I also had a mare who I showed across the country MFT and couldn't afford any antics at a show so we all had the time release pellets put in their necks under the mane. They lasted about 60-90 days depending on the mare. It made them think they we pregnant. After the show season Oct we let them dissolve out. Worked great with no ill effects. I did breed her once with no problems.

I can tell you the story of my mare that acted just the same. It began when I sent her to my trainer's, this spring, for some trailriding training. (She has been a broodmare) Beeper was so bad that my trainer couldn't ride her on the trail with any other horse. She would just stop, squat, pee, and stand for ANY horse. The vet did many tests, said possibly cancer in the ovaries, did blood work, ultrasound, internal palpitation, etc. He did discover one of her ovaries is small and hard and apparently not functioning, but no cancer. He gave her a shot of a hormone that he had compounded for race horses he vets. That helped but not completely. Finally he inserted a sterilized marble into her uterus. Beeper is a 9 year-old Tenn. Walker that has already had three foals (her last colt is a yearling now) and she didn't exhibit signs like this until
this year. So far the marble has stopped her heats and she is back to normal acting. I don't plan to breed her again, so I can leave the marble indefinitely....I believe.
