Newcastle Disease Vaccination Programs for Broilers, Layers and Meat Breeder Chickens
نویسندگان
چکیده
All Australian states currently (or will shortly in 2005), require commercial poultry to follow mandatory vaccination programs as described in a set of Standard Operating Procedures (SOPs) developed by the Newcastle Disease (ND) Management Group (NDMG) and endorsed by the respective state government authorities. Those states that previously adopted the SOPs in 2003 allowed a transition period for ND vaccination during which time live ND V4 vaccination could be administered to existing flocks prior to the use of a live plus inactivated (killed) ND vaccination program for new layer and breeder flocks.

Bilateral effects of vaccination against infectious bursal disease and Newcastle disease in specific-pathogen-free layers and commercial broiler chickens.
Different infectious bursal disease virus (IBDV) live vaccines (intermediate, intermediate plus) were compared for their immunosuppressive abilities in specific-pathogen-free (SPF) layer-type chickens or commercial broilers. The Newcastle disease virus (NDV) vaccination model was applied to determine not only IBDV-induced immunosuppression but also bilateral effects between IBDV and NDV. None o...
