| description | Poultry production contributes significantly to the livelihoods of Ethiopian farmers and the national economy, although it is hampered by different factors, including infectious diseases. A cross-sectional study was conducted from December 2019 to May 2020 in Melokoza District, Gofa Zone, Ethiopia. The objectives of the study were to estimate the seroprevalence of Newcastle disease in unvaccinated chickens and to identify the risk factors associated with the disease. A systematic random sampling technique was employed to select chickens from individual chicken owners. A total of 405 blood samples were collected and submitted to the national veterinary institute in Bishoftu, Ethiopia. Hemaglutination inhibition test was performed to detect antibodies from the collected chickens’ serum. Both univariable and multivariable logistic regression analyses were performed by using the STATA statistical software package. The test result showed that the overall seroprevalence was 68.8% (95% CI: 64%, 73%). The highest seroprevalence of 86% (58/67) was recorded in Gazar kebele (lowland), whereas the lowest seroprevalence of 45% (32/71) was recorded in Maizelo (highland). Sex, age, altitude and management practice risk factors showed significant associations (p < 0.05) with the disease prevalence. In conclusion, this study emphasized the prevailing higher prevalence of Newcastle disease in free-scavenging chickens. Regular vaccination for Newcastle disease is therefore recommended. Further studies are warranted to better understand the circulating strain and its economic effect on backyard poultry production in the study area. |
