Environmental Enrichment

Positive reinforcement training as enrichment for singly housed rhesus macaques (Macaca mulatta)

Positive reinforcement training is one component of behavioural management employed to improve psychological well-being. There has been regulatory promotion to compensate for restricted social housing in part by providing human interaction to singly caged primates, implying an efficacy standard for...

Enrichment and behavioral management programs around the world

To do justice to the diverse approaches to enrichment and behavioral management around the world would entail a discussion beyond the limits of this publication. Therefore, guidelines and regulations in a representative sample of countries in select regions of the...

Frustration and perseveration in stereotypic captive animals: Is a taste of enrichment worse than none at all?

Stereotypic behaviours are common in animals in impoverished housing, arising from two complementary processes: (1) thwarted attempts to perform motivated behaviours; (2) forebrain dysfunction impeding normal behavioural inhibition. When enriched animals are moved to impoverished housing, they are sometimes protected...

Forebrain cell proliferation, behavior, and physiology of zebrafish, Danio rerio, kept in enriched or barren environments

Comparative studies on neural plasticity in non-mammalian vertebrates are increasingly promoted as an important complement to mammalian models. In teleost fishes the number of brain cells increases with age, body weight, and body length throughout life. Neurogenesis persists to a...

The effect of mirrors on the behaviour of singly housed male and female laboratory rabbits

It is widely recognised that single housing is detrimental to the welfare of social species. However, some experimental procedures dictate that laboratory animals are housed individually. There is evidence to suggest that, by mimicking social contact, mirrors are beneficial to...

The effects of four types of enrichment on feather-pecking behaviour in laying hens housed in barren environments

Severe feather pecking, a potentially stereotypic behaviour in chickens (Gallus gallus), can be reduced by providing enrichment. However, there is little comparative information available on the effectiveness of different types of enrichment. Providing forages to birds is likely to decrease...

Solid floors versus wire floor housing for rats revisited: Influence of age and the presence of test boxes

Data did not reveal a clear preference for solid floors. Juveniles were found most often on wire floors while among adults, a preference for solid floors was apparent only in females, and only when a nest box was available.

Clinical pathology and cardiovascular parameters are not influenced by housing rats under increased environmental complexity

Since the release of the revised Appendix A from the Council of Europe for housing of laboratory animals there have been claims that laboratory animals should be housed under more complex conditions; known popularly as enrichment. A number of studies...
