Prevalance of Gastrointestinal Parasites of Domestic Pig ( Sus Scorfa Domesticus Carl Linnaeus, 1758) in Two Farms of Pokhara Valley

Abstract

Parasitic infection in pig is a common global burden causing loss of production and several parasitic diseases to them. The present study was conducted to determine the prevalence of gastrointestinal parasites (GI) of domestic pigs in two farms viz. Phursekhola pig farm and Saaru pig farm of Pokhara. A total of 120 faecal samples were collected by opportunistic random faecal sampling method. Iodine wet mount and different concentration technique (floatation and sedimentation) were used for faecal qualitative tests and verbally administered questionnaires for interview. Out of 120 faecal samples examined, 73 faecal samples were positive with 60.83% prevalence of parasitic infection. Total of eight GI parasites that includes protozoan: Isospora sp. (8.33%), Eimeria sp. (5.33%) and B.coli (25%) and helminths: Ascaris sp. (10.83%), Trichuris sp. (20.83%), Strongyloides sp. (8.33%), Trichostrongylus sp. (10.83%), and Fasciolopsis sp. (1.67%) were identified. Statistically, the difference in GI parasitic infection in specific parasites were found to be insignificant (χ²=38.083, P>0.05). The prevalence rate of protozoan parasites (39.17%) were higher than helminthes parasites (21.67%). Statistically, the difference in prevalence of GI parasitic infection among Protozoans and Helminthes parasites were found to be insignificant (χ²= 3.505, P>0.05). The higher prevalence of GI parasites was in Saaru pig farm (71.67%) and the lowest was in Phursekhola pig farm (50%). Statistically, the difference in prevalence of GI parasitic infection among study area was found to be insignificant (χ²= 1.11, P>0.05). Whereas the difference in prevalence of single infection (64.38%) and mixed infections (35.61%) were insignificant (χ²=3.50, P>0.05).
