Inseminating twice in one day?

[GracefulHano]

I am just curious as to what everyone else thinks. We bred my mare on a soft 45 this morning (around 11am) and the vet wants to come back and breed her again at 5pm. I not sure how I feel about that. She gave deslorelin at 10am yesterday. Then she will come back and check to see if she has ovulated Sunday morning?

I am relatively new at breeding, but have always inseminated next day if the mare hadn't ovulated, and if she had, then leftovers in the garbage. Now it's of the idea, we have two doses lets put them both in?

Don't do it. There is no point. The semen that is already in the mare is perfectly viable and has a better chance of doing its job than the second dose which has sat in the fridge for an extra 6 hours. You'd be sticking in a bunch more fluid for no-reason-at-all.

If you're using the same repro vet as I did, I am floored she would suggest a second breeding in one day - she's usually not a big believer in over-doing things. What exactly is her reasoning??!

My mare ovulated almost a full 48 hours after insemination in 2007 and still caught. The semen you've already put in doesn't magically degrade or disappear, there's not much point in putting in more, *especially* not this soon. If she hasn't ovulated by tomorrow early afternoon, then yeah, put the second dose in. But then oxytocin the crap out of her.. lol.. literally! :D

ps - don't wait until Sunday morning to re-check. Check her tomorrow afternoon.

If you've already got semen in the mare, don't flood her with more! I don't see ANY benefit to a second insemination the same day -- only negatives.

Agreed, don't do it. It's more fluid that your mare will have to clear.

I assume your using Fresh/cooled, not frozen? I've heard of some vets doing that with frozen, but never fresh cooled.

Another absolute thumbs down on that idea.

Agree with you and above posters. We do 24 hrs in between breedings if mare has not yet ovulated. The semen can live for days so there is no sense to increase the inflammatory response to breeding. If she hasn't ovulated tomorrow you can do the second dose but I think your concerns are perfectly valid, for fresh semen! :) (for frozen I believe it doesn't live that long so you have to increase the frequency)

No, for all the reasons given above. Time to educate your vet. :yes:

[Sugarbrook]

NO, absolutely not. I just wonder what your vet is thinking.

If you inseminate before 24 hours, and the post insemination inflammatory response has had time to clear, as Kathy, Equine Reproduction says, you might as well just dump it on the ground.

When the uterus is inflamed, it will instantly kill off the new semen you put in, so no benefit, and a lot more adding fluid for nothing - not to mention another vet call $$.

[GracefulHano]

Thanks everyone! Totally along the lines of what I was thinking.

Boy does that vet clinic ever hate me. I always want things done MY way LOL

[Fairview Horse Center]

Why not check her Saturday morning to confirm ovulation, inseminate the 2nd dose if she is hanging on, and check to make she she has cleared the fluid. :D

I always want things done MY way LOL


Yup! Me too!

It's not your way though...it's the right way! Sometimes though, it's hard to convince a veterinarian of that. :rolleyes:

They don't want to have to come out both days on the weekend. As I have another mare to be checked Sunday for a Sunday night/Monday morning breeding.

She is confident that mare will ovulate, so much so that she even told me if she had ovulated when she came back this evening, she would have insemintaed her anyways. :eek: I will settle for checking for fluid Sunday, will keep the semen just in case (will be an interesting science experiment!).

I love my vet clinic, and while they're protocols are different than mine, as long as they are willing to be flexible, I will stay happy!

We are so lucky to have our vet... our mares this year have all been going so that we are ordering Friday and breeding Sat/Sun... our vet never blinks and eye, and lives an hour+ from us... our last vet wouldn't check or breed on a weekend without an emergency call, and we missed so many mares because of it (found on Monday it was too late to order, etc). ugh. :)

Heck, if she ovulates tonight you are golden! No need for the second dose anyway! :) Sounds like you have got the exact idea. ;)

You know, I have a GREAT veterinarian and clinic, but sometimes your gut tells you different than what they say. There would be absolutely no benefit as others stated to breed twice in one day (I feel the same way for putting both doses in at same time). If the mare has an inflammatory response or just retains fluid due to volume then your screwed not her, excuse the pun. This is the same ignorance of "if a little is good than a lot is better..." shame on your vet and kudos to you for recognizing that you were given incorrect advise.

I would do the Oxytoccin protocol and keep 2nd dose in fridge. If mare hasn't ovulated tomorrow then check semen first under microscope if any still alive and if there is at least 20% motility then if it has been at least 24 hrs from first breeding, I would insemminate with second dose. If semen is crappy next day and very few if any moving, then most times I don't put it in. I figure then that you're just adding junk to her and therefore would be risking too much. Best wishes.

When we bred Hailey we waited 24 hours between inseminations and UC Davis confirmed she'd ovulated.

[RiverOaksFarm]

Another no. Inflammation would be my biggest concern, as Signature said.
