Environmental Enrichment

Behavioral effects of simple manipulable environmental enrichment on pair-housed juvenile macaques (Macaca nemestrina)

The teddy bear was preferred as a manipulable toy over the pink teething ring and the green teething ring. Toy use declined with time, indicating that rotation of toys, at least in the short term, may increase use.

Destructible toys as enrichment for captive chimpanzees

Nine singly caged chimpanzees were provided with eight different toys made of plastic, vinyl, or cloth one at a time or several at once. The toys remained in the cages an average of three days. The chimpanzees varied greatly in...

Environmental enrichment influences on pig behavior, performance and meat quality

Pigs were housed in pens containing eight animals each. The duration of basic behaviors .. were not significantly altered by the addition of environmental enrichment devices [two chains and two rubber hose devices hanging from above] or the incorporation of...

Choice tests with groups of mice: nest box, nesting material and tubes as enrichment items for laboratory mice

Mice show a preference for a more complex housing environment offering shelter. In accordance with results from preference tests with individually housed mice, present results support the view that nesting material, shelter, social contact and adequate space are important environmental...

Suggested Guidelines for Reptile Enrichment

Excellent recommendations for species-adequate, safe environmental enrichment options for various reptile species. Perching in most reptile enclosures is crucial in providing pathways and arboreal access for both semi and fully arboreal species. When supplied in conjunction with heat sources, perching...

Effects of cage type and gnawing blocks on weight gain, organ weights and open-field behaviour inWistar rats

Two separate experiments were conducted to study the environmental enrichment value of aspen gnawing blocks in solid bottom cages with bedding '(SBC) and in grid floor cages without bedding (GFC), and the effects of housing environments on the physiology and...
