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 Ascaris, Strongylid, Strongyloids and Moniezia were very high in the age group 36 months.
