I have a mare that just foaled 7 days ago and want to breed her back. My question is should I breed her on her foal heat or wait 30 days?
I have never bred on a foal heat. OUCH!
My other mare was bred 14 days ago and I was hoping to get the foals closer together. I would appreciate any feed back on this.
Thanks-Delia

I don't and can't use foal heat. The stallion farms in Ocala do not permit it. So I guess collectively they must have good reasoning behind it. I do know that the probability of abortion is increased in using a foal heat. So I short cycle the foal heat and at 18 days give prostin.

Delia- we have bred on foal heat with some success in order to move up the foaling dates also my understanding is that the follicle will come from the same ovary as what your foal did in this process, the rule of thumb here is, if you are happy with the foal you have, breed on the foal heat, if not, breed on the 30 day heat instead. ( Jos will correct me on this if I'm not correct and I have no hard data to support what I've been told, only local breeder folk lore. :-)

There are pros and cons for breeding on the foal heat, but as a general rule, as long as there are four criteria fulfilled there is little reason not to. Those criteria are:
  • No problems folaing (dystocia, retained placenta, excessive bruising etc.);
  • No abnormalities of the placenta (thick, abnormal colouring, thin etc.);
  • No - or minimal - discharge by about day 7 post foaling, and if there is a little discharge it is colourless or only slightly pink;
  • An ovulation that occurs greater than 10 days post-foaling.
If all of those are in place, pregnancy rates will be about the same as for "regular" cycles, or only slightly lower.

E Watkins... sorry... myth. There is no reason why there would be an ovulation relating to the same ovary as the one that produced the foal. Remember that there are a lot of secondary ovulations occurring during pregnancy as well. I'm not quite sure what you're indicating with rule of thumb either... are you suggesting that there will be a similarity in foals produces from ovulations on the same ovary? One sometimes wonders where on earth these myths originated!!! :-)

I should add that there is an article that discusses delaying foal heat in the articles section that may be of interest and use as well.

Thank you Jos! I read your article.
So far everything is on track. She foaled easy, everything was text book. She had some discharge at day three/four but it was pink tinged or clear. Nothing now. She had no brusing or tearing. She will be day 8 tomorrow. This is a three day cycler. And last year we bred on day 2 with 1 cover and she caught. But, we bred her on day 30, post foaling. She is going to the breeding farm tomorrow so she can have a couple days to settle. And, I hope she doesn't come in early. Nothing so far. Hoping to breed on day 10-11. Wish us luck. I guess I just needed a bit of reassurance on breeding on the foal heat.

Jos- who knows where the KS farmers come up with these things. ( I figured it was a myth ) Thanks for the information! I knew if I was wrong you'd set me straight!
