Gel-Pac® Improves the Titer of Live Infectious Bronchitis (IB) Vaccine for Poultry Hatcheries

Live IB vaccines were originally developed and delivered by nose drop to poultry because, logically, the respiratory tract was the tissue we were trying to protect by a mucosal response. However, eventually the economic pressure from high labor costs in developed poultry markets forced researchers to seek more cost effective ways to deliver live virus vaccine and protect poultry. During the 1950’s the IB vaccine strains were confirmed as being viscero-active, meaning they are able to provide immunity and protect the respiratory tract from disease challenges even if they are swallowed, not inhaled. From that point IB vaccines have been mass applied via both hatchery aerosol spray and drinking water. Dosing by spray at day-of hatch is still favored over dosing by drinking water after placement because, among other things, earlier application provides earlier onset of immunity.



New generation stabilizers improve Newcastle Disease vaccine performance

Ryan-article-photoAsian poultry integrators increasingly rely on hatcheries to administer important vaccines. Pressure to adopt earlier vaccination strategies include injected, sprayed and in ovo programs, each method and antigen imposing its own particular burden application and risk of failure. ZHANG JIANG, VERGIL DAVIS and RYAN IZARD* discuss the potential of new generation stabilizer technologies to protect fragile Newcastle Disease (ND) vaccines from the harmful effects of chlorine. This can allow producers to use ordinary tap water or well water to make spray vaccination more convenient and efficient.
