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...

Guinea pigs

Initial attempts to provide the animals a covered area for refuge showed that the guinea pigs adopted the shelter very quickly and would dart under cover when startled. ... We soon realized that this was a most useful behaviour when...

Studies of disturbed behaviour in macaques

Stereotyped locomotion amounted to about 20% of the time when the subjects were housed solitary. The amount of time spent in this behaviour was reduced to about 4% when the subjects had one or more social partners. Stereotyped locomotion was...

The use of naturally occurring manipulanda can reduce the frequency of cage stereotypy in solitary-housed primates

The single-housed animals demonstrated a marked reduction of cage stereotypy during the time they had the corn to manipulate.
