There are a large number of fine particles in the air of the piggery, which are mainly composed of five aspects: the feed ash, the air and the natural dust in the air of the piggery, the aerosol particles produced by the pig's respiration, the skin shedding of the pig body, and the volatiles after the drying of the pig's feces. The latter three are particularly important. A pig's sneezing can produce millions of aerosol particles. Coughing and Howling can produce aerosols, such as saliva, mucus, etc., called droplets. The residual water in the droplet is mucus protein, microorganism and so on. It is called the droplet nucleus. More than 90% of the droplet diameter is less than 5 m, and the diameter of the droplet core is generally 1~20 m.
We know that PM10 refers to the solid and liquid particles of the aerodynamics below 10 microns, which can not be landed on the ground by its own gravity, so it is also called floating, some days, even a few years.
These fine particles in the piggery are light weight and float in the air for a long time. When the environment is suitable, they drift along with the wind and spread diseases. It is reported that foot-and-mouth disease virus can be transmitted by air for 20 kilometers. I think in order to prevent blue ear disease, it is also the reason why the pig house is equipped with piggery filtration equipment.
When these fine particles are spread through the wind, the first station is the surface of the pig house, such as the surface of the pig house, such as the roof of the pig house, and so on. If it can be sterilized in time, it can reduce the occurrence of the disease, so it is very important to disinfect it.
The improved method is to disinfect the vacant land, grassland and pig house roof outside the pig house. It is recommended to install regular spray disinfection equipment and regularly disinfect inside and outside the pig house.
