Environmental Enrichment

Assessing the application of the 3Rs: A survey among animal welfare officers in The Netherlands

Implementation of the 3Rs (Replacement, Refinement and Reduction) in animal studies is a legal requirement in many countries. In The Netherlands, animal welfare officers (AWOs) are appointed to monitor the welfare of laboratory animals. As part of this task, AWOs...

Reaction to novel pool enrichment by indoor group-housed juvenile Macaca nemestrina

Environmental enrichment is provided to laboratory-housed nonhuman primates to encourage species-typical behaviors. Some enrichment is labor intensive so quantitative studies should be undertaken to assure that the benefit is worth the effort expended. This study examined the effect of water...

Increased produce enrichment reduces alopecia in captive outdoor socially-housed rhesus macaques (Macaca mulatta)

Alopecia is relatively rare in wild primates but more frequent in captive settings. We investigate whether increasing the quantity and variety of produce enrichment reduces alopecia. Alopecia was scored bimonthly from September 2011 through mid-November 2012 for eight social groups...

Play caging benefits the behavior of singly housed laboratory rhesus macaques (Macaca mulatta)

This study addresses a recommendation in The Guide for the Care and Use of Laboratory Animals to provide singly housed nonhuman primates with intermittent access to large, enriched (play) caging. Research on the potential benefits of this type of caging...

The relationship between environmental enrichment, temperament, and stereotypy in captive rhesus macaques (Macaca mulatta)

Stereotypic behaviors are common in captive primate colonies, and it would be beneficial to know effective methods of remediation, and which animals are most likely to express the behavior. The first goal of this research was to determine the relationship...

The effects of music on animal physiology, behavior and welfare

Physiological and psychological effects of listening to music have been documented in humans. The changes in physiology, cognition and brain chemistry and morphology induced by music have been studied in animal models, providing evidence that music may affect animals similarly...

Novel enrichment item for non-human primates

Wheat grass kits are available from multiple sources (e.g. wheatgrasskits.com) and usually come with enough seeds and other materials to grow 5 flats. The instructions are very simple and the grass grows quickly, only taking about a week to reach...
