Farmed Pig Rooting Behaviour and Welfare

Rooting is one of the most fundamental behavioural needs of pigs, and its restriction in intensive systems causes significant welfare deprivation.

Key Facts

Pigs use their snouts to root through soil to find food in natural settings
The rooting motivation persists regardless of whether pigs are fed adequate diets
Straw and compost rooting substrates allow expression of rooting behaviour
Concrete slatted floors prevent rooting and cause boredom and frustration
Pigs with rooting substrate show lower stress hormones and fewer stereotypies

Welfare Considerations

Pigs denied rooting material cannot express one of their most fundamental behavioural drives. This deprivation causes chronic frustration that manifests as aggression, stereotypy, and redirected rooting behaviours. Providing any manipulable substrate improves welfare, with straw being the gold standard for rooting enrichment.

What You Can Do

Support welfare certification requiring rooting substrate for all pigs
Advocate for straw provision as a minimum welfare standard
Choose pork from farms that provide pigs with rooting materials
