Very tempting - but I don't venture into the percentage cattle now. I will occasionally use a 3/4 bull on my PB's, but the offspring is considered a PB. I did look up that bull and he looks awesome. Hmmm, nothing ventured, nothing gained.
OK, back on the genetics. Does a WHITE shorthorn carry any red or black gene? I realize he "shouldn't" carry a black gene - but some of these breed genes don't follow the rules. But, what about the red gene?
