RM Matheson Farms is proud to have the longest traceable lineage of purebred pedigrees in Canada.  We have been on the national performance testing program since 1974 and have had a competely closed heard since 1976.  We breed purebred Yorkshire, Landrace and Durocs and try to maintain up to six lines of each breed.  By maintaining more lines we keep the amount of inbreeding to a minimum.  Our genetic herd was known as Swine Genetics Ontario (SGO).   We have now merged with Alliance Genetics Canada (AGC).
