Abstract:
After vaccination of breeding pheasants against Newcastle disease the transmission of antibodies to chicken was investigated by serological methods (hemagglutination inhibition test). The vaccination was carried out about 4 weeks before the start of the laying season. High levels of antibodies were found in egg yolk and blood serum of three days old pheasant chicks. The antibody level dropped at the end of laying season about 10 1/2 weeks after vaccination slightly. Antibodies were found in all of the investigated eggs.
