Prevalence of Internal Parasite Infection in Pigs and Analysis of Risk Factors in Smallholder Pig Farms in Cavite and Batangas, Philippines

Mildred A. Padilla | Rio John T. Ducusin



In order to determine the prevalence and associated factors for infection of pigs with internal parasites, a cross-sectional study was undertaken in 65 smallholder farms in Cavite and Batangas, Philippines. Fecal samples were examined by flotation and sedimentation methods. Data on potential risk factors for infection were collected using pre-tested structured questionnaires and analyzed using appropriate descriptive and univariate analysis. Overall prevalence was 29.1%, with Cavite and Batangas farms having 29.6% and 28.9%, respectively. Hyostrongylus rubidus accounted for 13.8% of infection, followed by Trichuris suis and Stephanurus dentatus, each with 3.1%, and Ascaris suum and Eimeria spp. with 1.5% each. About 23% were infected with single parasite type and 6.1% with dual infections. None of the factors studied were associated with infection prevalence.
