When I was farming with my dad and brother, I took a course at college to artificially breed cows.....when I returned to the family farm, I took the place of a couple of people dad paid to do the "service". Not only did I artificailly breed our 300 head cross-bred cow herd.....I got paid to do the same service for other farmers cows in the area.
When Michigan State University did testing on our cow herd and fertility expieriments (Lutalyse and Synchro-mate B) I was pretty impotent...err I mean important to their testing.
