Pig Welfare and Straw Provision

Straw provision is one of the most evidence-based enrichment interventions for pigs, satisfying multiple natural behavioural needs simultaneously. Its widespread adoption remains a welfare priority.

Key Facts

Straw satisfies pigs' rooting, chewing, and nesting behavioural needs simultaneously
Even small amounts of straw significantly reduce stereotypic rooting behaviours
Straw provision reduces tail biting by reducing behavioural frustration in groups
Sows with straw for nest building show less stereotypy and better maternal behaviour
Practical straw management in slatted floor systems is challenging but achievable

Welfare Considerations

Straw provision is the single most evidenced enrichment intervention for pig welfare, with benefits documented across multiple welfare domains including physical health, natural behaviour expression, and reduced aggression. Its practical challenges in slatted floor systems have slowed adoption but are not insurmountable. Prioritising straw provision as a welfare requirement should be a core objective of pig welfare standards.
