How to prevent swine erysipelas? Prevention and control methods every pig farmer must read

(1) Eliminate the source of infection: regularly disinfect pig pens by spraying with 10% carbolic acid emulsion, at least 2 to 3 times a year.

(2) Eliminate transmission factors: the cause of disease in many pig farms is buying in pork from outside, so breeding and raising your own pigs is the key to preventing swine erysipelas.

(3) Improve the pigs' disease resistance: give pigs reasonable feeding and management, feed more green fodder, allow proper exercise, clean out the bedding and pens every day, check the pigs' health status every day, and isolate and treat sick pigs promptly when found.

(4) Get vaccinated against swine erysipelas with attenuated vaccines on schedule: domestically, the main vaccines used are freeze-dried attenuated live vaccines of the GC42 and G4T(10) strains; weaned pigs can be immunized for 6 months after vaccination. The GC42 attenuated freeze-dried vaccine can be given orally as well as by subcutaneous injection, making immunization more convenient. The triple vaccine already produced in China (swine fever, swine erysipelas, swine pasteurellosis) is relatively popular; it not only saves labor but also saves time, and with the combined vaccine, the immunity period for swine fever is more than 8 months, while for swine erysipelas and swine pasteurellosis it is 6 months.

(5) Prevention and control measures after an outbreak are as follows: ① Immediately seal off the infected site when sick pigs are found, carry out thorough disinfection, pile up manure for fermentation, and isolate and treat sick pigs promptly. ② Carcasses of sick pigs must be burned and then buried deep, and contaminated sites and equipment must be thoroughly disinfected to strictly prevent the spread of the disease. ③ In any area where the disease has occurred, the lockdown can be lifted on the 8th day after the last sick pig falls ill. At the same time, vigorously carry out one strict disinfection to eliminate the source of infection as much as possible. ④ After carrying out a comprehensive large-scale disinfection, preventive injection is still required; before the vaccine produces immunity, pay attention to prevention and treatment and monitor the epidemic situation to prevent recurrence.
