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,

Oxytocin plays an important role at parturition due to its involvement in uterine contractions, foetal expulsion and the onset of maternal behaviour. The role of the related neurohypophysial hormone, vasopressin, is less clear; however, there is some

Contents Previous studies have shown an increase in plasma cortisol in gilts over farrowing irrespective of environment suggesting that factor(s) associated with parturition itself cause physiological stress. Factors involved in mediating the hypatha

The aim of this study was to describe maternal behaviour in the pig and to investigate the effect of endogenous opioids on maternal responsiveness. The behaviour of 16 Large White×Landrace female pigs was recorded around farrowing which involved rec

In a previous experiment the provision of straw to group-housed pigs increased the number of daily feeder visits. This effect of straw is comparable with conditions of reduced social competition for access to the feeder. The aim of this experiment wa

Single-space feeders used in pig selection may favour those pigs which control access to the feeder. This was not the case when straw bedding was provided (Nielsen et al. 1995). However, straw may have modified behaviour and masked the effects of agg

This study examined the temporal relationships between behavioural activity and hormones associated with stress in gilts farrowing in two environments. Thirty-one Large White × Landrace gilts with indwelling jugular catheters were blood sampled dail

It has been suggested that feeding motivation and feeding behaviour are causally related to the performance of persistent oral behaviour in pigs. However, in a previous experiment we showed that the presentation of small food rewards to chronically f

Nest-building in the pig is thought to be stimulated by a pre-parturient surge in prolactin. There is concern that sows in crates may experience psychological stress as a result of physical interference with nest-building. Thirty-three gilts were imp

Maternal oestrogen and progesterone have been shown to be important in the initiation of maternal behaviour. Thirty-three Large White x Landrace gilts, housed in groups during pregnancy, were observed and aggressive interactions recorded. Individuals
