The present investigation was undertaken to determine the prevalence of common intestinal parasites in domestic pigs in Shaanxi province of China between May 2011 and February 2012. A total of 1339 pig fecal samples were collected from pre-weaners (252),growers (360), fatteners (417), breeding sows and boars (310) in 9 farms located in 8 counties/districts. Among them, 387 fecal samples were positive for intestinal parasites. Growers had the highest infection rate (41.4%), while pre-weaners had the lowest(22.2%). But only 39 pigs were infected with multiple parasites. The common intestinal parasites were Ascaris suum (10.23%), Strongyloides spp. (6.49%), Eimeria spp.(6.35%) and Cryptosporidium spp. (4.63%). Of the risk factors for intestinal parasite infection investigated in the present study, the farm management system played a remarkable role in the occurrence and intensity of intestine parasite infection. These results suggested that the efficient prevention and control measures should be taken to control intestinal parasites infection in pig in Shaanxi province.
