Multiple daily dosing regimens need not be a barrier to group housing of primates undergoing toxicology studies

It is demonstrated how same-sex group-housing of long-tailed macaques and regulatory toxicology are compatible.

The effects of cage size and complexity on the behaviour of captive common marmosets, Callithrix jacchus jacchus

Pair-housed marmosets showed a significant increase in perching plus a significant decrease in stereotypic and aggressive behavior several months after being transferred from their small home cages equipped with a nest box and two branches to double-size cages that were...

Hormonal response to restraint in rhesus monkeys

These experiments indicate clearly that placement in a restraining chair represents a stimulus of different systems in monkeys. The responses observed in the present study are predominantly psychoendocrine responses to unconditioned emotional stimuli associated with the chair-restraint situation, despite the...

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.
