Item Seroprevalence of Newcastle disease in indigenous chickens in Ilorin, Kwara State, Nigeria(Faculty of Veterinary Medicine, Usmanu Danfodio University, Sokoto, Sokoto Stata, Nigeria, 2022-09) Olorunshola I.D.; Daodu O.B.; Ogunyemi M.; Folahan F.; Omoregie S.; Ogah J.I.Newcastle disease (ND) is a disease of high economic importance to poultry farmers in Nigeria. Its impact on poultry include illness of poultry, reduction in egg production, immunosuppression, and death. This study was carried out to determine the prevalence of Newcastle disease in indigenous (local) chickens from 2 poultry abattoirs in the Ilorin metropolis. A total of 400 blood samples were aseptically collected in plain bottles from the jugular veins of local chickens at slaughter using exsanguination and transported to the laboratory in batches. Sera samples were harvested from the blood by centrifugation at 3000 rpm for 10 minutes, after which they were stored at -20oC before serological assay. The sera were subjected to Haemagglutination Inhibition (HI) test to check for the presence of Newcastle disease virus (NDV) antibody following a standard procedure with titer values for each sample recorded. The geometric mean of the HI antibody titer (GMT) and the percentages of detectable NDV HI antibody titer werecalculated using descriptive statistics. Of the 400 serum samples examined, 53 (13.25%) were positive for ND antibodies, with titre value ≥ 1:16. The location from which the birds were selected had no significant relationship with the prevalence of ND antibodies as both Oja tuntun (11.9%), and Ipata market (14.6%) had a closely similar prevalence of antibodies (p > 0.05). The feather arrangement of birds did not also have any significant impact on the prevalence of antibodies (p > 0.05). However, in this study, we observed a higher prevalence of antibodies among hens (14.7%) than in cocks (12.5%) or growers (8.9%). The high prevalence of ND antibodies in indigenous chickens in the study area showed the endemicity of the disease in the study areas. With most of the chickens are not vaccinated amid non-compliance to vaccine administration for local chickens. There is a need for poultry farmers in the study location to be educated on the importance of vaccinating poultry birds against ND.
