การสำรวจความชุกพยาธิภายในทางเดินอาหารของโคเนื้อ อำเภอไทรโยค จังหวัดกาญจนบุรี

Abstract

Between March 2010 and February 2012, fecal samples from 309 beef cattle at Sai-Yok district, Kanchanaburi, Thailand were used to determine the prevalence of gastro-intestinal (GI) parasites infection and to examine the associated determinants i.e. sex, age, and management. The overall prevalence of GI parasites was 86.4% (267/309). The important parasites identified were Strongylids 71.84% (222/309), followed by rumen fluke 20.06% (65/309) and Strongyloides papillosus 17.15% (53/309). The protozoan infection of coccidian oocysts (5.5% 17/309) was also observed. Female cattle, cattle older than 3 years, and native cattle showed the higher prevalent rate including those feed in the grazing pasture. This result provides a basal line data of GI parasites infection which can be used for treatment and control strategies against GI parasites in the future.
