Pigs are among the most intelligent farm animals, with cognitive abilities comparable to dogs. Meeting their behavioral needs — particularly rooting — is central to pig welfare.
Pig behavioral deprivation is one of the most ethically significant welfare problems in animal agriculture. Pigs are highly motivated to root — they will root even on concrete for hours — and denying this behavior causes frustration that manifests as redirected aggression, stereotypies, and tail biting. Tail docking, which removes the target of biting, is a surgical solution to a management problem: instead of providing enrichment, the industry removes the body part that is being bitten. The EU prohibition on routine tail docking is widely ignored because enrichment requirements are simultaneously unenforced. Farms that genuinely provide straw bedding and rooting materials show dramatically lower tail biting rates and do not require docking.
