Formulation
A freeze-dried pellet.
Indications
Immunization of chickens against Gumboro Disease (IBD).
Vaccination
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 chickens can be successfully vaccinated depends on the level of maternally derived antibodies (MDA) and therefore on the type of birds and on the way the parent breeding flock is vaccinated.
Dosage
One dose per bird.
Method of administration
Via the drinking water.
