From the study it was evident that prevalence of gastrointestinal helminths in Black Bengal goats was very
high (94.67%) (Table 1). Similar experiments were conducted by earlier scientists in different breeds of goats in
various countries. Hassan (1964) reported that 82.1% goats were positive for helminth infections whereas Patel
et al. (2001) recorded 54.92% gastrointestinal helminth infection in goats in India. However, this variation in
between the present and earlier results might be due to the differences among the geographical locations and
climatic conditions of the experimental areas, method of study, sample size, breed of the animals. Bangladesh is
a tropical country with moderate winter and summer. This climatic condition is suitable for the development and
survival of many parasites. Besides, in this country most of the goats are reared in rural areas in scavenging or
semi scavenging system (Devendra, 1970). In this type of rearing, goats graze on the fields. Probably, this type
of management practice plays a vital role in the high rate of parasitic infection.
