1. Regular sterilization: When using the factory-based segmented pig raising process and the all-in all-out production method, for each individual pig raising unit, due to its better closure and higher requirements for environmental control, its sterilization The more stringent. The usual practice is to thoroughly clean and wash the pens after the unit is vacated. The pig bed, under-bed sewage ditch, floor and walls, incubators, insulation boards, ceilings, feeding troughs, etc. should be carefully cleaned of manure. Do not leave dead corners, wash after spraying potassium hydrogen persulfate composite salt powder for several hours. When it is not yet dry, close doors and windows for fumigation, ventilate after 24 hours, and dry for at least 7 days before entering pigs. Conditional farms should check the sterilization efficiency before entering the pigs, and should be sterilized again if they are unqualified.

2. Local sterilization: using traditional pig raising technology, non-full-in and all-out production methods, this method can be used to sterilize the pens that are vacated after weaning, transfer to groups or after pigs are sold. The method is to clean the pen, wash it with high-pressure water, pour potassium hydrogen persulfate on the ground, wall, trough, and sink. After a few hours of sterilization, wash the sterilization liquid with clean water, and then enter the pig after drying.

3. Antibacterial prevention: It is a routine epidemic prevention measure to keep the pig house clean and hygienic, reduce the density of pathogens in the house, and prevent the occurrence and prevalence of disease in pigs. The method is to clean the ground and road of the pig house twice a day, once in the morning and once in the afternoon, and transport the collected feces, feed residues, bedding, etc. to the manure yard for centralized treatment. At the same time, the troughs, troughs, and drains are cleaned daily or Use potassium hydrogen persulfate compound salt powder to spray the ground, walls, and walkways to eliminate bacteria every week. When the epidemic situation is serious off-site, it should be disinfected once a day.

4. Terminal sterilization (big sterilization): After a large-scale outbreak and epidemic of the disease, a pig of the disease died, culled, and moved out. After a long incubation period of the disease, no new disease occurs. Potassium hydrogen persulfate was used throughout the entire field for overall sterilization. The principle to be mastered is to eliminate bacteria first in the area without disease, then eliminate the disease area; first eliminate the bacteria outside the pig house, and then eliminate the bacteria inside the pig house. The environment outside the pig house should be cleaned up and the site should be cleaned. The feces and garbage should be incinerated. The cement surface should be sprayed with antimicrobial agent. Potassium hydrogen sulfate should also be used on the soil that the diseased pigs have contacted. Perform sterilization. The sterilization in the house can be carried out according to the aforementioned procedure, and the concentration of the sterilization agent can be appropriately increased when necessary.

5. Sterilization of drinking water: When rivers, lakes and ponds are used as drinking water sources without filtration, the potassium hydrogen persulfate composite salt powder can be added to the water through a dosing device or a water tower to sterilize it.
