Some of our heifers we kept back have I-80 either as either sire or grand sire on either side of pedigree. A lot the popular calving ease clubby bulls also have I-80 bloodlines. What is everybody using on their hfrs that wont be to close related. A couple heifers i plan to sell as breds so should be something buyers like to i suppose. I have angus semen as last resort but wouldnt mind something else. Thanks
