Sera obtained from forty (40) chickens per LGA during pre-vaccination, post-vaccination and post-booster vaccination with NDV4 thermostable vaccine were subjected to Hemagglutination Inhibition (HI) test.
Result: Antibody detection showed seroconversion in chickens 28day post vaccination and post booster vaccination with significant (P
