Straw as Pig Enrichment: A Low-Cost Welfare Solution

Providing straw to pigs is one of the most evidence-supported and cost-effective welfare improvements, dramatically reducing tail biting and improving pig wellbeing.

Key Facts

Pigs provided with straw spend up to 50% of time rooting and exploring it
Tail biting incidents fall by 80%+ in enriched systems with adequate straw
EU law requires manipulable material for pigs but compliance is inconsistent
Straw provision costs pennies per pig per day — one of the cheapest welfare improvements
Deep straw yards provide full expression of rooting, nesting, and foraging

Welfare Considerations

Pigs have an intense innate motivation to root, forage, and explore. In barren concrete pens, this motivation is redirected to tail biting — a serious welfare problem causing pain and infection. Straw provision satisfies rooting needs, reduces aggression, and provides occupation for the 60-70% of time pigs spend being active. The welfare benefit per unit cost is among the highest of any farm intervention. Resistance from producers focuses on slurry management costs rather than animal benefit.
