Includes structural, behavioral, food, and auditory enrichment.
In this study artificial turf was used as the substrate for a particulate food given to the subjects as an environmental enrichment technique. When their cages were not enriched, eight single-caged subjects exhibited abnormal behaviors...
The author reviews improvements in the behavioral management of a colony of captive chimpanzees at the Southwest Foundation for Biomedical Research. Environmental enrichment techniques, such as providing increased opportunities for physical, sensory, and feeding stimulation...
The influence of an environmental enrichment feeding device (puzzle feeder), on activity and behaviour patterns of captive orang-utans, gorillas and chimpanzees was studied at London Zoo. General activity levels and behaviours directed towards the feeder...
No quantitative studies have focused on the properties of a mirror and its use as a social enrichment tool. We did an observation study, which included 239 12-minute sessions over a four month period to...
When forage materials [chicken scratch] are provided, bedding materials, such as straw or shredded newspaper, along with woodchips increase the amount of time the captive chimpanzee spends in search of forage materials. ... Whether this...
This study compared the effectiveness of kraft wrapping paper and rubber to as enrichment for 22 chimpanzees group-housed in conventional indoor/outdoor runs. Objects were tested separately during 67 hours of data collection using a group...
To promote the well-being of previously single-caged adult (older than 5 years) rhesus macaques (Macaca mulatta) and the quality of research done with them, the following environmental enhancement plan has been developed and implemented at...
The area covered by the floor was 3 times larger than that covered by elevated structures; nonetheless the animals were located significantly more often (89.8% of 108 scan samples) on elevated structures than on the...
Compatible companionship has a therapeutic effect on behavioral disorders, providing long- term stimulation of a great variety of species-typical social behavior patterns. Inanimate objects have little impact on behavioral disorders, but some of them provide...
The environmental enrichment program of the Caribbean Primate Research Center is guided by an evolutionary and ecological perspective. The evolutionary perspective suggests that primates should be housed in enclosures that provide a social and physical...
