Rooting is one of the most fundamental and strongly motivated behaviors in pigs. Providing appropriate rooting substrates in commercial settings dramatically improves welfare and reduces problematic behaviors.
Denying pigs the ability to root is a fundamental welfare violation. The frustration of this highly motivated behavior causes chronic psychological stress manifested in stereotypies, aggression, and redirected behaviors like tail biting. Tail biting causes serious physical suffering and can escalate to severe injuries and death. The industry-wide response of routine tail docking to manage tail biting addresses the symptom while ignoring the cause. A welfare-centered approach provides appropriate enrichment that meets rooting motivation, making tail biting less likely while respecting the behavioral needs that define pig nature.
