Key points that determine the success of vaccination with a spray method
-
Only feed a healthy bird
-
Ensure that the equipment and supplies intended for vaccination are clean and free of disinfectants
-
Monitor the droplet size and spray volume per time unit
-
The generators used (sprays) must be corrosion-resistant, any design that produces monodisperse particles with a diameter of 150-250 μm
-
Test your device, designed to create a spray, filling it with distilled water and using water-sensitive paper. This makes it possible to verify that all particles of the spray have the same value. For the same purpose, you can spray a dark wall or a light concrete floor with a spray
-
Prepare in advance a plan for vaccinating the bird with a spray method, canceling the way in which you will move through the house during this procedure
-
When carrying out the vaccination with a spray-method for the first time, it is advisable to fill the spray with a solution of water rather than a solution of the vaccine. This approach makes it possible to select the optimal spray consumption and the route for the poultry during the procedure
-
Check when it is necessary, whether the batteries of the equipment used are fully charged
-
Pull the electrical cable along the route of your movement to the poultry house during the vaccination (when necessary)
-
Calculate the amount of water required for vaccination
-
Check that the sprayer nozzle is not clogged
-
Ideally, it is best to use distilled water (free of chlorine, metal ions). It is more preferable to use water with a pH in the range of 6.5 to 7.5. Water should be at room temperature (20-22 ° C)
-
Open the vial of the vaccine, fill it up to 1/2 of the volume, cover with a rubber stopper and shake until the drug dissolves completely. Pour the contents into a container with water, where it is planned to prepare a solution for vaccination. Rinse the vial several times so that no vaccine remains in it.
Vaccination of poultry (broilers and chickens) with its floor contents
-
Increase the intensity of room lighting in order to increase bird activity
-
Stimulate the churning of birds into groups, passing along the premises and creating noise. With the same purpose, you can lower the temperature in the room by 1-2 degrees
