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...

Effects of different environmental enrichment devices on cage stereotypies and autoaggression in captive cynomolgus monkeys

Autoaggression and stereotypies in individually housed cynomolgus monkeys were compared in a standard primate cage and an enriched playpen environment. Stereotypy and autoaggression were markedly reduced in the playpen, but reappeared on return to the home cage. Some of the...

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...

Examination of various foraging components and their suitability as enrichment tools for captively housed primates

Vertically mounted foraging racks are beneficial because they increased locomotion, decreased hoarding, and appeared to increase the [group-housed] animals' interest in the feeding task.
