Rotational enrichment programs for pigs systematically vary enrichment materials to maintain novelty, sustained engagement, and welfare benefits throughout the production cycle.
Static enrichment in pig systems often becomes ineffective within days as pigs lose interest, restoring the boredom and frustration that enrichment is meant to address. Rotational programs address this by systematically introducing novel materials that maintain behavioral engagement throughout the production cycle. This sustained enrichment has been shown to maintain lower cortisol levels, reduce tail biting incidents, and preserve more complex behavioral repertoires. The welfare benefits of well-designed rotational programs are substantially greater than the minimal compliance enrichment common in many commercial systems.
