Abstract
Aim: This study aimed to assess the level of awareness of rural poultry farmers on vaccination and to detect Newcastle
disease virus (NDV) antibody in local birds (LB) and eggs in Kwara State, Nigeria.
Materials and Methods: Data on farmers’ attitude, knowledge, practices, and experiences on ND mortality were obtained
through an interview using a structured cross-sectional checklist. NDV antibodies were detected in sera and egg yolks of
local chickens (LC) and guinea fowls (GF) using hemagglutination inhibition test.
Results: A total of 83 interviewees, 287 sera and 121 egg yolk extracts, were examined. The study revealed that 98.8%
(82/83) of the interviewee had never vaccinated their flock before. 90% of the interviewee had reported high mortality
in birds within 1-6 months old, while the major clinical signs were cold (40.4%) and torticollis (30.8%). Evidences of
LB exposure to wild-type NDV were confirmed by the detection of NDV antibodies in 20.8% and 0% of LC and GF,
respectively. The mortality differences experienced in <1 and 1-6 months old LB could be explained by the presence of
maternally-derived NDV antibody (49.6%) in egg yolk.
Conclusion: The study showed that LB suffers from NDV as a result of LB keepers’ ignorance and neglect by the government.
This has limited local investment and subsequent contribution to gross domestic product. This study suggests that the key
factors to the prevention of ND remain awareness creation about poultry vaccination, production of affordable vaccines, and
availability/accessibility to veterinarian (or trained personnel).
