Study on infection of Fasciolopsis buski in local pigs in Dien Bien province

Abstract

In order to obtain data on the situation of infection with Fasciolopsis buski fluke in the local pigs in Dien Bien province, this study was conducted from 2016 to 2019 through the examination of 1872 pig fecal samples and autopsy of 1163 pigs. The studied results showed that the infection rate of local pigs with Fasciolopsis buski was 2.75% through the autopsy and 2.56% through examining fecal samples. This infection rate was fluctuated by locality from 1.04% to 4.12%. The pig age, raising procedures, season that effected to the prevalence of Fasciolopsis buski in the local pigs (P<0,05). The infection rate and intensity of Fasciolopsis buski increased by the age of pigs. The infection rate of local pigs with Fasciolopsis buski in the summer and autumn season was higher than in the winter and spring season. The infection rate of pigs with Fasciolopsis buski fluke was highest in the free grazing method (3.66%) and the lowest infection rate was in the captive grazing method (0.55%). The pigs raising in the flat area were infected with the higher infection rate (5.96%) in comparison with the pigs raising in the high mountain area (0.86%).
