Pig Dust Bathing and Rooting Welfare

Dust bathing and rooting are highly motivated natural behaviours in pigs that are largely frustrated in intensive production systems, representing a significant welfare problem.

Key Facts

Pigs are highly motivated to root, spending hours daily engaging in this behaviour in natural environments.
Rooting and foraging behaviours are driven by strong internal motivation that does not diminish even when pigs are well-fed.
Frustration of rooting motivation in barren environments contributes to redirected abnormal behaviours including tail biting.
Wild boar and extensively kept pigs engage in wallowing and dust bathing for thermoregulation and skin health.
Providing rooting substrate such as straw, compost, or peat reduces aggression, abnormal behaviour, and cortisol levels.

Welfare Considerations

The near-total frustration of rooting motivation in slatted intensive pig housing is one of the most serious chronic welfare issues in modern animal agriculture. Pigs in these systems cannot express fundamental drives and show persistent evidence of frustration and stress. Providing even minimal rooting substrate has measurable positive effects on welfare and is increasingly required under enhanced welfare standards.

What You Can Do

Choose pork certified under higher welfare standards such as RSPCA Assured or certified outdoor bred.
Support policy campaigns for mandatory environmental enrichment substrate requirements in pig farming.
Reduce pork consumption and replace with plant-based proteins where possible to reduce demand for intensive systems.
