My mare foaled Mon 2/12 in the morning. Mon 2/19 - she was in heat & would have stood to breed. Tues 2/20 - Had the vet out, u/s showed some edema but vet could only find a 24 follicle. Vet suggests re-u/s on Friday 2/23. I double check he wants to go that long with her showing heat already, but he couldnt find anything else going on. Weds 2/21 - Mare is showing to anything with legs, the resident stud, dogs, humans, whatever. I call the stud owner (who's about 20 min haul away), he suggests breeding Thursday 2/22 since she had nothing going on the day before. It seemed reasonable to me. Thurs 2/22 - Teased her and you guessed it, out of heat and very obvious about it. I tried leaving her in the stall next to the resident stud for 15 min just in case, but nothing.
*sigh* So what could have happened? There was another follicle? She grew 15mm over night? She ovulated on a 30? All of these are somewhat uncommon arent they?
I canceled the appt for this morning thinking I'd be seeing my vet daily to track the next heat cycle, but maybe I should have kept it to confirm she ovulated? Anything I could/should be doing differently here?
Also, when they talk about foal heat & the number of days post foaling, is the day they foaled day 1 or day 0?
You are lucky. I never us the foal heat. Mares are more likely to abort that fetus than in any other heat. Think about it, did you want to have sex 9 days after giving birth? Just short cycle the foal heat, I am doing that right now with two mares.
Anthropomorphizing? We are all animals. Common sense, ( pun intended), tells me that many mammals, would benefit from a slightly longer time to recuperate from the rigors of birth than 5-9 days. ( I warn you...do NOT try to tell a mom of two that "rigorous" does not correctly describe birth.) I've seen enough equine births now to know it's no day grazing in clover, either! LOL
Your hypothesis doesn't match nature or research - at least as far as the equine is concerned (and that is all I am referring to!) - so yes, I am telling a mom of two, because I don't want readers of the board to get an innacurate impression that I agree with your observations!! I don't!!
I should also point out that I did observe that in order to achieve maximal pregnancy rates on a foal heat breeding one of the required criteria is an ovulation that occurs at least 10 days after foaling (not 5-9).
Nature is cruel...but I gently contend that the breeder should not be "red in tooth and claw" if at all possible. Is it not true that foal heat breedings statistically produce less viable pregnancies than later heats? Has that hypothesis changed? Do broodmares in captivity live longer than their counterparts in the wild?
