Environmental Enrichment

Modifications to husbandry and housing conditions of laboratory rodents for improved well-being

A review of the literature shows that a consensus on the definition of changes constituting environmental enrichment has yet to be reached. For this reason, the results of studies on the effects of rodent enrichment are inconsistent. In many cases,...

Effects of a cage enrichment program on heart rate, blood pressure, and activity of male sprague-dawley and spontaneously hypertensive rats monitored by radiotelemetry

Enrichment comprised a simulated burrow (Rodent Retreat), then a food foraging item (rat cannoli) 2 days later, and a paper bag of bedding for shredding (Nestpak) after another 2 days. Data were collected under undisturbed conditions and before and after...

Foraging device for cynomolgus macaques

A foraging device is described. We do not use it to feed our primates their daily rations, just to provide an enrichment opportunity for them. No data are included in this article.

Environmental enrichment to address behavioral differences between wild and captive black-and-white ruffed lemurs (Varecia variegata)

Behavioral enrichment experiments were carried out in which whole rather than chopped fruit was provided and presented in a more naturalistic manner [whole fruit suspended by sisal or jute from wooden polses]. ... Manual manipulation of dietary items increased. Time...
