Hygiene management and vaccination of breeding hens in Japan: Protection of chicks with maternally derived antibodies induced by vaccines
2017
Vaccination of breeding hens is expected to protect both breeding hens themselves as well as progeny chicks by inducing maternally derived disease-specific antibodies (MDA). However, the efficacy of live vaccines is affected by levels of MDA. Thus, information on antibody titers and their dispersions is useful for establishing vaccination programs. This commentary overviews information on the latest findings on the vaccines and MDA against the diseases that involve MDA and the following infectious diseases to aid in disease control of breeding hens and commercial chicks: Newcastle disease, infectious bronchitis, Marek's disease, infectious bursal disease, fowl pox, avian encephalomyelitis, avian reovirus infection, chicken anemia virus infection, and colibacillosis.
