Serum cortisol concentrations of single-housed and isosexually pair-housed adult rhesus macaques

Possible social distress was evaluated in 20 adult rhesus macaques housed in compatible isosexual pairs (5 female pairs, 5 male pairs) for the purpose of social environmental enrichment. Serum cortisol concentrations of paired animals were compared with serum cortisol concentrations...

Self-awareness in the gorilla Koko

Responses of an adult female gorilla (Koko) to her own mirror reflections are described, documented and analyzed. During every session, Koko frequently exhibited self-directed behaviors such as grooming her underarms and picking at her teeth with the aid of the...

Avoiding undue cortisol responses to venipuncture in adult male rhesus macaques

Six adult rhesus males were: a) habituated to actively cooperate during venipuncture away from the homecage in a treatment squeeze cage, and b) trained to actively cooperate during venipuncture in the homecage.The magnitude of cortisol increase was significant when the...

Normalizing laboratory-reared rhesus macaque (Macaca mulatta) behavior with exposure to complex outdoor enclosures

Young group-housed animals housed in the outdoor corncrib also showed a decline in self-oral behaviour which persisted even upon return to the laboratory environment.Abstract of this work has been published in:American Journal of Primatology 18: 158, 1989; Novak MA, O'Neill...

Training adult male rhesus monkeys to actively cooperate during in-homecage venipuncture

A training technique is described for ensuring the active cooperation of 10 pair-housed and 5 single-housed adult male rhesus monkeys during in-homecage venipuncture. Mean cumulative training time investment per male was 40 minutes. Once trained, all males cooperated during in-homecage...

Social enrichment for aged rhesus monkeys who have lived singly for many years

There is widespread concern that aged rhesus monkeys who have been housed singly for a long time would do better living alone than sharing a cage with a companion. Ten female and five male rhesus monkeys, 22 to 33 years...

Impact of venipuncture on physiological research conducted in conscious macaques

A survey of 397 publications dealing with macaques was conducted. Stress-sensitive physiological data collected during venipuncture were evaluated in 58 reports. Despite of the fact that venipuncture often is a stressful event for research animals, 81% of the studies did...
