I have an older mare who was left open last year as she aborted in August and I want to breed her this year via shipped semen. She had her first cycle (but not a regular for her 5 day heat) about three weeks ago and was ultrasounded yesterday as not in heat (tone of uterus taut and firm), the remnants of a CL and a 2.0 follicle on one ovary. Any ideas when it should be big enough to breed her on?
Well, she came in strong on May9th (almost 3.0 follicle), and was bred the 12th with all things perfect- follicle, ovulation and excellent semen. Wait and see.....

Angela - Follicles grow an average of 3-5mm per day and they can ovulate on anything over 35mm (but usually bigger). Good Luck - post when you check her in 14 days. I bred my mare by AI yesterday so if all goes well, we'll have mares with the same due date!
