Daily feeding enrichment for laboratory macaques: Inexpensive options

The feeding enrichment options described here are structural elements of the cage, redesigned in such a way that they serve as primary feeders for the daily biscuit ration. Therefore, no extra time is needed to clean them and to bait...

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...

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...

Maracas for Macaca? Evaluation of three potential enrichment objects in two species of zoo-housed macaques

One group each of Barbary macaques and stump-tailed macaques, both zoo-housed, received hard replica fruits in three experimental conditions: as empty (unresponsive) objects, as maracas that rattled when manipulated (simple responsive), and as objects from which food items could be...

Physiological correlates of self-injurious behavior in captive, socially-reared rhesus monkeys

This study examined the relationship between self-injurious behavior (SIB) in rhesus monkeys and several biological variables, including monoamine metabolites in cerebrospinal fluid (CSF) and circulating levels of ACTH, cortisol, and testosterone. Cisternal CSF and blood plasma samples were obtained from...

Effects of olfactory stimulation as environmental enrichment for adult cynomolgus monkeys

[Unspecified] test odours were transferred onto fleece squares. The results of this study suggests that odour is a weak stimulus for environmental enrichment of macaques.

Enrichment discussion: The sugar question

Jen, Cobie, and Brooke all agreed that corn on the cob(raw, whole, uncooked - no need to shuck!) is a great form of enrichment for macaques. ... Many do eat the outer husks. Our vet has said that they probably...

Reproductive performance of rhesus macaques (Macaca mulatta) in two outdoor housing conditions

We conclude that, for rhesus macaques, outdoor corral housing leads to better reproductive performance than does semi-sheltered gang housing, probably as a result of increased individual space and relaxation of intense social stressors.

Male pigtailed macaques neonatally separated from mothers for clinical reasons show increased abnormal behavior as adults

The proportion of the first 48 months of life spent singly housed was significantly related to abnormal behavior in maturity. It explained 12% of abnormal behavior in mother-reared animals, 42% in experimental-nursery-reared animals, and 55% in clinical-nursery-reared animals.
