Rotating enrichment items prevents habituation and maintains exploratory behavior in pigs — an evidence-based approach that improves welfare without significantly increasing production costs.
Pig enrichment science has advanced from simple provision of static objects to dynamic, rotated programs designed to maintain behavioral engagement. The evidence base for rotation is clear: novelty drives exploratory behavior, which meets intrinsic motivational needs and reduces redirected aggression. Implementation requires a systematic rotation schedule, variety in material types, and sufficient quantity to prevent competition. The welfare return on enrichment investment is substantial — reductions in tail biting, veterinary costs, and antibiotic use make enrichment programs economically compelling.
