Swine ascariasis: impact on production


, : Swine ascariasis: impact on production. Acta Veterinaria Scandinavica (Suppl. 84): 265-267

In a study of 386 pigs from 15 herds on Prince Edward Island faecal samples were examined at 11, 15, 19 and 22 weeks of age and again at slaughter. After slaughter the carcass weight and pneumonic and liver lesions were recorded and any atrophic rhinitis. The study showed that 133 (34.6%) pigs had intestinal ascarids and 82.4% had milk spot lesions on the liver. Milk spots occurred in the absence of intestinal ascarids in 51.3% of the pigs.
