In other words, this warm and wet condition is also suitable for every colonization and growth of microorganisms. Dust is also a carrier of microorganisms. In the poorly ventilated or often sunlit enclosures, dust promotes the proliferation of various types of microorganisms, with up to 1 million bacteria per cubic meter of air. Among the common microbial species in piggery, the amount of Aspergillus flavus and Mucor sp. And more saprophytic bacteria, actinomycetes and so on. A lot of germs of pigs can be transmitted through dust. Dust itself has a direct effect on the health of the pig. Dust lands on the surface of the pig's body and forms scalp, which affects the heat of the skin, causing itching, even inflammation, dryness, and rupture. A large amount of dust falls on the conjunctiva and can cause conjunctivitis. Dust is inhaled into the respiratory tract by the pig and can cause conjunctivitis on nasal mucosa.
