There is an A.I. DVD for sale here on Ranchers. Scroll down on the main page. I've wondered if it was any good. I went to a school years ago put on by local ABS rep. It was a lot of work for him as there were a dozen or so cows to practice on. A.I.'ing is like anything else, you learn the basics but practice makes perfect. I have a better outcome by hiring someone to do it...but I rarely use A.I.
There was a South Korean company that manufactured an interesting A.I. tool. It held your gun and allowed the inseminator to actually see the cervix for correct placement. I watched a video on it but never ordered one. It was a little expensive.
Can you find someone locally who A.I.'s and would be willing to teach you..a one on one class on a Saturday sort of thing? $$$ talks!
