A breeder friend of mine has been breeding for over 30 years. She has successfully gotten mares to take with AI who formerly wouldn’t take with AI by turning them out with a pony stallion. The pony stallion couldn’t reach the mares to inseminate them but could do all of the necessary foreplay to get them in season and regularly ovulating.
I think there’s something to be said for the stallion’s behavior to get the mare into season in a way that anal ultrasound to determine follicle size can’t.
Thank you for that… She’s tired of fooling with it this year, so going to try again next year. She has spent a ton of money in the last 2 breeding seasons with nothing to show for it. We are gonna do our homework and hopefully next year I can come back here and update this with good news.
I’ve had the same issues with my mare in the past and will be trying live cover for her this year per the vets recommendations. She had bad reactions to AI, but I was never told it could be the Penicillin and that I could have tried having it shipped differently. That would of been nice to know at the time as the stallion I was breeding to is now deceased.
^^ Check out this article about the use of oxytocin for mares with problems like yours and my friends. She is also upset as the stallion she originally wanted to breed to is now retired from breeding. http://www.equine-reproduction.com/articles/oxytocin.htm I think I’m going to insist I get to name the foal she gets from this mare
