Pig Welfare and Cognitive Enrichment Science

Cognitive enrichment for pigs exploits their significant intelligence to improve welfare through problem-solving and learning opportunities.

Key Facts

Pigs have demonstrated cognitive abilities comparable to dogs and young children in some studies
Enrichment that requires problem-solving to access food rewards engages pig intelligence meaningfully
Novelty is essential - pigs quickly learn to solve familiar problems and need new challenges
Cognitive enrichment reduces boredom-related behaviors including tail biting and aggression
Positive cognitive experiences are associated with positive affect states in pigs

Welfare Considerations

Pig intelligence is an underappreciated welfare resource - the same cognitive abilities that make pigs good problem-solvers also mean they experience boredom acutely when environments offer insufficient challenge. Cognitive enrichment is both welfare-improving and practically achievable.
