SURVEY FOR BRUCELLA ANTIBODIES IN GOATS AND FARMERS’ KNOWLEDGE AND PRACTICES TOWARDS BRUCELLOSIS IN GIWA LOCAL GOVERNMENT AREA OF KADUNA STATE, NIGERIA
Abstract:
Brucellosis is a zoonotic disease that results in great economic losses to farmers due to abortion and infertility leading to low productivity. To determine the prevalence of Brucella antibodies in Giwa Local Government Area of Kaduna State, 280 serum and 113 milk samples were collected from goats in six Districts. Rose Bengal Plate Test (RBPT), Competitive ELISA (cELISA) and Milk Ring Test (MRT) were used to detect Brucella antibodies in the samples. Out of the 280 sera, 23 (8.2%) and 7 (2.5%) were positive for Brucella antibodies by RBPT and cELISA respectively; while out of the 113 milk samples, 43 (38.1%) were positive for Brucella antibodies. Females had higher prevalence (8.3%) than the males (8.0%), West African Dwarf and Kano brown breeds had the highest positive reactors (12.5% each) than the red Sokoto (7.8%) breed, while goats above 36 months of age showed higher rate of Brucella antibodies than the younger goats sampled. There was no statistically significant associations between breed, sex and age of the goats sampled and prevalence of Brucella antibodies (P>0.337), but there was a significant association (P<0.037) between location of sample collection and prevalence of Brucella antibodies in milk. Forty-one questionnaires were used to assess farmers’ knowledge on Brucella infection and their practices. The prevalence of Brucella antibodies was high (10.9%) in goats from households where the farmers had no knowledge of the disease than those who had knowledge of the disease (5.9%). Those with abortion history had a lower prevalence (6.3%) as compared to those without incidence of abortion in their flock (12.5%). Detection of Brucella antibodies was highest (13.8%) in flocks that recorded abortion during the late gestation period than the early (5.0%) and mid (12.3%) gestation periods. The association between the prevalence of Brucella antibodies and farmers’ knowledge of the disease, source of goats, abortion history and cases of retained placenta was not statistically significant (P>0.05).
