(1) Strengthen feeding and management The pig production should be done in all-in and all-out way: Since the breeding and self-cultivation, the breeding pigs and the finishing pigs should be kept separately and relatively isolated. In the hot season, do a good job in ventilating the pigs' house and prevent it from cooling. Provide enough clean drinking water to keep the pig house dry. Maintain a reasonable stocking density, reduce the number of swarm herds and groups, and reduce stress factors. Do not use mildew and poor quality feed to ensure adequate nutrition and enhance the disease resistance of herds. We will actively promote the standardization and standardization of rearing methods and raise the level of pig production. (2) Strengthen the environmental disinfection and timely remove pig manure and excrement to keep the environment clean. Each week, the pig farm environment and the pens were thoroughly disinfected 2 to 3 times to reduce and eliminate the pathogenic microorganisms contaminated in the pig farm and reduce or eliminate the exogenous secondary infection in the pigs. In the hot season, the number of disinfections should be increased; the diseased pighouse should be disinfected 1 or 2 times a day. (3) To carry out immunization prevention According to the local epidemic situation, the majority of farmers should actively contact the local animal epidemic prevention station to strengthen the foot-and-mouth disease, swine fever, pig reproductive and respiratory syndrome (Larr disease), pseudorabies virus, and swine lung disease. The vaccination of swine erysipelas, E. coli disease, piglet paratyphoid and other diseases uses scientific immunization procedures to effectively control the occurrence of these diseases.
