1. Correct selection and use of vaccines: the quality of vaccines is the first step to ensure the effectiveness. When selecting vaccines, breeders should pay attention to the selection of high-quality vaccines produced by designated national manufacturers. They should not purchase vaccines without guarantees for the sake of cheap purchase. Otherwise, although the cost is low, the effect is not good. In addition, each epidemic should be checked before vaccination. If the seedling bottle is damaged or not, the seal is tight or not, the vacuum in the bottle and the validity period are not qualified, it can not be used.
2. Establishing reasonable immunization procedures: The key to successful immunization lies in the rationality of immunization procedures. When formulating immunization procedures, farmers should formulate scientific and reasonable immunization procedures according to the epidemic situation and laws of local diseases, as well as the breeds of chickens, age and other factors.
3. Adopt the correct immunization operation method: There are many ways to immunize, depending on the situation of the farmers. When immunizing with drinking water, the farmers need to pay attention to not using metal containers. The vaccine water immunized with drinking water must use boiled water or distilled water, and there must be no disinfectant or metal ions in the water. In addition, the immunization with drinking water should ensure that the vaccine is consumed within one hour. If farmers use aerosol immunization, then they can not use saline to dilute the vaccine and ensure that the aerosol particles are about 50 microns. During eye-dropping and nose-dropping immunization, farmers should pay attention to ensuring that the vaccine enters the eyes and nasal cavity. The needle-seed vaccine must be pricked and dipped in order to ensure that the needle can be immersed in the vaccine solution every time. When the aquaculture users are vaccinated with continuous syringes, the injection dose should be corrected repeatedly, so that the error is less than 0.01 ml, and the needle should not be too thick, so as to avoid the outflow of the vaccine after needle extraction.
4. Establish and improve the epidemic prevention system: If there is an epidemic situation in the farmer's area, chickens without disease can be vaccinated urgently under strict disinfection conditions, and then feed should be monitored to ensure that there are no mycotoxins and other chemicals. Strengthen feeding management, reduce stress and the occurrence of various diseases, rational selection of immune enhancers. The stress of chickens should be minimized within 24 hours before and after immunization. Appropriate increase of methionine, valine, vitamin A, vitamin B, vitamin C, vitamin D, etc., to ensure immunity. At the same time, levamisole, BCG, interferon and other immune enhancers can be rationally selected to enhance the immune effect.
