Breed-specific haplotypes for polled phenotypes in cattle

Abstract

The presence of horns within commercial cattle populations increases the chances of injuries. The Polled (hornless) condition in cattle has existed since domestication, and it has been selected by breeders because of its economic importance and ease of management. A dominant mutation is believed to cause the polled phenotype. The present invention relates to the identification of breed-specific single nucleotide polymorphisms (SNPs) and their haplotypes, in the bovine genome, in or near gene(s) encoding polypeptides associated with the Polled phenotyped in beef production. The invention further encompasses methods and systems, including network-based processes, to manage the SNP data, haplotype data and other data relating to specific animals and herds of animals, veterinarian care, diagnostic and quality control data and management of livestock which, based on genotyping, have predictable productions quality traits, husbandry conditions, animal welfare, food safety information, audit of existing processes and data from field location.U
