After using a bull for 3 or 4 years , many breeders pack the bulls in order to replace them with different bloodlines or younger bulls---I have often thought that it would work to my benefit to purchase some of these older bulls to use in my herd ----I have bought many young bulls and many do not develope as I hoped----with that in mind , I would appreciate any help that might be offered---I am interested in Shorthorns , heavy in commercial traits----horns or polled, red, white or roan makes no difference ---as long as they produce thrifty, productive cattle.......Any ideas how to locate such bulls?
