I'm wondering if there are any good websites or books out there that give you beginner instructions on how to use an ultrasound to determine pregnancy in mares, and also how to use an ultrasound to predict ovulation. I realize there are courses out there that individuals can take but I'm several hundred miles from most that I've found listed on the net.
I caution you on self teaching yourself on the use of an ultrasound, not so much on how to use the machine but the mortal damage you can inflict on the mare by rectally examining her without proper instruction, you must use extreme caution not to tear the mare which in most cases ends tragically. You can generally do a fairly good job of predicting ovulation by examining the cervix which is much tougher tissue and not easily damaged, however in this examination you want to use caution not to introduce any bacteria or contamination which could flow into the uterus. Then on pregnancy determination if you have access to a stallion the mare will give you a pretty good idea if she is pregnant or not by checking her on her next cycle time. We used this method for AI several years before we purchased our first ultrasound.

Thanks for the info, I've been breeding A.I. for several years and am farmiliar with the differances in the cervix, and the fact that it is very easy to rupture a mare when palpating. However in the past I have had mares that would show heat while they are pregnant and would also accept a stallion. In fact I have three of those here right now. Anyways I have a vet about 3 hours away that has been doing ultrasound for me for several years who is going to teach me the proper methods when time permits. I was just hoping to find some referance material on the internet to read on for the mean time.
