Description |
As being part of an ongoing project, assessing animal health and food safety risks in smallholder pig value chains in Hung Yen province of Vietnam, the presence of endoparasites was investigated in a repeated study. Three communes, with a total of 545 smallhoder pig farms, from three districts were selected. In each commune, ten farms were randomly chosen. On farm data including farm management and biosecurity measures were recorded by using a checklist and observations. From each farm, one pooled fecal sample was collected from a randomly chosen barn monthly and followed from June to December 2014 for seven months. Fecal samples were analyzed for intestinal parasites by floatation and sedimentation methods. The intensity of most commonly seen parasites was determined by the McMaster counting technique. In 198 collected fecal samples, six types of parasites were detected, namely Eimeria 89 (44.95%), Ascaris suum 43 (21.72%), Strongyloides sp. 41 (20.71%), Trichocephalus suis 19 (9.60%), Fasciolopsis buski 10 (5.05%), and Fasciola 2 (1.01%). Highest intensities were observed for Eimeria (maximum 80900 oocyst/g), followed by Ascaris suum (2400 egg/g), Strongyloides sp. (1900 egg/g), and Trichocephalus suis (1300 egg/g); the others were reported at much lower intensities. Infection levels and intensities of the parasites tended to be higher during the hot months, June to September. No significant difference between communes was found. At least one type of parasites was present in 137 samples (69.19%). Most of farms (96.67%) were positive for at least one type of parasites in at least one sample. There was a significant difference in infection level of endoparasites between biogas and non-biogas farms. The general high parasite burden reported in this study will be addressed in future interventions which will include parasite control apart from other measures. |
