Abstract:

With the development of African swine fever control, it is more and more difficult for pig-raising farms to acquire land. In addition, the height of facility farmland cannot exceed two-storey is not conducive to the expansion of production capacity and transformation and upgrading of the pig-raising farms. The permission given by the state for the first time to pig-raising in large-scale buildings can save the area of pig-raising farms, and has high bio-security. This new model has gradually come into the public view. Based on the practical experience of engineering design and biological characteristics of swine, the key parameters of engineering design were discussed from 9 aspects, such as site selection, plane, architecture, pen, and etc. It could be seen from the technological process design that pig-raising in large-scale buildings is more fine and scientific, and the intensive degree is high. Pig-raising in large-scale buildings has the advantages of intensive land use, good biological safety, good environmental quality and high management efficiency, and the parameters proposed by this paper can provide theoretical reference for the construction of pig-raising farms adopting the new model and lay a foundation for the industrial development of pig-raising in large-scale buildings.

Key words: pig-raising in large-scale buildings, advantages, engineering design
