Environmental enrichment for pigs: Differences in somatosensory cortical neurons and subsequent behaviour

Pigs raised in a windowless building with hanging rubber hose toys and weekly petting were less excitable compared to pigs raised with no extra environmental stimulation. Pigs exposed to an enriched environment approached novel objects more quickly than animals raised...

Neighbour effects and the stress of tethering in sows

Repetitive behaviour of newly tethered gilts correlated positively with that of their neighbours. .. The data suggested that behaviour of neighbours was not just being copied, but itself produced stress, and it seems likely that the noise of chain chewing...

The influence of pleasant and unpleasant handling and the provision of toys on the growth of male pigs

Provision of toys [chains, tyres, bars] .. is suggested to have improved the welfare of the [group-housed] pigs by reducing their fear of humans, irrespective of the type of handling.

Behavioral principles of livestock handling

Reducing stress during handling will improve productivity and prevent physiological changes that could confound research results or lower productivity. Handling stresses lower conception rates and reduces both immune and rumen function. Handlers who understand livestock behavior can reduce stress. Livestock...

The influence of different social and physical environments on the incidence of lactational oestrus in sows

The family pens contain an activity area with straw and a rooting area with peat and bark. This environmental enrichment increases the foraging activity of the sows and probably further reduces the amount of time they spend in close contact...
