Jos, can you answer this question? I'm very perplexed. I have two mares recently bred. One of the mare's is acting like she's in season again.

My mares were bred aprox. a week and a half ago. It was a textbook breeding. We brought them home from the breeders last Sunday. One of the mares is acting like she's back in season. She's at the fence letting the gelding we use for teasing, nip at her butt. She squeals and kicks at the fence. She doesn't walk away, she lets him do this over and over. I am so baffled about this. Why would she visit the gelding and let him do this, when she shouldn't be in season already, especially since she's been on Regumate since she's been bred.

Can you help? If you need more information regarding the breeding, you'll find it on the thread called "Things are begining to happen". Thanks again Jos!

Marilyn

Without being able to actually evaluate the animal, it would be hard for me to say anything that is going to either be constructive or not put you in a panic... :-)

Save to say, that if she is on Regumate she should not be displaying estrus; and if there really is is an early return to estrus, check her for a uterine irritant - a pathogen or persistent breeding induced endometritis.

Jos, thank you for your quick response and your help. She is a wierd mare. I guess I'll have to wait and see if she's pregnant, then go from there.

In March '07 I got a very thin 16 year old mare. She had 8 foals between 1998 to 2006, then was given away and ended up in a bad situation- She has put on a lot of weight in the past year, but the Vet did not like the fact that her ovaries were small. However she was bred: in foal at 16 days but not at 6 weeks. (I should have done the Caslick & will do next year) but my question is what is the signifigance of small ovaries??

As the mare has had foals previously, and as she is obviously ovulating (per the recent pregnancy), the ovarian size (or lack thereof) meant nothing.

In some younger mares, small - and I mean quite literally pea-sized - ovaries are linked to gonadal dysgenesis ("intersex mares") where there is an error in the sex chromosome (e.g. XO dysgenesis). Those mares are almost always barren though, and usually anovulatory, so that wouldn't apply in this case.

If the mare were in anestrus, it would not be unusual to see smaller ovaries, but she is apparently currently ovulating, and therefore not anestrus.

How small was small? Some mares do just have small ovaries, operational though they be! :-)

The vet thought her ovaries looked smaller than normal (same thing last year when she was so thin) and I think he was doubtful of her coming in season normally. I'll ask for a size comparison when he comes for next visit, (teeth, next month) & hope he remembers!
Thanks Jos-

Jos, Help?

I have a 6 year old mare who lost/aborted her foal last December(4/5month gestation)from contracting Lyme Disease. The vet that examined the mare said that it was from the lyme and not the medication as she was not diagnosed until she had aborted. Now after being cured of the lyme, she is having trouble getting pregnant. I tried pasture breeding in July, August and September and she won't concieve! Any suggestions?

The first thing to consider is that without a necropsy having been performed, it is really impossible to confirm what the foal died of.

Your starting point for re-breeding should be to have a complete breeding soundness examination performed by a veterinarian experienced in equine reproduction - preferably a theriogenologist to evaluate her for existing problems.

Beyond that, anything is going to be pure conjcture, and probably not much use! :-)
