Evaluation of Antibody Response to Newcastle Disease Vaccination in Chickens in Some Commercial Farms-Ii Two Local Government Areas in Lagos State, Nigeria

Newcastle disease (ND) also known as Ranikhit disease (RD) is a highly contagious viral disease that attacks many species of domestic and wild birds [1]. Several species of birds are affected by ND with chickens and turkeys being readily susceptible. It was reported that more than 250 species of free living and caged birds have been infected with NDV therefore; it is probable that most avian species, domestic and feral, can be infected with strains of NDV [2]. There can be little doubt that the highly pathogenic form of ND is a serious problem, either as an enzootic disease or as a cause of regular, frequent epizootics throughout Africa, Asia, Central America and parts of South America [3-6]. Several outbreaks have been reported in guinea fowls in some African countries such as Nigeria and Niger [7], including Morocco [8]. There was serological evidence of ND infection in pigeons in Nigeria [9].
