Immunity response To Inactivated and live infectious bursal disease vaccines. The vaccination with inactivated oil emulsion IBDV vaccine which was tested in breeder chickens proved to be effective, since it developed high levels of precipitating antibodies. The progeny chicks vaccinated with a live IBDV vaccine at 10 days of age neither accelerated the maternal antibody depletion rate nor presented a stronger resistance against the challenge in comparison with non vaccinated birds.

Abstract
Immunity response To Inactivated and live infectious bursal disease vaccines. The vaccination with inactivated oil emulsion IBDV vaccine which was tested in breeder chickens proved to be effective, since it developed high levels of precipitating antibodies. The progeny chicks vaccinated with a live IBDV vaccine at 10 days of age neither accelerated the maternal antibody depletion rate nor presented a stronger resistance against the challenge in comparison with non vaccinated birds.File in questo prodotto:
