Pigs are highly intelligent animals with strong drives to root, explore, and manipulate objects. Providing enrichment in farm environments reduces stress, stereotypic behavior, and aggression.
Enrichment provision for pigs addresses one of the most significant welfare deficiencies in intensive production systems. Pigs have complex behavioral needs that cannot be met in barren concrete environments, leading to frustration, aggression, and self-harm through tail biting. Tail biting is so common in commercial pig farming that routine tail docking — itself a painful procedure — is practiced as a preventive measure rather than addressing the root cause. Providing enrichment that engages rooting and exploratory behavior reduces tail biting without docking, representing a win for both welfare and responsible husbandry. Consumer demand for higher welfare products and regulatory compliance incentivizes this relatively low-cost improvement.
