Environmental enrichment program for caged stump-tailed macaques (Macaca arctoides)

An effective social and inanimate enrichment program for caged stump-tailed macaques is described. Paired companions interacted with each other 22% of the time, they used the PVC perch 4.2% of the time, and the gnawing stick 5.7% of them time.

Evaluating the effectiveness of environmental enrichment

Taking the absence of behavioral disorders as a criterion for the effectiveness of an environmental enrichment strategy .. is therefore unrealistic. ... An environmental enrichment strategy is ineffective if it does not promote the expression of species-typical behavior patterns in...

Comparing the effectiveness of PVC perches versus wooden perches as environmental enrichment objects for singly caged rhesus monkeys

One half of each cage was provided with a PVC pipe, the other with an oak branch. Both perches had the same diameter and were installed in the same manner. During one-hour observation sessions, single-caged subjects showed no clear preference...

Catching Individual Rhesus Monkeys Living in Captive Groups (Videotape With Commentary)

A simple capture-chute design is demonstrated. Using vocal commands, a single person swiftly catches all members of a trained rhesus breeding group one-by-one in a transport cage without causing any disturbance or stress.

Avoiding undue stress: Catching individual animals in groups of rhesus monkeys

Training technique is described. We have successfully trained two heterogeneous rhesus troops of 28 and 33 members. The catching procedure has become a routine that is no longer associated with excitation and distress. It is now possible for one experienced...

Environmental enrichment for marmosets

Marmosets are among the easiest of primates to provide with environmental enrichment. Like other higher primates, they need companionship, adequate space with incorporated complexity, some unpredictability in the environment, ways in which they can manipulate or control their environment.
