Abstract
Background: Infectious bursal disease (IBD) is a highly contagious viral disease challenging poultry industry throughout the world. It is also among the main obstacles in the different chicken production system in Ethiopia. This study was conducted with the aim of determining seroprevalence and associated risk factors of IBD in backyard and intensively managed chickens of the study area.
Methods: A cross-sectional study was conducted in selected districts of western Oromia on intensive and backyard production systems to investigate seroprevalence of IBD and associated risk factors from September 2020 to August 2021. A total of 384 chickens of either sex, 128 from each district, were included from three randomly selected peasant associations (PAs). In addition, 180 individual poultry keepers, of both sexes, and different educational backgrounds, were included for questionnaire survey (Supplementary Material). Data were analyzed using SPSS Version-20, and results were presented as percentages. The samples were processed by using (ProFLOKIBV, USA) indirect enzyme-linked immunosorbent assay (I-ELISA) kits.
Results: Out of 384 serum samples tested, 66.93% (n = 257) were found positive by indirect ELISA. The highest prevalence was recorded from Sasiga district Balo Bareda PA. Prevalence of IBD showed significant statistical association (p < 0.05) among owner education level, chicken rearing practice, origin and breed. Questionnaire survey results showed the majority of respondents lack sufficient knowledge about IBD and other chicken diseases. The practice of backyard chicken producers on vaccination and treatment of sick birds is limited.
Conclusion: In conclusion, IBD is a major factor hindering production and health of birds. Proper vaccination programs coordinated with awareness creation of chicken owners on how to isolate and treat sick birds should be implemented.
