Environmental enrichment of brown capuchins (Cebus apella): Behavioral and plasma and fecal cortisol measures of effectiveness

Plasma cortisol was significantly predicted by the proportions of both normal and abnormal behaviors; as the proportion of normal behavior increased, the plasma cortisol measures decreased. ... In light of our experimental findings that a variety of EE [environmental enrichment]...

Enrichment in group-housed laboratory golden hamsters

Enriched hamsters [four same-sexed animals per group] showed varied behavior and less aggression toward their cagemates. The hamsters preferred jars to pipes probably because the jars' greater height, as compared to pipes, made it easy to look outside the cage.

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.
