My 13 year old daughter (at the time, three years ago) went to ABS breeding school. She was the smallest, youngest but I think, got the most out of it. ABS does a great job, three intense days at the stockyards, so we got to see a lot! She has the best averages, I think, out of all of us. My husband went to ABS several years ago (maybe 5?), and is also very good at it. When he took it, they were all at night so he did not have to miss work, and it was over 5 days, if I remember correctly!
I agree with Leanbeef; you need to put your arm in a lot of cows to feel comfortable about it. But with all three of us here breeding, sometimes that is difficult! I get the least amount of breeding time, but I bred dairy cows years ago (like 25) so I can step back and let them do it (thumbsup)
