Includes structural, behavioral, food, and auditory enrichment.
In laboratories, mice are housed at 20-24 °C, which is below their lower critical temperature (≈30 °C). Thus, mice are potentially cold stressed, which can alter metabolism, immune function, and reproduction. These physiological changes reflect...
Cognitive enrichment, a special form of environmental enrichment, addresses the cognitive abilities of animals in captivity. Through cognitive interaction with the environment, the animals regain a certain control over their environment, and essential resources, such...
The effect of the provision of simple objects to stabled horses on their behaviour was investigated to determine whether these objects can affect horses' behaviour in a positive way and thus enrich their environment. A...
To promote the psychological well-being of captive non-human primates, facilities develop and implement an environmental enhancement plan (Animal Welfare Act, Section 3.81). Enrichment options described in the plan should be selected to demonstrably promote species-typical...
Reptiles and amphibians have been neglected in research on cognition, emotions, sociality, need for enriched and stimulating environments, and other topics that have been greatly emphasized in work on mammals and birds. This is also...
Xenopus are a hardy, long-lived, aquatic amphibian species which readily adapt to a captive environment. This characteristic makes Xenopus ideal for the laboratory, where they are used extensively in basic and biomedical research. Though husbandry...
The main objective of the program of research, of which this study is part, is to evaluate the housing and environmental enrichment for laboratory rabbits. The aim is to determine whether modifications to basic housing...
Individual ventilated cages (IVC) have recently been increasing in popularity. Based on the high rates of ventilation with IVCs, we developed 3 hypotheses: first, mice housed in IVCs experience significantly more cold-stress than mice housed...
Individual ventilated cages (IVC) are increasing in popularity. Although mice avoid IVC in preference testing, they show no aversion when provided additional nesting material or the cage is not ventilated. Given the high ventilation rate...
Multiple species, study protocols and user needs make it difficult to develop a one-size-fits-all approach to standardizing enrichment. Fortunately, it turns out that there is a very simple solution to the complex issue of getting...
