A Survey on Prevalence of Gastrointestinal Parasitic Infection in Cattle of Sylhet Division in Bangladesh

A survey was conducted to determine the prevalence of gastrointestinal parasitism in crossbred and local cattle, Sylhet division, Bangladesh. Fecal samples were collected randomly from 288 local and 144 crossbred cattle of four representative areas in three following seasons. The effects of season and age were tested in both local and crossbred cattle. Frequency of trematodes and nematodes infections was constant in all the survey areas. Incident of gastrointestinal parasitic infections was more frequent in rainy season followed by summer and winter. Significantly higher prevalence of Paramphistomum spp (20.53%) was found in rainy season whereas Haemonchus spp (5.46%) and Moniezia spp (4.18%) were higher in summer (P<0.05). Paramphistomum spp infections were more recurrent in adult while Toxocara spp were largest in calf (P<0.05). Prevalence of Haemonchus spp (4.56%) infections was significantly higher in local adult cattle where as Trichostrongylus spp (4.41%) infections were largest in local young cattle (P<0.05). It could be stated that season, age were the significant forecaster of gastrointestinal parasitism. It is highest during rainy season followed by cool, cold and hot season.
