Removing spotting from white pig lines using genomics

纯种白猪身上的黑斑是加拿大养猪人反复遇到的问题。这导致了客户对动物谱系的信心问题，由于约克郡和长白猪中存在显性的白色基因，预计动物谱系是白色的。这对**出口市场来说可能特别麻烦，因为它使人对养殖场的交配控制以及血统的准确性产生怀疑。这也意味着需要在加工厂对这些生猪进行特殊加工，这降低了猪肉行业的价值。尽管彩色斑点的存在一直是加拿大猪肉行业的一个长期问题，但目前还没有商业工具来解决这个问题。

Black spotting in purebred white pigs is a recurring issue for the Canadian pig breeders. This causes issues in**relation to confidence of customers in the pedigree of the animals which are expected to be white due to the**presence of the dominant white locus in Yorkshire and Landrace pigs. This can be particularly troublesome for**export markets as it causes doubt regarding the control of mating in the breeding farms as well as the accuracy**of the pedigree. It also means that special processing of these hogs is required at packing plants which reduces**value for the pork industry. Although presence of coloured spotting has been a long-term problem for the**Canadian pork industry, there is no commercial tool available to address this issue.
