Description
Valfré and colleagues tested how nursery enrichment shapes resilience in more than six hundred piglets on a commercial farm. Litters received a single chain, chains plus a weekly rotated extra object, or several objects at once. A subsample later faced an attentional bias test, while the team also scored behavior qualitatively and measured hair cortisol and a brain growth factor in blood.
Attention measures barely separated the groups, but coping behavior did: each treatment showed a distinct pattern of excretion, standing, or escape attempts. Piglets with several objects looked calmer and less tense, while the single-chain group carried higher cortisol and lower growth factor. Enrichment style, the authors argue, tunes stress biology.
