Rooting is a fundamental behavioral need in pigs. Providing appropriate substrates for exploration and rooting significantly improves pig welfare and reduces problematic behaviors.
Behavioral deprivation is a serious welfare concern in intensive pig farming. The frustration of fundamental drives including exploration, rooting, and social investigation manifests as redirected behaviors including tail biting, ear biting, and aggression. Providing rooting substrates reduces these harms while simultaneously allowing pigs to express positive welfare states through natural foraging behavior. The mental and physical stimulation provided by appropriate substrates represents not just the absence of suffering but the presence of positive experiences.
