A STUDY ON PREVALENCE OF GASTRO-INTESTINAL PARASITES IN CALF IN PANCHAGAR DISTRICT

Abstract

The prevalence and seasonal variation in gastro-intestinal parasites were studied in native (N = 312) and crossbred (N = 118) calves with four age groups (Up to 3 months, >3 to 6 months and >6 to 9 months and >9 to 12 months) and three seasons (rainy, autumn and winter) in Debiganj Upazila, Panchagar district for a period of July 15 to November15 2009. Among them 180 native & 60 calves were infected. Coproscopic examine were done to detect the worm load in each of the calf. The maximum rate of infection of gastro-intestinal parasite was recorded in native calf with the exception of Trichuris. In the rainy season highest gastro-intestinal parasitic infestation was observed. The infection rates of Fasciola (18.08%), Bunostomum (16.39%), Trichuris (4.47%) and Schistosoma (9.68%) were highest in the age group >9 to12 months and lowest in the age group up to 3 months. The infection rates of Strongylid (6.6%), Strongyloides (7.23%), Trichuris (4.47%) were very high in the age group < 3 to 6 months and low in the age group >o to 3 months. The infection rates of T.vitulorum (43.6%), Strongylid (6.6%), Strongyloides (7.23%) and Schistosoma (9.68%) were very high in the age group < 1 to 3 months and low in the age group >9 to 12 months
