A study for bovine brucellosis was conducted using serology to determine the status of the disease in slaughtered cattle. Three hundred and twenty (320) sera were collected from Gusau ModernAbattoir, Zamfara State. The sera were tested using Enzyme Linked Immunosorbent Assay obtained from Veterinary LaboratoryAgencies, Weybridge, UK. An overall prevalence of 20% (64 positive) was obtained with sex prevalence for males and females being10.62% (34 positive) and 9.37% (30 positive) respectively out of 180 males and 140 females tested without significant association (P <0.05). On age distribution, higher prevalence of 11.87% was recorded in age group > 24 months while; lower prevalence of 3.13% was recorded in age group < 12 months. There was no significant association statistically between age and occurrence of antibodies. White Fulani breed had the highest prevalence of 8.75%. There was significant association statistically (p < 0.05) between breed and infection
