Answer: At present, there is no effective treatment for this disease, and it mainly relies on daily prevention. Specific measures include: ① Regular preventive injections. In addition to the general injection of attenuated swine fever rabbit vaccine for adult pigs in spring and autumn every year, weaned piglets and newly purchased pigs must be vaccinated in time. Dilute the attenuated swine fever rabbit vaccine with physiological saline according to the instructions on the bottle label, and inject 1 ml intramuscularly into both large and small pigs. Immunity will develop 4 days after injection. ② In areas where swine fever often occurs, piglets should be injected once 25 to 30 days old after birth, and again after weaning at 55 to 60 days old. The protection rate can reach 100%. ③Vaccination of pregnant sows can enhance the ability of mother and fetus to resist swine fever virus. Generally, a preventive injection is given one and a half months before sows give birth. ④Emergency immunization. In the pig herds where the epidemic has occurred, emergency vaccination can play a role in controlling the epidemic and preventing the spread of the epidemic. The injection can start with the pigs in the surrounding disease-free areas and disease-free pig houses, and then Pigs in the same group are injected, but sick pigs are generally not injected. In order to strengthen immunity, the dose can be appropriately increased during injection. ⑤ Strengthen feeding and management, conduct regular disinfection of pig pens, improve the overall disease resistance of pigs, and avoid purchasing pigs from epidemic areas. Newly purchased pigs should be quarantined and observed for 30 days, confirmed to be disease-free, and injected with swine fever vaccine before being mixed into the herd. ⑥During the epidemic period of swine fever, feeding equipment should be disinfected every 3 to 5 days. After the sick pigs are disinfected, the feces and dirt should be completely eliminated, the topsoil should be eradicated, and new soil should be added. The pig manure should be accumulated and fermented.
