Environmental Enrichment

Woven vine balls and baskets as feeding enrichment for howler monkeys

Our results showed that the animals spent more time foraging when the feeder balls were used [compared to the baskets], since it was more difficult to reach the leaves. The monkeys also explored each of the baskets and stopped spending...

Animal welfare and enrichment: A preference study in the common marmoset (Callithrix jacchus)

In general, the results showed that the monkeys choose much less than expected between fruits cut and presented as usual in an open dish and fruit inserted as a whole in a pointed branch. When choosing a particual enrichment, it...

Environmental enrichment improves cognition in aged Alzheimer’s transgenic mice despite stable beta-amyloid deposition

Environmental enrichment (EE) has been shown to improve cognitive performance and brain indices of cognition in normal mice and rats. .. Beginning at 16 months of age, APPsw mice were put into EE or standard housing for 4 months and...

Environmental enrichment techniques in non-human primates

Suggestions for improving the welfare of common marmosets are presented both in terms of social life and physical environment. Background information is given on the ecology and behavior of common marmosets in the wild. It should be stressed that in...

Computer-assisted enrichment for zoo-housed orangutans (Pongo pygmaeus)

The study of environmental enrichment has identified a variety of effective forms of enrichment, but there are widespread problems associated with their use. Few forms of enrichment are cognitively challenging, and even the most effective often result in rapid habituation....

Housing and stereotyped behaviour: Some observations from an indoor colony of vervet monkeys (Chlorocebus aethiops)

Adult females displaying stereotypies in single cages were exposed sequentially to a foraging log and an exercise cage, as well as cages of varying complexity and dimensions. In another study females and males housed single in the bottom row, and...

Environmental enrichment facilitates amygdala kindling but reduces kindling-induced fear in male rats

Sixty male rats were housed either in an enriched environment or in isolation, starting immediately after weaning. As adults, they were subjected to either 50 amygdala-kindling stimulations or sham stimulations, followed by testing in an unfamiliar open field. The kindled-enriched...

Environmental enrichment for guinea pigs: A Discussion by the Laboratory Animal Refinement & Enrichment Forum

The question was raised how the environment of guinea pigs can be best enriched in the research laboratory setting. In summary, social-housing is the most species-appropriate living environment for guinea pigs. If a research protocol requires single-caging, guinea pigs should...
