Field trials were used to assess the efficacy of an inactivated vaccine against the hydropericardium syndrome (Angara disease) in broiler chickens. A single vaccination at 10 to 12 days old was effective for the control of the syndrome; mortality in the vaccinated birds was 0.52% compared with 5.34% in unvaccinated birds kept at the same premises. Vaccination was also effective when carried out in the face of an outbreak; mortality in the vaccinated infected birds was 2.33% compared with 10.27% in unvaccinated infected birds. The results indicate that a formolized vaccine prepared from the liver of experimentally infected birds could be used for the control of the hydropericardium syndrome.
