PREVALENCE OF GASTROINTESTINAL PARASITISM OF BLACK BENGAL GOAT IN CHITTAGONG, BANGLADESH

Abstract

A six month long (August’2011 to January’2012) prevalence study on gastrointestinal parasitism of Black Bengal goat was conducted at two different thanas of Chittagong district, Bangladesh. A total of 150 fecal samples were collected randomly from different households of the representative thanas. Samples were examined by routine coproscopical methods. The investigation revealed that the overall prevalence of gastrointestinal parasitic infections was 31.64% in the study population. Among different gastrointestinal parasitic infections, prevalence of Paramphistomum spp infection was the highest (10.0%) followed by Fasciola spp infection (5.33%). The lowest parasitic infection (0.66%) was recorded in Ostertagia spp and Haemonchus spp infection. Age specific prevalence revealed that older goats were affected more by different gastrointestinal parasitic infections where Paramphistomum spp infection (13.11%) and Fasciola spp infections (8.19%) were the highest in age group III (>2years of age). However, sex specific prevalence exposed that female goat showed more susceptibility to different gastrointestinal parasitic infections. Occurrence of Paramphistomum spp infections was the highest (14.28%) in male Black Bengal goat where as Fasciola spp infections (4.76%) were more in female but it was not statistically significant. It could be stated that the current investigation was a limited study where breed and topographical variation, seasonal pattern of the diseases were not included. Hence, it is suggested further extensive investigation on gastrointestinal parasitism to overcome the limitation of the current study which will assist to determine the important predictors related to such parasitic diseases.
