Fig. 2

Geometric mean (log22) ± SE of HI antibody titer of chicken vaccinated by coating on 13 different types of grains in comparison to vaccination via water (positive control) and negative control. Red arrows labeled with V1, V2 and V3 on top indicated the day of vaccination. Maternal antibody at day old was high but reduced at day 14. One time vaccination using different carrier grains induced HI titer differently. Second and third round vaccination (booster) upgraded the induction of HI titer significantly (p< 0.05) but at varying level depending on the types of grain used as vaccine carrier
