(1) Vaccination: Areas, pig farms and pig farms with conditions can adopt the means of swine fever immunization monitoring, and carry out timely immunization according to the fluctuation law of antibody level of swine fever. Indirect hemagglutination test of classical swine fever or enzyme-linked immunosorbent assay can be used to monitor immune titer. If there is no condition for antibody monitoring, two immunization procedures can be adopted according to whether there is sporadic swine fever in this area: a. In areas and farms where there is sporadic swine fever, the piglets are immunized with swine fever vaccine before eating colostrum, and each piglet is injected with 1 dose. B. In areas and farms where the prevention and control of classical swine fever is good and there is no sporadic classical swine fever, the classical swine fever vaccine can be immunized once at the age of 20 days and 60 days respectively. Reserve breeding pigs should be injected again at the age of 6 months. Breeding pigs are injected with swine fever vaccine twice a year. In the process of immunization, the vaccine dosage should be sufficient, the needle length should be appropriate, and flying needles should not be used to ensure the immune effect.
(2) Quarantine and purification: regularly monitor blood samples of breeding pigs, detect and eliminate pigs with virulent antibodies to classical swine fever and pigs with repeated immunosuppression, purify pigs and eliminate hidden dangers of classical swine fever.
(3) Strengthen vaccine management: purchase vaccines from major channels. The vaccine has been diluted, so use it now. When injecting, the vaccine should not leave the ice bucket, and the bucket should not leave the ice to ensure the effectiveness of the vaccine. It is strictly forbidden to use expired vaccines and deformed empty vaccines.
(4) Strengthen the disinfection of needles, needles and injection sites used for immunization to reduce the spread of man-made diseases.
(5) Emergency vaccination: Emergency vaccination should be taken in epidemic areas and farms, and the vaccine dose should be appropriately increased (it can be increased by 1 ~ 3 times) to reduce the incidence rate and control the spread of the epidemic.
(6) Strengthen the handling of dead pigs: isolate suspected sick pigs. Dead pigs and pollutants must be treated harmlessly, and it is strictly forbidden to sell and eat.
(7) Strengthen the disinfection of the environment inside and outside the site: once a month or half a month; Disinfect the pigs in the pigsty at least once a week 1 time; Disinfect the feeding utensils every 2-3 days; The disinfection pool at the entrance of the field and the entrance of each building should always change the liquid medicine to keep the disinfection liquid medicine effective.
(8) Strengthen management and improve the individual disease resistance of pigs. Provide the best living conditions, keep out the cold in winter and prevent heatstroke in summer, and the indoor air is fresh.
(9) Adhere to self-propagation and self-support. It is forbidden to buy commercial pigs. When it is introduced, it should be introduced from an epidemic-free area. After the introduction, it must be observed in isolation for more than 1 month, and the virulent antibody of classical swine fever is negative. Only after immunization with classical swine fever vaccine can they enter the market.
