I'm just curious of the cattleman who don't ever buy a bull from a breeder, rather they use their own stock to raise herd bulls through AI or ET. I personally like to throw different genetics into my herd every couple years, and buy a bull from an outside source. I had a guy tell me that if he was AIing he would never buy a bull again, and it kinda puzzled me, wondering if I was the minority. I keep replacement hfrs every year so the genetics are always changing, and I AI 95% of my cows, so the bull don't have a real tough job if you think about it.
