that she has fibrosis or other changes of the endometrium, which might require treatment before she is able to carry a foal to term.

A full BSE will give you a good starting point, as to where you should go from here.

I actually thought I had responded to this post, but apparently it didn't maintain... :-(

First, before doing anything next year, make sure that your mare is indeed not pregnant, as she was checked at the early stage of the point where the pregnancy can be missed.

Next - tell us what you have done so far with this mare, so that we are not going to be reinventing the wheel when making suggestions! :-)

The whole work up was done with this mare. I had posted a while ago about her. It was thought that she had 2 cysts and this is why she would not get pregnant in the first place. First vet said he could not map the cysts as they were constantly moving????

She can get pregnant by the looks of things so I had my present vet check her, he did a rectal and said there is no way she is in foal at 52 days.

So back to square one.
Is there a chance this vet missed a fetus by doing a rectal palpatation?

Constantly moving cysts? Sounds a bit odd/unlikely.

What was the grade of the endometrial biopsy?

It is a possibility that a pregnancy was missed - hence my recommendation that you check again before doing anything radical in the spring.

There is more information and comments about this mare's "moveable cysts" in the thread to be found here.

I just wanted to add an experience I had when the vet ultrasound my mare at 19 days post cover and said she was open but had a cyst--well 11 months later that cyst was born-- a big healthy colt
i would get her rechecked

I think I would have her re-checked also. I had our mare U/S at 30 days - told me there was nothing- I had her re-checked at 60 days by a different vet- he said he didn't think she was preg.either. Blood test results yesterday say she is about 120 days pregnant.

Man you guys really make me think, I had a similar situation this summer. I had a broodmare on lease, long story short after 2 breedings and cultures, cytologys, she was not pregnant. I sometimes wonder????? I sent her back in July, she has not come back into heat since the last breeding, July 1st, but being an older mare I was told that she could not be cycling normal, I suppose only time will tell. I REALLY wish I could be surprised as some of you folks have been!!
