Rotational grazing systems for outdoor pigs provide welfare benefits through natural rooting opportunities while managing environmental impact and maintaining pasture quality.
Rotational pasture systems for outdoor pigs represent a genuinely high-welfare management approach that enables natural rooting in varied and enriched environments. The behavioral benefits of fresh pasture rooting exceed those of any indoor enrichment alternative. Environmental management through rotation maintains the system's welfare benefits sustainably. Welfare risks from weather exposure in outdoor systems require appropriate shelter provision. The higher land requirements and management complexity of outdoor rotational systems are offset by substantially better welfare outcomes for the pigs they house.
