    abstract = {A cross sectional study was conducted on 384 chicken raised 
  under traditional management system in four villages of Bishoftu area using 
  Haemagglutination Inhibition (HI) test for the detection of antibodies against 
  Newcastle Disease (ND) virus in serum samples collected from chickens with no 
  history of vaccination and apparently healthy during December 2011 to April 
  2012. An overall sero-positive rate of 23.4% was recorded in this study. The 
  differences in sero-prevalence however, were not significant (p>0.05) among 
  village, sex, age, flock size, feeding system, source of chicken and contact 
  with wild birds. However, housing system had a significant difference (p<0.05) 
  on sero-prevalence rate of the disease. The fact that most of the chicken originated 
  from village had low HI titer (about 54.4%, &le;2 log<SUB>2</SUB>) warrant the 
  need to systematic consideration for disease prevention strategy in the village 
  chicken. Detailed further study on ND virus strain identification, a survey 
  of major poultry diseases and improved management packages should be devised.}
