Play Behaviour as a Welfare Indicator in Pigs

Play behaviour in pigs is a positive welfare indicator, reflecting adequate nutrition, low stress and developmental wellbeing. Its presence or absence provides a rapid on-farm welfare assessment tool.

Key Facts

Piglets play spontaneously when healthy, well-fed and not overly stressed
Play frequency declines predictably when pigs experience pain, disease or social stress
Both locomotor play and social play are documented in pigs of all ages
Enrichment provision significantly increases play frequency in commercial settings

Welfare Considerations

The presence of play is a direct indicator of positive welfare states in pigs. Farms and research programmes that monitor play frequency can identify welfare deficits earlier than waiting for negative indicators like tail lesions or reduced weight gain. Encouraging play through enrichment provision represents a proactive welfare strategy.

What You Can Do

Provide enrichment materials that stimulate play including hanging ropes and rooting substrates
Use play observation as part of farm welfare self-assessment protocols
Support research into play as a welfare indicator in commercial pig production
Advocate for enrichment requirements to be strengthened in pig welfare legislation
