a Antibody titers in vaccinated and unvaccinated pullets during rearing. Arrows indicate the timing of vaccine administration. At each sampling point, blood (n = 15 each from vaccinated and unvaccinated groups) from jugular vein was collected. Data was analysed by ANOVA. No significant differences were detected between vaccinated and unvaccinated group at week 4 and 8. At week 13, antibody titers in vaccinated flock was significantly higher (p < 0.01) compared to unvaccinated flock (b) Antibody titers in vaccinated and unvaccinated hens during early lay. At each sampling point, blood (n = 10 each from vaccinated and unvaccinated groups) from jugular vein was collected. Data was analysed by ANOVA. Antibody titers in vaccinated flock were significantly higher (p < 0.0001) compared to unvaccinated flock
