Abstract
Newcastle disease constitutes a major constraint to the rural poultry production system in Nigeria. This study was carried out to investigate the seroprevalence of Newcastle disease virus (NDV) in local chickens from Sokoto live bird market, Sokoto, Nigeria, through antibody detection using Competitive Enzyme Linked Immunosorbent Assay (cELISA). An overall seroprevalence rate of 14.72% (34/231) was recorded in this study. Comparison was made between the seroprevalence in sexes and between ages (p>0.05). Female birds had higher prevalence (15.32%) compared to males (14.02%). Higher prevalence was recorded in young chicks (18.75%) and least in adults (13.66%) p >0.05. The study indicated that Newcastle disease is present amongst the population, and sex and age of the birds had no significant influence on the seroprevalence of NDV in the study area. Hence, there should be an improvement in vaccination campaign against Newcastle disease in local chickens.
