Nobilis Gumboro D78: an effective defence

Trials with recently isolated (2002) pathogenic strains of IBDV demonstrate that Nobilis Gumboro D78 is outstandingly effective:

Protects against bursal damage.
Breaks through higher levels of maternally derived antibodies (MDA) than other widely used intermediate Gumboro vaccines.
Prevents clinical symptoms of Gumboro Disease.

Description

Nobilis Gumboro D78 is a live vaccine against Infectious bursal disease (Gumboro) in chickens.

Composition

Active components per dose:
- Live I.B.D. virus strain D78: ≥ log^4.0 TCID₅₀

Formulation

A freeze-dried pellet.

Target species

Chickens.

Indications

Vaccination of chickens against Infectious Bursal Disease.

Vaccination programme

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.

Dosage

One dose per bird.

Method of administration

Drinking water.
The vaccine should be dissolved in the volume of water which will be consumed by the birds within approx. 2 hours.
Spray method.
The vaccine should be dissolved in water at the rate of 1000 doses per litre. It should be used as a coarse spray evenly over the birds at a distance of 30 to 40 cm.
Intranasal/intraocular instillation.
The vaccine should be dissolved in physiological saline solution (usually 30 ml per 1000 doses) and administered by means of a standardized dropper. One drop should be applied from a height of a few centimeters into one nostril or one eye.

Note: An Intervet oculo/nasal diluent is commercially available in several countries.
