Environmental enrichment for confinement pigs

Pigs have definite toy preferences. If a ball rolls into the manure they will no longer play with it. This is why we used suspended from the ceiling. Then the young pigs are given a choice between hanging chains, cloth...

Measuring hunger in the pig using operant conditioning: The effect of food restriction

Using operant methods, it was demonstrated that boars fed at maintenance levels may be constantly hungry. The hunger resulting from low food levels may act as a major source of stress under certain husbandry conditions such as tether and stall...

Enrichment of the production environment and the enhancement of welfare through the use of the Edinburgh Family Pen System of pig production

Pigs in family pens [four sows with offspring in four pens each furnished with nest area, activity area, peat area, connecting faeces corridors, a familiar mature boar joining the group for a period from day 14 to day 56] exhibited...

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...
