What are the precautions for the construction of pig farm isolation measures to better avoid diseases?
Biosecurity is the fundamental plan of a pig farm. No infectious disease will fall from the sky for no reason. The most common diseases affecting pig farms are PED, blue ear, pseudorabies, and swine fever.
