An all-in, all-out system is implemented, the pig house is fully disinfected, and the pen must be empty for at least 7 days before a new pig group can be transferred. The stocking density is 1.2 m2 per pig, and 10 to 15 pigs per pen is appropriate. The temperature inside the house should be between 12 and 18°C, and epidemic prevention should be strengthened. Antibiotics can be appropriately added to the feed to help prevent the occurrence of gastrointestinal and respiratory diseases. At the same time, attention should be paid to driving out internal and external parasites, improving the feed conversion rate and slaughter rate, and shortening the fattening period.
