Infection with gastrointestinal helminths has been a key factor affecting profitable animal production globally. Pig production in Nigeria has been adversely affected by presence of endoparasites. However, type of husbandry system can affect the prevalence of the parasites, thus, there is a need for this study to look at the prevalence of gastrointestinal parasites in the production of pigs in this tertiary institutional farm in Southwestern Nigeria. Faecal analysis for intestinal helminths was conducted on the pigs using saturated sodium chloride floatation technique. One hundred and fifty faecal samples were taken with only Ascaris suum, Oesophagostomum spp and Trichuris spp ova identified in single and mixed infection. The overall prevalence rate was 20%. Mixed infections remained more dominant (15.31%) with Ascaris suum having the highest occurrence as a single infection (3.33%), followed by Oesophagostomum spp (2%) and Trichuris spp (1.33%). Females had higher prevalence of nematode infection (14.67%) compared to males (5.33%). Comparing breeds, Large White had 14.67% prevalence of nematode infection which is higher than that of Duroc (5.33%). Weaners had no presence of helminths, whereas growers had the highest prevalence (9.33%), while piglets and adults had the same prevalence of nematode infection (5.33%). One of the factors that affect good productivity in pig farming is low presence of helminthes. Pork eaters are hereby encouraged to buy their meat from institutional farms as they produce safer meats for consumption.
