Coarse spray vaccination from one day of age.
Coarse Spray
This vaccine has been used in most types of spray equipment, hand-sprayers (e.g. ASL Polyspray 2), knapsack sprayers (e.g. Birchmeyer with 0.55 or 1.6 mm spray nozzle, Gloria with 1.0 mm nozzle) or automatic spraying equipment (e.g. Bimex). The apparatus should be set to deliver a coarse spray (droplet size of 80-160 micrometres), allowing a dose of 0.5 ml per bird.
The lyophilised vaccine should be reconstituted with water of good quality at room temperature e.g. deionised water or good quality drinking water.
The lyophilised vaccine should be reconstituted as follows:
Remove the aluminium cap from the vial. To reconstitute the lyophilised vaccine, the rubber stopper should be removed whilst the vial is immersed in a plastic measuring jug containing 0.5 litre of clean cool water.
Half fill the vial with water, replace the stopper and shake to remove any remnants in the vial.
The content of the vial should then be added to the water in the jug, mixed well and transferred to the sprayer tank and thoroughly mixed.
For the 5,000 dose vial a total amount of 2.5 L water is required and for the 10,000 dose vial a total amount of 5 L water should be used.
The chickens should be sprayed in chick boxes or brooding rings in the house to avoid loss of vaccine virus.
