Includes structural, behavioral, food, and auditory enrichment.
As part of a multi-institutional study of zoo elephant welfare, we evaluated female elephants managed by zoos accredited by the Association of Zoos and Aquariums and applied epidemiological methods to determine what factors in the...
Environmental enrichment (EE) reduces drug and sucrose cue-reactivity in rats. In a previous study we reported that 1 month of EE (large cage, toys, and social cohorts) significantly reduced sucrose cue-reactivity. In the present study...
Many pet cats are kept indoors for a variety of reasons (eg, safety, health, avoidance of wildlife predation) in conditions that are perhaps the least natural to them. Indoor housing has been associated with health...
A heavy metal cylinder, 60 cm long and 45 cm in diameter, was capped on each end and bolted to a platform. Three 8 cm holes in the cylinder allowed access to the inside. A...
After converting our dog holding facilities from commercial dog cages to pen type enclosures, it became apparent that suitable resting platforms were needed. Clear acrylic plastic was used to construct the resting platforms.
Mice were reared in either enriched (EE), social control, (SE), or impoverished (IE) environments for 30 days. Environmental enrichment results in a significant and selective increase in paradoxical sleep (PS, or REM sleep) and also...
The enriched boxes were similar to the bare ones but also contained the following objects: two large red rubbing bungs, a golf ball, a bottle top, two coloured table tennis balls hanging from the cage...
Supplying straw reduced tail biting in group-housed pigs.
Weaned piglets housed with straw performed less tail-biting, rooting, massaging, and nibbling of pen-mates than pigs reared without straw.
Sixty-seven animals from eight primate species were used to assess improved husbandry techniques. The presence of woodchips as a direct-contact litter decreased inactivity and fighting, and increased time spent on the ground. Placing food in...
