To distinguish whether the vaccine is suitable for drinking water immunity. Vaccines suitable for drinking water are mostly attenuated vaccines.
The concentration and dose of the vaccine. Poultry of different ages has different maximum drinking water at one time, so the concentration of drinking vaccine is also different. The corresponding vaccine concentration of chickens was 0.2% at 1 week, 0.17% to 0.1% at 2 to 4 weeks, 0.1% to 0.05% at 1 to 2 months, and 0.045% at 3 to 4 months. 0.033%.
Dilution of vaccine water is particular about it. Distilled water is used for immunization of drinking water, but it is also possible to use clean deep well water, and it must not use tap water containing disinfectant or well water that has not been cleaned for a long time.
Do a good job of stopping water before drinking water. Drinking water should be stopped before immunization. In spring and autumn, water is stopped for 4 to 5 hours, during the summer, it is stopped for 2 to 3 hours, and in winter, it is stopped for 5 to 7 hours.
Perform experimental procedures. Large-scale poultry flocks should first be immunized with small groups of drinking water. After a day or so, there is no abnormality, and then a large number of drinking water is immunized.
Use the vaccine correctly. The vaccine must be ready for use, and be prepared in a cool, dark place, and be consumed within 4 to 6 hours. If the vaccine is in a frozen state, it will naturally melt and cannot be roasted, heated, or heated with light.
