Despite EU legal requirements for enrichment materials for pigs, compliance auditing reveals persistent failures that leave millions of pigs without the enrichment the law requires.
Pig enrichment compliance is a case study in the gap between law and practice in farm animal welfare. The EU directive requiring enrichment has been on the books for over 20 years, yet audits consistently find that half or more of farms in many countries are non-compliant. This is not an area of scientific uncertainty -- the welfare science is unambiguous that pigs need manipulable materials. It is a failure of enforcement. Penalties for non-compliance are rarely proportionate to the welfare harm; inspectors are too few; audit frequency is too low. Systemic enforcement reform rather than further legislation is the primary need for pig enrichment welfare.
