Sex differences in compatibility of pair-housed adult longtailed macaques

Prefamiliarized partners were paired without ascertaining that they had established their dominance-subordination relationship. Newly formed pairs were separated for 17 hours and subsequently reintroduced daily during a study period of 23 days. Under these extraordinary circumstances male/male pairs were less...

Challenging conventional wisdom for housing monkeys

Our research indicates that the minimum cage size does provide adequate space for the monkeys that we studied [adult long-tailed macaques of both sexes]. Our studies [with barren cages] also lead us to the conclusion that spending millions of dollars...

Reproductive performance in captive breeding groups of Macaca mulatta: Gang cages versus outdoor corrals

Overall, outdoor corral housed animals had higher reproductive performance in comparison to gang-cage housed animals (further analysis showed that this was not a result of differential age structures or virological status). We thought that this may be a result of...

Object manipulation in Lisbon Zoo chimpanzees: A contribution to the discussion of the psychological well-being in captive animals

The provision of manipulable objects [plastic bricks, items of clothing] led to a significant reduction of aggression, visitor-directed and self-directed behaviors and activity.

Behavioral changes in chimpanzees following a move to a larger facility

After the move to the larger, structurally enriched facility, there was an increase in activity, a decrease in stereotypical behaviour, and an increase in threat behavior.

Housing Husbandry and Welfare Provision for Animals Used in Toxicology Studies: Results of a UK Questionnaire on Current Practice (1994)

Behavioral abnormalities appeared to be more common in Old World primates than marmosets. This may have been due to the fact that they tend to be single-housed, as the site which group-housed their animals reported that the incidence of all...

An enriching approach to captive chimpanzee care

The social environment [which includes the care providers] is perhaps the most critical factor in chimpanzee well-being, more important even than designs of the living space.
