Abstract:

A cross-sectional study was conducted to determine the prevalence of endoparasites and the factors associated with the risk of infection in smallholder pig farms in Sariaya, Quezon. From a convenient sample of 36 farms in three rural villages, freshly voided feces were collected and examined microscopically for parasites. In addition, interviews using a pre-tested structured questionnaire were conducted to collect data on factors likely affecting the risk of infection. Thirty-one farms (86.1%) were infected with one or more types of endoparasites. Six helminths and four protozoan species were identified. Four of these parasites had zoonotic potential namely, Balantidium coli, Ascarissuum, Fasciolasp. and Trichurissuis. Stephanurusdentatuswas the most common species recorded (25.8%). Multiple infections with two to five parasite species were more common (58.1%) than single infections. None of the factors studied was associated with the presence of endoparasites. Nevertheless, the high infection rate and wide spectrum of parasites that are of economic and/or public health importance point to the need for prior fecalysis and regular treatment of animals with appropriate and effective anti- parasite drugs combined with adequate sanitation and farmers’ education.
