Behaviours during the finishing phase (weeks 8–23) in percentage of behavioural scans for each treatment group: high and low IGEg pigs both in barren (B) and enriched (E) pens, with P values for the difference between IGEg groups (P-IGE), the difference between housing conditions (P-HC), and their interaction (IGE × HC)
