Environmental Enrichment

An assessment of several potential enrichment devices for feedlot cattle

The enrichment devices consisted of a scratching/rubbing walkway, a moveable scratching/rubbing device, a milk-scent releasing device, a lavender-scent releasing device and a control non-scented device. The scratching/rubbing devices had higher durations and frequencies of use than the scent devices (P

Intervention with environmental enrichment after experimental brain trauma enhances cognitive recovery in male but not female rats

Motor function was assessed both pre-injury and for the first 5 days after injury. Spatial memory was assessed beginning 14 days after injury.Placement in an EE [environmental enrichment] after TBI [traumatic brain injury] enhanced spatial memory performance in male but...

The effects of environmental enrichment on murine immune response

Breeding pairs in cages that included enrichment (nestlets, jars, a ladder) had significantly fewer litter than the pairs in cages that did not (p

Influence of cage enrichment on aggressive behaviour and physiological parameters in male mice

From welfare perspective group housing of mice is preferred over individual housing. Group housing of male laboratory mice, however, often leads to problems due to excessive aggressive behaviour. ... Overall, nesting material reduced aggressive behaviour, while a shelter increased aggressive...

Effectiveness of enrichment devices during brief periods of social restriction in singly housed baboons

Data were collected on the animals' (three singly caged adult males) daily biscuit intake and activity levels as well as log activity prior to, during, and following social restriction (housed in separate room in which no other animals are present),...

Effects of environmental enrichment for mice: Variation in experimental results

Mice from enriched conditions [sawdust bedding, paper, nest box, climbing gird, gnawing blocks, tubes] weight more and consumed more food than mice from standard housing conditions. ... Mice from standard housing conditions were more active in an open field, suggesting...

Mirrors as enrichment for monkeys

We have a mirror for every single-cage, plus enough for at least one per pen in our group-housing facilities. Over 700 of our 950 monkeys now have access to a mirror (Bio-Serv, Monkey Shine Mirror). They have been hung for...
