1 Markers Assisted Selection for the Canadian Swine Industry

The Canadian pork industry enjoys a solid reputation world wide for superior quality and health status. The Canadian pork exports have continued to increase during the recent years. Canada ranks number one among the pork exporting countries of the world. Domestically, the pork industry is also recognised as a major industry sector in agriculture, contributing to the trade surplus. The Canadian Swine Improvement Program has a proven history of genetic improvements over the past several years. Over 90,000 pigs are tested each year on the Canadian Swine Improvement Program. There are 120 participating herds across Canada and over 9000 nucleus sows. The program involves selection and genetic improvement of three major breeds: Duroc, Yorkshire and Landrace. Over 7,000 new records are added every month in the national database and genetic evaluations are computed for growth, feed efficiency, carcass traits and sow productivity. The swine improvement program is supported and operated by the Canadian Centre for Swine Improvement (CCSI) and member organisations. CCSI is a national organisation created by the swine industry to provide leadership, coordination and services relation to genetic improvement. CCSI operates a research program with industry partners, research institutions and Canadian universities. The current research plan includes integration of molecular genetics in selection programs as one of the key components along with research on selection strategies, genetic evaluation methods and optimum use of genetics by the producers
