Pigs in intensive systems are highly intelligent animals whose welfare depends critically on opportunities to root, explore, and manipulate objects — yet many farms provide little or no enrichment.
Pigs are among the most cognitively sophisticated farm animals, with intelligence comparable to dogs. Without enrichment opportunities, they experience chronic boredom and frustration that manifests as aggression, tail biting, and stereotypic behaviors. The combination of high intelligence and barren environments creates intense welfare compromise for hundreds of millions of pigs globally.
