A survey was carried out to identify disease conditions occurring in adult and feeder sheep in Saskatchewan. Necropsies were performed on 50 adult sheep submitted to the Western College of Veterinary Medicine during the period July 1976 to June 1977 and data were assembled from necropsy records of sheep submitted between January 1975 to December 1976. The diseases encountered were briefly described. Conditions of the respiratory and digestive systems were the most significant as causes of mortality. Burdens of helminth endoparasites were generally low. In the flocks included in the necropsy survey, annual mortality among adult and feeder sheep was estimated to be three percent.
