A growing body of scientific research demonstrates the effectiveness of environmental enrichment in improving pig welfare, providing clear guidance for the industry.
The evidence base for pig enrichment is now substantial, showing clear welfare benefits from provision of appropriate manipulable materials. Straw and other organic materials satisfy pigs' rooting motivation most effectively. The challenge is implementing enrichment in systems with slatted flooring where substrate management is difficult. Innovation in enrichment design for slatted systems is an active research area.
