I am currently trying to get my 7 year old maiden mare in foal (I'm in Australia). She is the same mare that I posted a question about regarding AHF last year. She had a granulosa cell tumour removed almost two years ago. For three cycles in a row now, she has ovulated before I have had a chance to get her scanned. The first time she showed some signs of heat for a day, probably just around ovulation and since then she has shown no real signs (perhaps a milder negative reaction to the teaser), but seems to be ovulating according to the CL on the scans. Do you think that this might be due to a problem with her remaining ovary?
She had a shot of PG two days ago (scan showed a 20 millimetre follicle and a CL), no change in ovarian activity today, so we are going to scan again in 5 days and then PG again if no action. I plan to have this mare AI'd. Do you think there is any chance of her maintaining a pregnancy, even if we do manage to work out what her cycles are doing? Any advice would be much appreciated. Thank you.

OMG! Sounds like Feb 2001 for me! I had a then 9y/o TB mare that I was going breed. I was working with the best Repo vet in my area and we had quite a bit of trouble getting her cycle figured out. She was cycling quite quickly and we kept missing her cycle. We started breeding her in Feb - missed her, bred her in march - missed her, bred her is april(thought we got her) - missed her, bred her yet again in May - Got her!!!! Yeah!, talk about happy, and yes this got quite expensive with her being AI'd each time. Then there is also all the palpations and ultrasounds done to check when we should breed her and to check if she was in foal. We also tried the PG shot after using Regumate - did't work for us. She was on the track for quite a few years and my vet suggested that the drugs that she could of been on were still possibly playing havoc on her system. He also suggested that she just plain wasn't ready. I knew going in to this that mares that are bred later in life have a lot harder time getting and staying in foal, but I liked her so much and wanted some foals out of her, I gave her a chance. I don't think I would have attempted the next year with her, had she not conceived. I kind of gave her the 2001 breeding season to get in foal or back to riding life she went. I think she just wanted a spring baby! As long as your vet doesn't see any reason why she couldn't conceive and maintain a prenancy, I say go for it. Breeding takes a lot of patience and money, esp. with some of the mares we love.
