Incidence of Liver Flukes and Gastro-Intestinal Parasites in Cattle

Abstract

The prevalence and seasonal variation in liver fluke and gastro-intestinal parasites were studied in native (n = 360) and crossbred (n = 360) cattle with four age groups ( < 12 months, >12-24 months, >24-36 months and >36 months) and three seasons (summer, rainy and winter) in Trishal Upazilla, Mymensingh district for a period of November 2002 to October 2003. Feces were collected to examine the worm load in each of the animal. The maximum rate of infection of gastro-intestinal parasite was recorded in crossbred cattle with the exception of Strongylid. In the rainy season highest gastro-intestinal parasitic infestation was observed. The infection rates of Fasciola, Paramphistomum, Trichuris and Schistosoma were highest in the age group >36 months and lowest in the age group < 12 months. The infection rates of Ascaris, Strongylid, Strongyloids and Moniezia were very high in the age group < 12 months and low in the age group >36 months.
