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.

Enrichment in chimpanzees: Unpredictable ropes and tools

Chimpanzees preferred to play with ropes which acted unpredictably because the distant ends were in cages of other chimpanzees. Normal ropes were ignored.

Environmental enrichment: A review

The aims of this contribution are to look at three areas which are addressed by enrichment studies, within the context of a review: (1) the problems produced by spatial restriction, (2) the goals of enrichment, and (3) the evaluation of...

Long-term effects of a natural foraging task on aggression and stereotypies in socially housed pigtail macaques

A supplementary feeding of approximately one cup of sunflower seeds were dispersed throughout the cage in the woodchip bedding in the middle of the afternoons, 4-6 hours after the group was fed their daily ration of chow and fruit. ......

Filial imprinting, environmental enrichment, and music application – Effects on behavior and performance of meat strain chicks

In conclusion, these preliminary studies on the combined effects of filial imprinting, environmental enrichment, and music on the performance and behavior of meat type chicks, suggest the possible benefits of these procedures, such as reduction of stress behavior [fear response]...
