A cross-sectional study on Newcastle disease (ND) was conducted in apparently healthy and non- vaccinated village chicken at Alamata district from December 2015 to April 2016. A total of 290 chickens were randomly selected to determine the sero- prevalence and identify possible risk factors for the disease using haemagglutination inhibition (HI) test. The overall sero- prevalence of Newcastle disease in the study area was found to be 26.2% (76/214). A statistically significant difference (x2= 4.627; p= 0.031) in the sero- prevalence between the young and adult chicken were found in the study area. The difference in sero-prevalence between local and cross breed was also statistically significant (x2= 21.799; p= 0.00). However, the difference were statistically insignificant between sexes and flock size (x2= 4.755; p= 0.665 and x2=0.603; p= 0.437) respectively. The high prevalence and no vaccination history indicated that, the chicken populations in the study area have been exposed to the virus sometime in the past. Based on this result the disease affects more likely to young, cross and lowland chickens according to age, breed and altitude respectively. Therefore, further study has to be conducted to know the depth (strength) of the impact of those possible risk factors on epidemiology of this disease.
