I keep reading posts here that say there is no consistency in calves unless you use a purebred bull. I am no expert on the subject, but my observations make me question that. An example is Gibbs Farms in Alabama. They have about 800 mama cows. They have been breeding simmental and sim-angus for almost 30 years. Most of their cows and most of the bulls they use are Sim-angus. Some purebred simmental and a few purebred angus, but mostly the crossbred. Their calf crop is uniform. They had their 15th annual bull and female sale last November - selling about 300 head per year now - herd bulls and replacements. They average around $4000 on the yearling bulls - selling all over the US. They send their steers to the feedlot with retained ownership for over 15 years and get carcass data back on them. They have sold many bulls into the AI studs. They seem to be successful with their crossbreds.
