The role of peers in modifying behavioral distress and pituitary-adrenal response to a novel environment in year-old rhesus monkeys

Infant rhesus macaques were captured from their social group and placed in an unfamiliar environment for 24 hours either (a) alone or (b) with another infant from the same group. When tested alone, the animals exhibited significantly more signs of...

Reduction of mortality due to fighting in a colony of rhesus monkeys (Macaca mulatta)

Mortality resulting from fighting [17 deaths per 100 females per year] in a breeding colony of rhesus monkeys living in groups was an important management problem. It was found that the cause of the fighting was the social disruption resulting...

Older monkeys’ (Macaca radiata) response to new group formation: Behavior, reproduction and mortality

Groups were formed without any preliminaries. Trauma did not play a role in the death [23%] of older [12-19 yrs of age] animals. A group of younger bonnets (5 males and 33 females under 10 yrs of age) suffered 11%...

Deep litter: Experiments with seven species of primates in Edinburgh Zoo

The presence of woodchip litter decreased inactivity and fighting in group-housed animals. With time, the litter became increasingly inhibitory to bacteria.

Ketamine-HC1 as a suitable anesthetic for endocrine, metabolic, and cardiovascular studies in Macaca fascicularis

Findings make it clear that ketamine itself is unlikely to affect stress-sensitive research data.

Self-aggressive behaviour in monkeys

Self-aggression is most often reported in some Old World monkeys that have been reared under conditions of social deprivation, and rarely occurs in the wild. It may also appear in normal animals under very stressful conditions. Self-aggression is more prominent...

Serum prolactin concentrations in mangabey (Cercocebus atys lunulatus) and patas (Erythrocebus patas) monkeys in response to stress, ketamine, TRH, sulpiride and levodopa

Injection of ketamine resulted in a significant increase in serum prolactin. The stress related to the i.m. injection itself could have been the cause of this increase.

Pituitary response to LRH and TRH stimulation and peripheral steroid hormones in conscious and anaesthetized adult male rhesus monkeys (Macaca mulatta)

Adult male rhesus monkeys are aggressive animals and very difficult to handle. Hence experimental manipulations necessarily involve the use of restraint procedures, either chemical or physical, which may influence endocrine functions. ... The male rhesus monkey, however, is a very...
