Pig Pen Enrichment Complexity and Welfare Outcomes

More complex enrichment providing multiple sensory stimuli and challenges produces better welfare outcomes than single objects.

Key Facts

Complex enrichment combining rooting substrate, hanging objects, and foraging challenges is more effective than single items
Novelty is essential - familiar objects lose their value rapidly
Enrichment placed at the back of pens encourages exploration of full pen space
Edible enrichment combining nutritional and behavioural value is particularly effective
Pigs show individual preferences requiring variety to satisfy all pen members

Welfare Considerations

Enrichment research has advanced from simply asking whether any enrichment helps to understanding what characteristics make enrichment most effective. Complexity, novelty, and engagement are key. Providing a variety of enrichment types that meet different behavioural needs - rooting, chewing, social interaction, and exploration - delivers the best welfare outcomes for pigs across their range of individual preferences.

What You Can Do

Support enrichment complexity requirements in pig welfare standards
Advocate for enrichment budgets in farm welfare codes
Share enrichment research with pig producers to improve practice
