Popis: There is increasing evidence that restriction of pre-parturient behaviour in pigs is stress-inducing, characterised by an elevation in hypothalamic-pituitary-adrenal (HPA) activity in gilts. To determine whether pigs adapt to behavioural restriction, through modification of nest-building behaviour, we studied pre-parturient pigs in either farrowing crates (no bedding, n = 7) or straw-bedded pens (n = 7) in their first (gilts) and second (sows) parity. with physiological measurements being taken in the second parity. Observations and blood sampling were carried out during the preparturient phase. Crated pigs changed posture more often than penned pigs (F-1,F-12 = 7.06, P
