Environment- and season-influenced alopecia in juvenile rhesus macaques

The juveniles who were transferred to individual indoor rooms recovered from alopecia and hair growth began withina week. Hence we concluded that hair losses in outside enclosures are due to environmental stress. .. To conclude, if macaques are to be...

Environmental Enrichment for Nonhuman Primates

This document outlines the Primate Environmental Enrichment Program (PEEP) developed for the University fo Michigan. The program is designed to promote the psychological well-being of nonhuman primates (NHP) used in research and to provide opportunities for NHPs to engage in...

Altered hypothalamic-pituitary-adrenocortical function in rhesus monkeys (Macaca mulatta) with self-injurious behavior

These findings suggest that SIB in socially reared monkeys is associated with complex changes in HPA axis function that are related to the expression of the pathology, i.e. self-directed biting, and to the recency of a wounding episode.

Enclosure use by aged squirrel monkeys (Saimiri sciureus)

A group of squirrel monkeys was translocated from an indoor exhibit to an outdoor enclosure. The monkeys were scored most often among the largest and highest branches in the tallest tree in the enclosure (17.7% ). Males were scored more...

Computer-assisted enrichment for zoo-housed orangutans (Pongo pygmaeus)

The study of environmental enrichment has identified a variety of effective forms of enrichment, but there are widespread problems associated with their use. Few forms of enrichment are cognitively challenging, and even the most effective often result in rapid habituation....

Quantitative data on training new world primates to urinate

This study assessed the effectiveness of operant conditioning in training three species of captive callitrichid primates (Leontopithecus rosalia, Callithrix geoffroyi, and Saguinus imperator) to urinate on demand...Training sessions (30 min each) were conducted at dawn thrice weekly during five consecutive...

Use of a shredded paper substrate to ameliorate abnormal self-directed behavior of a chimpanzee (Pan troglodytes)

Abnormal behavior in macaque monkeys has been associated with risk factors such as nursery rearing and single housing. However, less is known about the extent of, and risk factors for, abnormal behavior in baboons. The purpose of this study was...

Housing and stereotyped behaviour: Some observations from an indoor colony of vervet monkeys (Chlorocebus aethiops)

Adult females displaying stereotypies in single cages were exposed sequentially to a foraging log and an exercise cage, as well as cages of varying complexity and dimensions. In another study females and males housed single in the bottom row, and...

Laboratory routines cause animal stress

Based on a literature review the conclusion was drawn that routine handling, venipuncture, and orogastic gavage lead to elevations of heart rate, blood pressure, and glucocorticoid concentrations that persist for 30 to 60 min or more following the event, suggesting...
