A sero-epidemiological survey of antibody to Newcastle disease (ND) virus was conducted in the unvaccinated local chickens in Yewa division of Ogun State, Nigeria using haemagglutination inhibition (HI) test. All the 180 sera samples collected tested positive for ND antibody. The range of HI antibody titre was 23 to 27. Out of the 180 chicks tested, 44 (24.4%) had HI antibody titre of 23; the remaining birds (75.6%) had higher titres of up to 27. The results showed the high endemicity of the disease among the local chicken population in the survey area in Nigeria.
