Vaccination
Nobilis Gumboro D78 can be administered to birds of 7-28 days of age. Strain D78 is effective in the face of the maternally derived antibody level usually existing in flocks at 7-28 days of age. The optimal time for vaccination depends on the level of the maternally derived antibodies. When there is a very variable antibody level it is advisable to vaccinate the chickens twice with an interval of one week between doses. Nobilis Gumboro D78 can also be safely administered at one day of age to birds with a low level of maternal antibodies, or none at all.

– Drinking water.
The vaccine should be dissolved in the volume of water which will be consumed by the birds within approx. 2 hours.
