Some peasants reared their pigs with pigs that lived with pigs. As a result, the pigs became sick again and even died, causing serious losses. For this reason, the pen must be sterilized before raising pigs. Disinfection methods are as follows:
After the pig house is sterilized, the house is cleaned and then 20% lime milk or 3% caustic soda water and 20% bleach are used for disinfection. The order of disinfection is walls, fences, doors and windows, food troughs, floors, appliances and doorway floors. Disinfectant can be brushed with a broom, preferably sprayed with a sprayer. After the disinfection is completed, the window and door of the pigsty should be closed for 2 hours to 3 hours before reopening, and the trough and ground should be rinsed with clean water.
Disinfecting the soil The soil surface shall be first cleaned of excrement, bedding, etc., and then the top layer of soil shall be removed. Finally, 20% of bleaching powder or 20% of lime milk and 3% of hot caustic soda shall be poured.
Manure and sewage disinfection A small amount of excrement, grass, etc. can be buried deep. If the amount of feces is more, fermentation can be used to disinfect. The method is to dig a shallow ditch a little further from the pig house, about 40 cm deep, about 2 meters wide, and the length depends on the amount of feces. At the bottom, first lay a layer of healthy swine manure, then pile the sick pig manure, cover a layer of healthy swine manure and weeds on the sick pig manure, and finally seal it with thin mud. When the pig manure is very thin, dry soil or dry comminuted grass can be added. When it is too dry, appropriate amount of water can be added to allow it to be fermented quickly. Summer and autumn about 1 month, winter and spring about 2 months, you can achieve the purpose of disinfection.
Sewage in diseased pig houses can be sterilized by fermentation in the faeces when there is a small amount. When the amount is large, 2% of quicklime powder or 0.2% of bleaching powder can be added to the total amount of sewage for disinfection.
