Environmental Enrichment

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...

Environmental enrichment objects and singly housed rhesus monkeys: Individual preferences and the restoration of novelty

We found that the extent of physical contact with the [Kong toy, Nylabone ring and Nylabone ball] toys habituated during a short time. ... The introduction of a different toy every Monday was accompanied by a restoration of the apparent...

Puzzle feeder for great apes

The apes could manipulate food items to the end of the pipe by poking sticks through the 2 cm diameter holes drilled along the side of the pipe facing them. When the food items reached the end of the pipe,...

Enrichment devices for nonhuman primates

We will describe [and discuss] a number of different classes of enrichment devices that have been used at our institution or at other primate facilities. ... Sanitation is probably the most time-consuming aspect of enrichment.

Technical note: A primatrail or an inexpensive cage expansion for group housing small primates

An inexpensive method for converting standard laboratory cages into colony units for housing small primate species is described. In addition to increasing the volume of space available to the animals, this system also provides a complex of climbing, running, jumping,...

The use of artificial turf as a foraging substrate for individually housed rhesus monkeys (Macaca mulatta)

In this study artificial turf was used as the substrate for a particulate food given to the subjects as an environmental enrichment technique. When their cages were not enriched, eight single-caged subjects exhibited abnormal behaviors approximately 37% of the time....
