This study was designed to determine the prevalence of gastrointestinal parasites of pigs within three district of Jos South Local Government area of Plateau state, Nigeria. A total of 200 pigs were sampled. Faecal samples were analyzed using the saturated sodium flotation method. A total prevalence of 31% was recorded; with Ascaris suum 12.5% followed by Oesophagustomum 12%, Strogyloid Spp 3%, Eimeria Oocyts 3% and Strongyle Spp 2.5%. There was higher prevalence in female (58%) than males (42%), and also higher prevalence in adults pigs (35.7%) than young pigs (20%) which was significantly different (P<0.05). There was also higher prevalence in Du district (32.5%) than Vwang and Kuru (30%) but was not significant (P>0.05). This study therefore confirms the prevalence of gastrointestinal parasite in pigs and it was therefore recommended that farmers improve on their bio-security and also adhere to routine de-worming regimen.
