• Use only as directed.

A.    Spray Method

The vaccine should be dissolved in cool, clean, non-chlorinated water which is free from iron and chlorine. The vial of freeze-dried vaccine should be opened under water. The spray apparatus should be free from sediments, corrosion and traces of disinfectants (preferably to be used for vaccination purposes only).

The vaccine medicated water should be spread evenly over the correct number of chickens, at a distance of 30 – 40 cm, preferably when the chickens are sitting together in dim light.

For day-old chickens use 0,25 litres of water per 1 000 birds and set nozzle to produce fine droplets, falling like a fine rain. For older chickens, dissolve 1 000 doses per litre of water and set the nozzle to produce fine droplets (Aerosol generators should be used only when this is known to be safe to chickens).

B. Eye Drop Application

Dissolve the vaccine in Diluent Oculo-nasal and administer by means of a standardised dropper (usually 35 mℓ per
1 000 doses). One drop should be applied from a height of a few centimetres onto one eye. As an eye drop application, the drop should be allowed to spread evenly across the surface of the eye.

Do not release the fowl until a swallowing motion is noticed.

For numbers of birds between standard dosages, the next high dosage should be chosen.

Vacination program

The optimum time and method of administration depend largely upon local situation. The advice of a veterinary surgeon should be sought. The vaccine is safe to use from 1 day of age onwards.
