| 总结: | The village poultry is an important component of the
poultry industry in South East Asia . However , Newcastle disease
is always a thre at to them . While the disease is usually
adequately control led by repeated applications of suitable
vaccines in commercial poultry , it has not been success fully
controlled in village chickens. A new method of vaccine
production and administration for the village chickens needs
to be developed . The objective of this study was to select an
avirulent Newcastle disease virus which is immunogenic , heat
resistant and transmissible among chickens and to incorporate
the virus in feed that can be offered to chickens .
The vaccine was prepared by coating an immunogenic and
heat tolerant sub strain of V 4 virus onto food pellets . A
nominal chicken do s e o f vaccine was 10 g of pellets containing
10650 % egg infectious doses of vaccine virus. The vaccine was prepared by coating an immunogenic and
