Hello, I am getting ready to breed a mare that was left open last year. she has not shown heat yet, and I was going to have the vet out to do an ultrasound. Can a vet get a good idea of WHERE she is at in her cycle this way? Or are there certain times in her cycle where it is a shot in the dark? We are doing AI so I need to know WHEN it is time. Thanks!
Ultrasound is the only reliable technique, and it still requires a qualified technician to follow the growth of a follicle and acurately predict ovulation. If she's not showing heat, then you are probably right, it's not time yet. And you will not be able to judge when ovulation will occur based on a single ultrasound. As a rule, the vet will have a good idea where she will be after the first ultrasound, but as she gets closer to ovulation he will probbaly want to come by daily to check her progress. It can get a little pricey, But the alternitive is to spend even more by missing the ovulation and have to pay for another semen shipment. (how'd I do)
