Predictors of social status in cynomolgus monkeys (Macaca fascicularis) after group formation

The purpose of the present study was to determine whether various behavioral and hormonal markers obtained in individually housed monkeys would be predictive of social rank following group housing. Body weight, serum cortisol and testosterone levels, and locomotor activity in...

Pair-formation protocol for adult, previously single-caged macaques: Minimizing risks

This is a systematic method of introducing two adult macaques in a way that minimizes risks - and lets the monkeys have some control over the process.The alternative method of simply introducing unfamiliar animals into one cage is ethically not...

Positive reinforcement training and group-housed rhesus macaques: A look at training time investment and the potential benefits

Several groups of rhesus macaques with five to seven group members were trained .. to 1) go to the front of their enclosure, 2) go to a designated station area, and 3) touch a designated target. .. While the average...

Environmental enrichment for rhesus macaques: A cost-effective exercise cage

A movable exercise cage for rhesus macaques is described. Within our facility, increased visual attentiveness by other animals, decreased self-directed biting and hair picking, and improved food consumption was observed when rhesus macaques were permitted access to an exercise cage...

King Kong® rubber toys: An effective enrichment device for captive chimpanzees (Pan troglodytes)

Subjects were tested on one single occasion each when they had access to a toy for 15 minutes. High percentages of use by two chimpanzees adjacent to social groups suggest that the King Kong toy may be an especially effective...

Social awareness in monkeys

Tests of self-awareness in nonhuman primates have to date been concerned almost entirely with the recognition of an animal's reflection in a mirror. By contrast, we know much less about non-human primates' perception of their place within a social network,...

Videotape viewing as enrichment during recovery of hospitalized monkeys

During videotape exposure monkeys did not remove their sutures. Animals that had previously withdrawn from food were observed eating during videotapes showing primates eating.

The lower-row cage may be dark, but behavior does not appear to be affected

The situation of 3 upper-row single-caged females was compared with that of 6 lower-row single-caged females. Mean light levels at nine different positions within the cage were significantly lower in bottom-row cages than in upper-row cages. Not only did light...

A comparison of cell-mediated immune responses in rhesus macaques housed singly, in pairs, or in groups

The data demonstrate that social housing condition affects immune responses. While not unidirectional, these effects generally suggest enhanced immune responses for socially housed animals. .... It is our contention that strong social relationships, particularly the affiliative interactions that characterize our...
