The temperature is low and the air is dry in winter. In order to ensure the healthy growth of pigs and reduce the occurrence of digestive tract diseases, respiratory diseases and infectious diseases in pigs, it is necessary to disinfect pigsty regularly or irregularly. Every building should have an empty fence to increase the number of patrols, so that pigs can be isolated and treated as soon as possible when they are sick.

Pay attention to details, increase patrol bars, check and seal doors, windows and gaps to prevent "cross flow" and "thief wind" from blowing in from rat holes and gaps in the circle. It is necessary to find and repair early, and not to create opportunities for diseases.
