Ok so my seven year old mare was bred on Saturday via AI with two follicles. One was at 43mm and the other at 35mm. On Sunday she had ovulated off of one side but not the other so vet wanted to continue to inseminate. We inseminated on Monday hoping she would ovulate that day off the other side. This morning we checked again to make sure that there was no fluid and found that she still had not ovualted. The vet was surprised because the follicle was at about 55mm. He said it was the largest he has seen this year. We inseminated again this morning hoping she would ovulate today but the semen was now about 48hrs old with about a 60% motility. What are the chances of her concieving?

First off, don't play the "what are the chances" game. All it will do is drive you nuts. she's either pregnant or she isn't, and there's nothing you can do about it but wait and see
Having said that, continuing to inseminate for several days after an ovulation is a bad policy, as the first ovulation will produce a CL, which in turn secretes progesterone, which closes down the cervix and suppresses the uterine immune response. Consequently, the subsequent inseminations are being put into a uterus that has a gradually declining chance of resisting pathogens introduced, and a reducing inability (due to cervix closure) of clearing excess fluid or inflammatory cells. Overall, a bad thing.
You'll know in 15 days though...

Well said Jos.....you'll just have to wait and see! (And like the song says..."the waiting is the hardest part!")
Our mares never ovulate until the follicles are about 60...your vet would have a stroke with our gals! LOL!

Well with all that said I am hoping it works. We only bred once last month and she didn't take. But if not we will just try again. I will try to relax and not worry about it too much.

Good luck Renee! I know how you feel, we're working on try #2 for my mare. Those 15 days have got to be the longest days of the year!
