Abstract   

    Formalinized aqua based liver organ vaccines for Angara disease (AD)/hydropericardium-hepatitis syndrome (HHS) are effective for the control of the disease. The experimental formalinized 10, 7.5 and 5% liver organ vaccines showed significant differences in efficacy from 2.5 and 1% liver organ vaccines. However, 10, 7.5 and 5% liver organ vaccines differed non significantly from one another. The vaccines of 10 and 7.5% liver organ concentrations showed the best results in terms of reducing mortality among the given groups, while 5% liver organ vaccine proved the best in both efficacy and economy. The vaccination of AD showed positive effect on the immune response of the chicks against Newcastle disease virus.

Key words: Angara disease, hydropericardium-hepatitis syndrome, efficacy, vaccines
