Physical environment design in pig housing — including flooring, temperature management, lighting, and space allocation — directly determines daily welfare for millions of individual animals.
The physical environment of pig housing determines the quality of every hour of a pig's life. Floor type, temperature, lighting, and space allocation are not engineering details — they are welfare determinants that affect comfort, health, and natural behaviour expression continuously. Investment in environmental design that provides bedded lying areas, appropriate temperature management, and adequate space produces measurable welfare improvements and often accompanies productivity benefits from reduced disease and better growth.
