DIRECTIONS FOR USE – USE ONLY AS DIRECTED
ADMINISTRATION
The vaccine is administered through the drinking water at 1 dose per chicken.
The vaccine should be dissolved in an amount of water, which will be consumed by the chickens within 2 hours.
VACCINATION PROGRAMME
The vaccine virus strain 228E is a less attenuated intermediate IBDV strain. As a result of this, the virus is capable of breaking through the maternal immunity at an earlier stage and will spread better through the vaccinated flock.
The age at which the chickens can be successfully vaccinated depends on the level of maternally derived antibodies (MDA) and therefore on the type of flock and on the way the parent flock had been vaccinated.
The optimum time and method of administration depends largely upon the local situation. Therefore, the advice of a veterinary surgeon should be sought.
IMMUNITY
The first signs of the antibody response are observed 1 week after vaccination.
