Grooming-contact bars provide social contact for individually caged laboratory primates

We investigated pair housing of adult long-tailed macaques (Macaca fascicularis) by using widely spaced, vertical "grooming-contact" (G-C) bars that allow physical contact but prevent pursuit by one animal into the other's cage. Cages with G-C bars provide several potential advantages...

The integration of stranger males into a group of tufted capuchin monkeys (Cebus apella)

The introductions were noteworthy for their early lack of both aggression and affiliation. Unlike the macaque model, in which aggression occurs immediately and relationships are settled quickly, the social integration of male capuchins was a gradual process.

The application, use, and effects of training and enrichment variables with Japanese snow macaques (Macaca fuscata) at the Central Park Wildlife Center

A training protocol is briefly described which allows the keepers through vocal and visual cues to herd the animals to a holding area. Training sessions were deterring stereotypic and abnormal behaviour - such as excessive grooming and fur-pulling. A feeding...

A-mazing orangutans

A food puzzle was constructed and modified several times to take into account the subject's high level of intelligence. The results were everything I could have hoped for. Not only did he maneuver the [food] items through the maze, he...

Sociophysiological aspects of short-term separation in common marmosets (Callithrix jacchus)The Housing of Non-Human Primates Used for Experimental Research and Other Scientific Purposes: Issues for Consideration

The results show that separation in combination with a transfer to an unfamiliar cage constitutes a particularly stressful event. A familiar environment can clearly reduce the stress of a separation.

Behavioral enrichment for captive cotton-top tamarins (Saguinus oedipus) through novel presentation of diet*

This case study suggests that novel presentation of diet could be a strategy of behavioral enrichment for tamarins in general, potentially modifying their behavioral patterns and use of enclosure space. .. Almost all enrichment trials produced the desired effect of...

Resocialisation of rhesus macaquesThe Housing of Non-Human Primates Used for Experimental Research and Other Scientific Purposes: Issues for Consideration

The new legislation on housing and husbandry of non-human primates forces research institutes to house formerly single caged experimental animals in social groups. Due to the poor ethological expertise in medical research centres and because singly housed experimental animals lack...

Rhesus monkey behaviour under diverse population densities: coping with long-term crowding

A popular view is that high population density promotes behavioural pathology, particularly increased aggression. In contrast, according to a coping model, some primates have behavioural mechanisms (e.g. formal displays, reconciliation and grooming) that regulate social tensions and control the negative...

Two species of macaques (M. mulatta and M. fascicularis) have been used for several decades in biomedical research at the University of Uppsala, Sweden. The monkeys were previously housed in single cages and enrichment routines were not ordinarily used. Infants...
