Prevalence of Bovine Fasciolosis in major Abattiors of Adamawa State, Nigeria

Cross sectional epidemiologic studies of bovine Fasciolosis was conducted in some selected abattoirs of Adamawa state (Yola, Mubi and Numan) using postmortem examination from liver of slaughtered animals.A total of 3,015 slaughtered cattled were examined at post mortem and 657 (21.8%) liver fluke cases were recorded. The prevalence rate at Yola, Mubi and Numan were 22.08%, 22.34% and 19.92% respectively. The overall sex-specific prevalence rate was significantly higher (P<0.05) in females (23.6%) than in males (18.2%). Age specific prevalence rate was higher (23.3%) in the group that were 49-72 months . Statistical analysis showed no significant difference in prevalence rate among the age groups: there is no association between infection rate and age. The breed specific prevalence was lowest (12.32%) in sokoto gudali and highest (31.2%) in red bororo. Chi-square analysis indicated that there was strong asssociation between infection and breeds. A significant difference (P<0.05) was observed between the prevalence of fasciolosis that occurred in the dry season (25.98%) and that of the rainy season (18.14%). The result shows strong association (P<0.05) between season, sex, and breeds, of cattle and the disease. It was also observed that bovine fasciolosis is an obstacle to livestock production and development in Adamawa state and Nigeria.
