Different types of environmental enrichment vary significantly in their ability to meet pigs natural behavioral needs, with species-appropriate substrates most effective.
Not all enrichment is equally effective at improving pig welfare. Pigs prefer and benefit most from substrates including straw and compost that allow rooting and foraging. Hanging objects and toys provide some relief from boredom but do not satisfy the same motivational drives. Understanding pig enrichment preferences allows better welfare investments that genuinely improve behavioral opportunities.
