The prevention of swine fever should be scientifically immunized,

Appropriately improve the immunotic dose of the vaccine is relatively reasonable.

Recommended swine fever in 35 days old, intramuscular injection of lack of poisonous seedlings in the muscles, and two immobilized seeds in 60-65 days of intramuscular injection.

Admixes, empty moisturous pigs with 4 heads of prodontic injection;

species that the boar is 4 years in March and September in September;

Pregnant mother pigs disabled disabled seedlings.

For blue ear disease, the protected seedlings are much lower than that of the disabled vaccine.

Recommended breast pigs with blue ear to destroy the vast seedlings twice, the first intramuscular injection can be induced by 1 part, and then inoculated with the same vaccine in the same vaccine after 20 days;

Other pigs use a weak poisonous seedlings, and the sows for 70 days of pregnancy are not inoculated. After the delivery is weaned, they will be inoculated; the piglets are immunized once at 3 weeks old and 10 weeks old.
