Farmed Pig Housing Litter Enrichment

Providing substrates for rooting and nesting in pig housing addresses fundamental behavioral needs and reduces welfare-compromising behaviors.

Key Facts

Pigs without rooting substrate redirect rooting to pen mates, causing injury
Straw provision dramatically reduces tail biting and aggression in indoor pigs
Slat floors prevent providing deep straw in many existing barn designs
Partial bedding solutions like hanging straw racks offer compromise approaches

Welfare Considerations

Rooting is not a luxury behavior but a fundamental drive in pigs that was shaped by millions of years of evolution. Frustration of this drive in barren concrete environments causes chronic thwarting that is measurable in stress hormones and behavior. Substrate provision is among the simplest and most effective welfare interventions.

What You Can Do

Support certification programs that require substrate provision for pigs
Advocate for substrate mandates in pig welfare legislation
Choose pork from farms that provide rooting material for their pigs
