Primate housing facilities for pharmaceutical research in Switzerland (an example)

According to the Swiss Animal Welfare Legislation, the minimal enclosure area for macaques of the size of rhesus or cynomolgus monkeys for experimental purposes is 15 cubic meters. In such an enclosure up to 5 adult animals may be kept...

The effects of different types of feeding enhancements on the behaviour of single-caged, yearling rhesus macaques

Enrichment techniques designed to encourage captive primates to spend more species-appropriate amounts of time in foraging behaviours have been successful. The present study measured the behavioural effects of four feeding enhancements: two devices (mats and puzzles) and two foods (produce...

Primate housing facilities for pharmaceutical research in SwitzerlandThe Housing of Non-Human Primates Used for Experimental Research and Other Scientific Purposes: Issues for Consideration

According to Swiss Animal Welfare Legislation primates should be housed in groups. The minimal enclosure area for macaques of the size of rhesus or cynomolgus monkeys for experimental purposes is 15 cubic meters (e.g. a floor area of about 8...

Primate displacement activities as an ethopharmacological model of anxiety

Using a within-subject cross-over, vehicle-controlled design, we investigated the acute effects of benzodiazepine receptor ligands with different mechanisms of action on the displacement activities (scratching, self-grooming, and body shake) of seven male macaques living in social groups. Our aim was...

Human interaction as enrichment for captive chimpanzees: A preliminary report

These results suggest that simple, unstructured affiliation between humans and chimpanzees has a powerful impact on well-being, promoting activity and relaxed conspecific interactions and ameliorating undesirable behaviors [e.g., abnormal behaviors].

Enrichment effects on rhesus monkeys successively housed singly, in pairs, and in groups

Subjects were more socially oriented when pair-housed than when living in small groups. Inanimate enrichment did not affect behavior ... although enhancements were well-used by singly-caged yearlings and pair-housed juveniles. Subjects used enrichment less frequently when housed in groups. The...

Straw and forage material ameliorate abnormal behaviors in adult chimpanzees

In an [successful] effort to reduce abnormal behaviors, especially regurgitation and reingestion, and promote higher activity levels [locomoting and playing], straw and scattered forage material were added to the enclosures of 13 indoor-housed chimpanzees living in pairs and trios.

What makes novel objects enriching? A comparison of the qualities of control and complexity

The overall picture from this experiment is that [group-housed] captive monkeys prefer responsive objects to unresponsive ones but have no preference for visual complexity over simplicity.

Behavioral indicators of anxiety: an empirical test in chimpanzees

Behavioural, pharmacological, and physiological evidence supports an association between displacement activities and anxiety in macaques. Information is scarce in other primate and non-primate species. This study contributes to the understanding of the relation between displacement activities and emotional states by...
