Space utilization by captive-born baboons (Papio sp.) before and after provision of structural enrichment

Eight baboon groups (Papio sp.) were observed for over one hundred scan samples both before and after the provision of structural enrichment. Additions to their home-cage included a galvanized ladder suspended horizontally by chains and a plastic drum hung from...

Can natural plant growth provide a sustained environmental enrichment?

Since natural plant covers constantly change, they may provide a continuous environmental enrichment.

Enriching the behaviour of captive ruffed lemurs with a more naturalistic method of food presentation

By providing whole rather than chopped fruits, a greater range of postures and increased manual manipulation of dietary items could be obtained. Time spent feeding and foraging also increased significantly.

Influence of cage size and cage equipment on physiology and behavior of common marmosets (Callithrix jacchus)

The mean daytime heart rate increased with increasing cage size for the standard cages. This was expected because of the increased options for locomotor behavior.

Novel objects and learning as enrichment for captive common marmosets Callithrix jacchus jacchus

The studies have implications in the field of animal welfare in that they suggest that laboratory marmosets' behaviour can be enriched by giving the animals an opportunity to learn and to work for their food, and by rotating a set...

Correlates of self-injurious behavior in monkeys

Approximately 10% of captive, individually-housed monkeys engage in the disturbing phenomenon of self-injurious behavior. Self-biting males had been subjected to more frequent cage transfers than controls, suggesting that excessive disruption of daily routines may either cause or exacerbate self-injurious behavior.

Diarrhea and peritonitis due to traumatic perforation of the stomach in a rhesus macaque (hardware disease)

A cost-effective split level baboon condo

Two cages are connected by a latching mechanism. In addition to the increased square footage and the enriched cage environment, an unanticipated advantage is that we are able to place larger ancilliary enrichment devices into one of the cage units.
