Removing spotting from white pig lines using genomics

纯种白猪出现黑斑是加拿大猪饲养者经常遇到的问题。由于约克郡和长白猪的白色基因位点占主导地位，这导致了客户对动物血统的信心问题。这对出口市场来说尤其麻烦，因为它会导致对育种农场交配控制以及血统准确性的怀疑。这也意味着包装工厂需要对这些生猪进行特殊处理，从而降低了猪肉行业的价值。尽管有色斑点的存在一直是加拿大猪肉行业的一个长期问题，但没有可用的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.
