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.
在对萨斯喀彻温省一家屠宰场的2500头市场体重猪进行的调查中，37%的猪感染了成年猪蛔虫，46%的猪有乳斑肝病变。总共60%的受检猪有猪蛔虫感染的某些证据。大多数感染猪体内的成年蛔虫不到50条。在对另外2500头市场体重猪进行的第二次屠宰场调查中，44%的动物有乳斑肝病变。在大约12%的患病猪中，这些病变非常严重，并且有非常相似比例的猪肝被判定不合格或送去用作动物饲料。将特别参照猪蛔虫感染对萨斯喀彻温省生长猪的重要性来讨论这些调查结果。
