Hi!
I have a bit of a strange situation.
In June I had bred a mare to one of our stallions during her foal heat. The breeding took place over a 5 day period. At the end of that time they both lost interest. I then waited a further 3 days and put the mare and foal in with my other mares and foals who were running with a different stallion. This stallion had her in heat again within 2 days and proceeded to breed her. She has not cycled since. At the time I was puzzled as to how she could have come in heat again so soon, and my vet couldn't explain it either, but was not overly concerned.
Just this weekend I noticed some strange flecks of yellow on her legs, almost like light yellow chalk paint. There was no sign of discharge from her vulva though. This morning I saw her discharging and teasing the stallion, who squealed, but made no move to mount her.
My vet will be coming out next week to check her and we will run a blood test for pregnancy/ hormone activity. I just wondered if anyone had any theories on what could have gone on here? She should be 4 months pregnant.
I don't tend to scan the Spanish Mustang mares, as the mares are not used to being handled much by strangers without sedation and twins are relatively rare in the breed.
Could it be that she ovulated twice in 2 weeks and conceived twins in June, which she has now aborted and she is just cycling again? Or could it just be a hormone spike?

Martine, It could be that she either didn't conceive the first time or she did conceive and let the 2nd stallion breed her out of submission. Some mares will let a stallion breed them even if they are not in true heat. It's really hard to say if she's pregnant and all's well or if she's open and aborted or was never pregnant at all!! Having the vet come out is probably your best bet and if she is pregnant then I guess your next step is figuring out who daddy is!. Keep us posted on your outcome.

Little update...I just watched stallion 2 breed her, so I guess she might have aborted and has just come back in heat at the last minute... will be a late foal this time I guess! Will have her swabbed anyway just to check everything is Ok in there I think...
