What issues should be noted in pig immunization injections?

As the animal husbandry departments strengthen their publicity, promotion and service work, farmers' scientific awareness and production skills have also improved. Almost everyone now knows important principles such as "prevention is more important than treatment" and "prevention is better than cure," but due to various reasons, some farmers may not understand more detailed and in-depth matters. Here we discuss several issues that should be noted in pig immunization injections.

1. Before immunization, research should be conducted on the epidemic situation and patterns of local pig diseases to determine the types of diseases to be immunized against.

2. Pay attention to the vaccine injection dose: too much injection causes vaccine reactions, while too little provides insufficient antigen and fails to achieve the preventive effect.

3. Pay attention to the timeliness of the vaccine: when using vaccines, select those stored according to requirements and not past their expiration date.

4. Pregnant sows should not be injected with vaccines. Vaccines are a type of attenuated virus that can cause miscarriage, premature birth or stillbirth in sows.

5. Do not inject piglets with vaccines too early. Newborn piglets have maternal antibodies that can effectively fight against diseases. Injecting vaccines too early will interfere with maternal antibodies.

6. Diseased pigs should not be injected with vaccines.

7. Try not to inject several vaccines at the same time. Vaccines will interfere with each other and affect antibody formation. Shao Xi
