I have a 14 year old TB mare which we failed to get in foal last year. (She was/is a maiden.) She came into season and showed well in January - far too early for us!
From April, we only managed to catch her in season once - and she showed and stood for less than 24 hours. We covered her - no good! We PG'd her three more times - she failed to come into season (or if she did, she kept it very quiet!)
Now we're trying again. Again she was showing in season in January! At the end of April, we PG'd her - and she stood for 24 hours. Got her covered once - not in foal. Scanned her last Friday, there was a 35 mm follicle on the left ovary. Teased her and teased her until the stallion nearly went on strike - nothing! Scanned her again today (1 week later) and there's a 55 mm follicle on the left ovary - but my vet didn't like the look of it and says he thinks it's a persistent follicle.
Any suggestions on the best way to get this mare sorted?
Well - she's sorted. We got rid of the follicle and I sent her to Twemlows (big AI centre with a very good stud vet!) They scanned her and scanned her - then AI'd her - and she took first time!
So she's now in foal to HM The Queen's coloured stallion, Oberon and came home today! I'll worry about next year, next year!

I guess my suggestion would be to send her to the Matson's
For future reference... there is an article about annovulatory hemorraghic follicles on the web site. About 85% of them will develop luteal tissue and respond to prostaglandin, while the remaining 15% will not, and all you can do is sit and stare at them and swear about them for the next two months or so until they resolve. AHF's as a whole are typified by a large size, and echoic matter in the fluid. Very distinctive on ultrasound.
Nice idea - but defeats the purpose of having my own stallion somewhat. Tullis is coming down to have a go at teaching my boy to ground collect (not worth spending a FORTUNE on equipment I'll use a few times a year)and if it works .......
It looks like her biggest problem is the silent heats - but if we scan her often enough and AI her when she's READY - I should be able to get a PROPER (Irish Sport Horse) foal from her.

Good... Say hullo to Tullis for me (he probably remembers me as the somewhat crazy Canadian that freezes semen ). If your stallion will ground collect, then if you're only inseminating your own mares on farm, you can certainly get away with a bare minimum of equipment.
Good luck, and let us know how you make out!
