Pig pen design affects welfare through social density, substrate quality, feeding access, and enrichment provision. Evidence-based design significantly improves welfare outcomes.
Pig pen design is a welfare foundation that affects behavior, health, and social dynamics across the entire time pigs occupy the space. Getting design right at construction is far more cost-effective than retrofit. Evidence-based pen design incorporating shape, substrate, feeding station number, and enrichment placement provides a significant welfare return on architectural investment.
