In a survey of 2500 market weight pigs in a Saskatchewan abattoir, 37% were infected with adult Ascaris suum and in 46% there were milkspot hepatic lesions. A total of 60% of the pigs examined had some evidence of A. suum infection. Most infected pigs contained less than 50 adult ascarids. In a second abattoir survey of a further 2500 market weight pigs, 44% of the animals had milk-spot hepatic lesions. In approximately 12% of the affected pigs these lesions were very severe and a very similar proportion of pigs' livers were condemned or sent for use as animal feed. The results of these surveys are discussed with particular reference to the significance of A. suum infection in growing pigs in Saskatchewan.

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.

Four cases of fatal diaphragmatic rupture in the horse are described. In 2 cases there was no history of injury but the other 2 animals had sustained recent thoracic trauma. Three of the horses had signs of colic and bowel obstruction complicated, in 2 cases, by respiratory embarrassment; the fourth died rapidly, presumably of shock. Previously published cases are reviewed and the causes, clinical effects, diagnosis and treatment of the disorder are discussed.
