Behavioral effects of enrichment caging on a cynomolgus colony

Due to the aggressive nature of these animals [male cynos], use of new cohousing paradigms was not an option, and alternate methods for environmental enrichment were explored. ... We purchased three folding mobile-enrichment pens, each providing 24 ft2 of floor...

Group formation of a captive all-male group of lion-tailed macaques (Macaca silenus)

The [6 adult (5 years and older)] individuals were brought together simultaneously. .. .. The individuals showed no fights or other serious aggression during the first encounter on the first day. Aggression rates were high only during the first hour...

Pairing successes with male cynomolgus macaques after vasectomy

Problem: Traumatism, self-traumatism and better environmental enrichment of singly housed Male Cynos in our colony of approximately 100 Cynos.We also encountered incidents of aggressive behavior towards caretakers and stereotypical behaviors such as overgrooming.Approach: In our primate environmental enrichment program, we...

Conflict resolution following aggression in gregarious animals: a predictive framework

Knowledge of how animals manage their conflicts is critical for understanding the dynamics of social systems. During the last two decades research on gregarious animals, especially primates, has focused on the mechanisms of conflict management, mainly on friendly postconflict reunions...

Rearing and housing history of rhesus macaques (Macaca mulatta) displaying self-injurious and noninjurious abnormal behaviors

Postponement of initial single-housing, at least through the juvenile period, and restricting the duration of single-housing may exert a protective effect against abnormal behaviors, or may reduce the severity of the pathologies that develop.

Postconflict third-party affiliation in stumptailed macaques

Stumptailed macaques,Macaca arctoides, are characterized by high levels of postconflict affiliative contacts between opponents. We investigated the occurrence of postconflict affiliative contacts between opponents and third parties that were not involved in the original conflict. We collected 10-min focal observations...

Factors predicting increased incidence of abnormal behavior in malepigtailed macaques

Abnormal behavior was unrelated to the subject's housing location (biocontainment vs. other facility) or invasiveness of research. Nursery-reared subjects displayed more abnormal behavior than mother-reared subjects. Across and within rearing categories, the proportion of the first 48 months of life...

Mirrors as enrichment for monkeys

We have a mirror for every single-cage, plus enough for at least one per pen in our group-housing facilities. Over 700 of our 950 monkeys now have access to a mirror (Bio-Serv, Monkey Shine Mirror). They have been hung for...

Novel and economical structural enrichment for a unique colony of group-housed macaques: Success and failures

Social enrichment provided by group mates seems to overwhelm the effects of inanimate enrichment. With this thought in mind, rather than provide traditional puzzle or chewing devices, we designed structural enrichment. Different levels of perching and visual barriers were installed....
