This study was carried out in Bulyansiime village, Iganga District. A baseline survey was conducted to determine the serological status and flock dynamics of the free range chicken. This was followed by vaccination of all birds above 2 weeks and sera collection from adult birds after every 3 months for a period of 9 months. Haemagglutination Inhibition tests were performed to determine the level of antibody titers against New Castle Disease Virus. Flock production data per household was recorded alongside the vaccination and sera collection exercise. Results derived were compared to the baseline data collected. The percentage of adult flock with serum antibody titres above protection level of log23 increased from 32% pre-vaccination to 100% at the 9th month post-vaccination. An increase in flock size from 10.83±9.25 to 20.11±15.20 birds per household after 9 months birds was observed.
