Environmental Enrichment

Zoos: Leading the way in implementing environmental enrichment

In this [oral] paper I shall review the contributions that zoo-based studies involving primates have made in improving the quality of life experienced by captive primates.

Environmental enrichment in a neurosurgical environment: the importance of licensee and technician communication

Unfortunately, few neuroscientists use environmental enrichment for their animals and some seem to be reluctant to change. This may stem from the view that enrichment can introduce an additional variable that will affect experimental results. A study is planned to...

Wire balls as enrichment for individually caged rabbits

The results presented here suggest that wire balls are a simple, cheap and effective enrichment technique for single-housed rabbits . However, over a three week test period the rabbit's interest in the ball declined slightly but not significantly.

Impact of home cage alterations on aggression in mice

PVC straight pipes, plumbing elbows and T pipes, and shreddible nesting squares were evaluated. Nesting squares appear to be the most effective enrichment object for reducing the incidence of aggression in group-housed male mice.

Environmental enrichment in laboratory rodents: Animal welfare and the methods of science

Examined types of and goals for the environmental enrichment of laboratory rodents. Studies concerning environmental complexity, social housing, and increases in cage size suggest that professional judgments are not a reliable basis for evaluating the outcomes of enrichment programs. Successful...

Environmental enrichment may alter the number of rats needed to achieve statistical significance

The aim of this study was to evaluate whether two enrichment items, an aspen tube and block, have any impact on commonly analysed clinical chemistry and physiological parameters of Wistar rats and - more importantly - on the extent of...

The use of aspen blocks and tubes to enrich the cage environment of laboratory rats

Female and male outbred Wistar rats (n=48) were allocated into three groups at weaning; control, tube and block groups (n = 8 males and 8 females in each) Animals were conventionally housed for five weeks in groups of four per...
