My mare who was previously pregnant lost her embryo a couple weeks ago. I gave her shots of lute last thur/fri (1/2 cc each) to bring her back into heat. Vet was out first thing monday morning to palpate. Said she had one follicle, saying it was about a 30. She did not want to palpate again tuesday (although I did, she said unnecessary) and semen was ordered for wednesday delivery. Vet was not out until 8pm wednesday to inseminate. Mare had already ovulated, however we still inseminated. I have no idea when she had ovulated, vet said her cervix was still fairly open and uterus soft. Of course I won't know for a couple weeks if she took. Anyone deal with something like this before? Think I have any chance of her being pregnant? Thanks!

Also wanted to add, mare was give shot of IV SETTLE...

I know how frustrating it is to have the mare ovulate before inseminating. This happened to me once this year, and I was bummed. Not only is it time wasted, but it can get expensive. I hope your mare took.

Please correct me if I'm wrong, I'm still learning. But I believe you have aprox. 5 to 6 hours after they ovulate to inseminate. The uterius is soft and cervix is open for 2 to 3 days after ovulating.

Good luck, let us know if she took.
Marilyn

You are pretty much correct Marilyn :-)

Breedings that take place within 6 hours post-ovulation will have the same resulting pregnancy rate as if they were bred just before ovulation. Between 6-12 hours, there will be a slightly lower pregnancy rate and slightly higher EED rate. After 12 hours, the pregnancy rate drops significantly and the EED rate rises significantly.

The cervix closes in response to rising progesterone levels, so by 24 hours post-ovulation it will be starting to get closed - there will be a variation between mares - and by 3½ days the closure is pretty significant.

Thanks for the info. Well maybe I'll get lucky and we inseminated close enough to ovulation. Fingers crossed!

Jackie always remember your vet is employed by you. The vet does not dictate the schedule, you do. I have vets at my farm flushing mares as early as 4 a.m. and as late as 11 at night. I have had them meet me at breeding sheds to open the caslicks on an older mare and then sew her back up after breeding her. You pay the bills thus you are the boss. I agree with the others, I think you have a good shot, there is a huge QH farm in Ocala who will only breed post ovulation.

Cathy- I am going to be using a different vet from now on. I've had nothing but bad dealings (repro wise) with current vet and it's not worth it. I live fairly close to New Bolton Center in PA and will be using a repro vet from there. There's no excuse for my current vet to not come out to re-palpate when she's on 2 miles down the road!!! Thanks, I'll let everyone know how it goes.
