1. First investigate the purchase of pigs. The breeding pigs must be purchased from a large-scale breeding pig breeding farm with high reputation. The investigation and research work should be done first to understand the production and management status of the breeding pig farms, the epidemic prevention system, the nutritional status of the pigs, and whether it is a good breed, and then decide To purchase pigs, do not buy breeding pigs from pig traders. 2. Strictly quarantine the issue of strict quarantine for the purchase of breeding pigs.

The pig house should be thoroughly cleaned before entering the pig, washed repeatedly with high-pressure water, dried and then sterilized with 2% aqueous alkali solution, rinsed once with water on the 2nd day, dried and diluted with 1:2000 dilution of 100 poisonous spray 1 For the first time, empty the house for 3 days, and then use a 1:100 dilution of the bacterial enemy spray twice a day before entering the pig. 4. Drug Prevention After the introduction of breeding pigs, the drug prevention measures can be started from the second day. The following options can be used: (1) Add 10% florfenicol 120g per ton of diet, 130 grams of doxycycline, feeding for 7 days continuously (2) 400 grams of chlortetracycline powder or 400 grams of oxytetracycline powder is added to each ton of diet and continuously fed for 7 days; (3) 200 grams of amoxicillin powder is added per ton of water for 7 days. The above can prevent respiratory and gastrointestinal diseases, while reducing the pig's stress response. 5. Refill the vaccine in time. (1) On the 10th day after the introduction of breeding pigs, a swine fever vaccine, a live attenuated virus cell vaccine for swine fever and rabbits, 6 heads per intramuscular injection, a swine fever rabbit tissue vaccine or a bovine live vaccine, Two head cephalic injections. The swine fever vaccine was vaccinated once 30 days before the breeding, and then the swine fever vaccine was vaccinated 7 days to 10 days after each litter of the litter. The boar was vaccinated once a year in spring and autumn.

Later, the production sows and breeding boars will be vaccinated once every 3 months for four times. (3) One month after the breeding of the breeding pigs, the vaccine for pseudorabies gene deletion vaccine was inoculated with 2 ml per inosine and the sow was vaccinated again 2 months after the pregnancy. In the future, sows and boars are vaccinated once every 4 months for pseudorabies vaccine and 3 times for 1 year. (4) Breeding pigs should be given 1 dose of Japanese encephalitis vaccine at 150 days of age. One milliliter per musculature should be administered.
