Pig Enrichment Complexity and Cognitive Stimulation

Pigs are cognitively sophisticated animals that require complex, changing enrichment to prevent boredom, frustration, and abnormal behaviours.

Key Facts

Pigs can learn to operate touchscreens and video game controllers in research
They show optimistic cognitive bias when provided positive environments
Simple static enrichment like hanging chains loses appeal within days
Rotating novel enrichment objects maintains interest and reduces aggression
Foraging enrichment activates the reward pathway and promotes positive emotional states

Welfare Considerations

Boredom is a genuine welfare concern in pigs housed without adequate cognitive stimulation. Enrichment programmes that challenge pigs with novel, changing, manipulable materials meet their cognitive needs and reduce abnormal behaviours substantially.

What You Can Do

Support welfare standards requiring complex and rotating enrichment for pigs
Advocate for research into cost-effective enrichment delivery at commercial scale
Choose pork products from enriched housing systems
Learn about pig cognition to better understand their welfare requirements
