Dairy genetics company unlock polled geneSupplied Hornless heifers born last season from CRV Ambreed's polled programme on a South Island farm. CRV's goal throughout its polled genetics breeding programme was to breed bulls that had two copies of the polled gene, CRV research and development manager Phil Beatson said. "When the bull has two copies of the polled gene, you are guaranteed the bull's progeny will all be polled as all get one copy of the poll gene. Polled bulls progeny will not need to be disbudded, the process of removing horns from calves. Two of CRV's polled bulls are holstein-friesian/jersey crossbreds and one is a holstein-friesian bull and the company will continue building up its homozygous polled bull team.
