Duration of immunity: 16 weeks
Dose to be administered and administration route
Vaccination scheme:
Broilers: vaccination from first day of life.
Future layers or breeders: vaccination from first day of life or during the 3rd to 4th week of life for immediate protection of young chickens and priming for subsequent vaccinations with an inactivated vaccine. Layer or breeders: vaccination from onset of lay.
One dose of vaccine per bird administered by spray administration, eye drop administration or drinking water administration. The amount of water to be used depends on the method of administration:
For spray administration: Dilute and administer the reconstituted vaccine at a rate of one dose of reconstituted vaccine per bird, according to the directions of your specific coarse spray vaccination equipment. Recommended volume for one dose is between 0.1 and 0.5 ml.
The spray device used must be set to a droplet size of 0.12 to 0.15 mm in diameter. The distance from the spray head to the bird should be approximately 50 cm.
During spraying and for about 20 - 30 minutes thereafter, ventilation should be switched off or reduced. Dimming light sources is recommended to avoid unsettling the animals.
For eye drop administration: 50 ml per 1000 birds.
One drop (0.05 ml) of the vaccine solution is administered into an eye. In doing so, the head of the animal must be fixed so that the drop does not run down. 1000 doses of the vaccine are dissolved in 50 ml water.
For drinking water administration: Depending on the age of the birds: The amount of water in litres per 1000 chickens should be set according to the age of the chickens in days (up to a maximum of 40 litres).
Water containing a high level of chlorine or metal ions should not be used and conduit pipes, tubing, etc. should be thoroughly clean and free of traces of disinfectants and detergents. It is recommended to add protective proteins in the form of skimmed milk powder (2 g per litre of water) or skimmed milk (1 litre per 50 litres of water) to the water.
The birds should be deprived from water about 2 hours before vaccination. For vaccination, use as many litres of water as the age of the birds in days, per 1000 birds, up to a maximum of 40 litres as indicated above.
Prepare the amount of vaccine to be used within 2 hours. Remove the sealing cap and stopper from the vaccine vial and suspend the vaccine in the corresponding amount of water and mix carefully. Care should be taken to empty the ampoule completely and administer the diluted vaccine immediately.
Make sure that birds do not have access to untreated water until the treated water has been consumed.
One day before and after vaccination no drugs or disinfectants should be applied to the chickens.
Adverse reactions
In very rare cases, a slight reaction to vaccination can be observed in the form of transient, mild respiratory symptoms.
The frequency of adverse reactions is defined using the following convention: - very common (more than 1 in 10 animals treated displaying adverse reaction(s))
- common (more than 1 but less than 10 animals in 100 animals treated)
- uncommon (more than 1 but less than 10 animals in 1,000 animals treated)
- rare (more than 1 but less than 10 animals in 10,000 animals treated) - very rare (less than 1 animal in 10,000 animals treated, including isolated reports).
