1. Save land:
Pig houses can be superimposed for raising pigs in buildings, which greatly saves the required land area compared with raising pigs on flat floors.


2. Conducive to biological security prevention and control:
When all the pig houses are centralized, the entrance to the pig house is reduced, which is especially beneficial to the control of personnel entering the pig house, the disinfection of materials entering the pig house, and the prevention of mosquitoes, insects and wild animals  from entering.


3. Convenient management:
When the pig houses are centralized, personnel management and pig herd management are more convenient.
