A cross-sectional study was conducted from November 2016 to April 2017 with the objectives to investigate the prevalence of gastrointestinal nematode parasites of pigs and associated risk factors in a total of 384 pigs from privately owned intensive farm in kolfe keraniyo subcity, Addis Ababa, Ethiopia. A simple random sampling technique was used for selecting the sample unit and chi-square test was used to determine the association between the infection and the risk factors. For the determination of gastrointestinal nematode parasites randomly collected faecal samples were examined by sodium chloride floatation techniques and the overall prevalence of 51.5% (198/384) nematode parasites were recorded. The examination of faecal samples revealed the eggs of three different nematode parasites, namely Strongyles (23.2%), Ascaris suum (17.4%) and Trichuris suis (4.2%). Mixed infection by at least two parasite species was observed in 6.7 % (26/384) of the pigs out of which 5.9% of the samples were positive for both Ascaris suum and strongyles species and 0.7% were positive for Trichuris suis and Ascaris suum. The highest prevalence of nematode parasites was recorded in moderate body conditioned pig (72.0%) followed by good body condition (52.0%) and least in fat (41.5%). This difference in prevalence was found to be statistically significant (χ2= 6.823, p=0.033). Moreover, there was significant difference in infection rate with nematode parasites among different age groups of swine (p= 0.000) being higher in piglets (69.5%) followed by adult pigs (45.3%) and list in grower pigs (39.8%). However, lactation stage, pregnancy status and sex were found to have non-significant effect (p > 0.05). This study indicated that pig’s parasites were a major problem in the study area, hence implementation of strategic control measures and appropriate hygienic management systems are recommended to reduce the prevalence of parasites.
