alacattleman,
Not many. The breeder in the link Keren has provided is the closet one along with one of there neighbors down the street that has a different line of Shorthorns.
Killala,
That semen is conveniant and available locally. So, I had considered it because my calves are all terminal. But I do need them to be at very good weights at or around 12-15 months. I can see in the graph that he wouldn't be good for my operation even for terminal calves. Thank you very much for your advise.
