Problems that should be paid attention to in pig immune injection

With the strengthening of the publicity, promotion, and service work of animal husbandry departments, farmers' scientific awareness and production skills have also been improved, and almost everyone knows the important truths such as "prevention is more important than cure" and "prevention before it happens." but something a little more detailed and deeper, due to many reasons, some farmers may not understand. Here we talk about several problems that should be paid attention to in pig immunization.

1. Before vaccination, we should study the market and law of local pig disease, and determine the types of diseases to be prevented by immunization.

Second, pay attention to the injection volume of the vaccine: too much injection causes the vaccine reaction, too little antigen is insufficient, can not achieve the preventive effect.

Third, we should pay attention to the timeliness of the vaccine: when using the vaccine, we should choose the vaccine that is preserved according to the requirements and has not reached the expiration period.

Fourth, pregnant sows should not be vaccinated. The vaccine is a weak virus that can cause miscarriage, premature birth or stillbirth in sows.

Fifth, it is not appropriate to vaccinate piglets prematurely. Newborn piglets have maternal antibodies that can effectively fight disease. Early vaccination interferes with maternal antibodies.

Sick pigs cannot be vaccinated.

Try not to inject several vaccines at the same time. Vaccines interfere with each other, affecting the formation of antibodies. Shao Kui
