Environmental Enrichment

A gravity roulette feeder for chimpanzees

A few chimps will use sticks or branches to knock the enrichment items down the hole in the platform and then climb down and get the treats at the openings. Sometimes it works - sometimes it doesn't, because other chimps...

Effects of enrichment and floor type on behaviour of cubicle loose-housed dry sows

Spent mushroom compost is presented to the pigs as a rooting medium suspended over their housing on flat wood and wire racks as this removes the need for extra space allowance. The use of this substrate reduces aggression and injuries...

Observations on the prevalence of nest-building in non-breeding TO strain mice and their use of two nesting materials

Within 2-3 min of the nesting materials being placed in the cages, many mice had pulled the paper towel from the pot into the main cage, investigated, chewed and manipulated the sheet. ... Thirty-six of the mice constructed nests during...

Environmental enrichment for dairy calves and pigs

Frequency of cross sucking was greater for calves in pens without enrichment devices [gadgets triggering sucking and chewing]. .. Both the ball and chain were used very little.

Comfortable quarters for laboratory dogs

Comprehensive enrichment program is outlined. It is reasonable to recommend that as an absolute minimum the enclosure must provide adequate space for a dog to locomote for more than a few paces in a straight line. This can be provided...

Evaluation of objects for environmental enrichment of mice

Single-cage mice spent 3.58 min interacting with the marble, 50,16 min interacting with the tunnel, and 271.00 min interacting with the nestlet. Control animals spent a mean of 35 min digging in bedding, suggesting that bedding served as an important...

Effects of cage enrichment on territorial aggression and stress physiology in male laboratory mice

Findings suggest that keeping adult male mice in structured cages can result in increased aggression towards intruders, a change in the social organization, and altered endocrine states.
