To determine the prevalence of ectoparasitic infestation in goat at Gazipur district in Bangladesh, an epidemiological study was carried out during the period from November 2008 to October 2009. Among 165 Black Bengal goats examined, 114 (69.09%) were found to be infested with several species of ticks, lice and flea. The prevalence rate was highest in Boophilus microplus (45.45%) followed by Rhipicephalus sanguineus (31.51%), Linognathus vituli (25.45%), Heamaphysalis bispinosa (20%), Haematopinus eurysternus (15.75%), Damalinia caprae (8.48%) and Ctenocephalides canis (4.84%). In this study, prevalence of ectoparasitic infestation in relation to age, sex, nutritional condition and rearing systems of animals and seasons of the year, were also observed. Young goats aged ≤ 6 months (75.86%) were more susceptible than adults aged > 6-24 months (65.51%) and older goats > 24 months (59.32%). In female, prevalence was recorded significantly (p < 0.05) higher than male. Animal with poor health was found to be significantly more vulnerable to such parasitic infestation than normal healthy animals. Prevalence of ectoparasites was significantly (p<0.05) higher in animals, reared under free-range system than that of semi-intensive system. Prevalence was highest (p<0.05) in the summer (81.35%) followed by winter (62.96%) and rainy season (59.26%). Mean parasitic burden was 1.60±0.12 per square inches of heavily infected area in goats. The present study showed that ectoparasitic species were abundant and prevalence and density of infection was very high that deserves immediate intervention measures to reduce the risk of transmission.
