Environmental Enrichment

Assessment of the reinforcing potential of auditory enrichment in adult male rhesus macaques

Environmental enrichment is a concept that describes how the environment of captive animals can be changed for the benefit of the inhabitants. In 2000, Wright and colleagues suggested that tonal melodies form musical gestalts for monkeys, as they do for...

Manzanita wood: A sanitizable enrichment option for nonhuman primates

Wooden objects are often used as nonhuman primate enrichment to provide variety and novelty, promote exploratory behavior, and supply an outlet for curiosity. However, concerns have been raised regarding the ability to sanitize wood by using conventional cage-wash procedures. To...

Can regular access to floor pens affect caged rabbit behavior? American Association for Laboratory Animal Science [AALAS] Meeting Official Program, 615-616 (Abstract #PS43)

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 will improve the wellbeing of...

Biology, behavior, and environmental enrichment for the captive African clawed frog (Xenopus spp)

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 practices for Xenopus have not...

Environmental enrichment and cognitive complexity in reptiles and amphibians: Concepts, review, and implications for captive populations

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 evident in the historic lack...

Enrichment object preferences in laboratory rhesus monkeys (Macaca mulatta)

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 behaviors. Too often, enrichment choices...

The enriching effect of non-commercial items in stabled horses

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 positive influence can for example...

Effects of cognitive enrichment on behavioural and physiological reactions of pigs

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 as food or water, act...

Impact of nesting material on mouse body temperature and physiology

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 impaired wellbeing, and affect scientific...

Effects of cage enrichment on heart rate, blood pressure, and activity of female Sprague-Dawley and spontaneously hypertensive rats at rest and after acute challenges

Here we sought to determine whether a nonsocial cage enrichment program, identical to one we previously used with male rats, was effective in reducing heart rate or systolic blood pressure (SBP) in female Sprague-Dawley rats and spontaneously hypertensive rats (SHR)....
