Environmental Enrichment

Modification of fear in domestic chicks, Gallus gallus domesticus, via regular handling and early environmental enrichment

Regular gentle handling and environmental enrichment reduced fear responses to people. The implications of reduced fearfulness and other potential benefits of handling and enrichment procedures are discussed.

Alternative forage types for captive chimpanzees

Chicken scratch, because it is small and harder to find [in the litter], elicited the most foraging of the three foods ['sweet feed', popcorn]. It is very encouraging to see the chimpanzees still foraging late in the day for these...

The effects of food treat provisioning and human interaction on the behavioral well-being of rhesus monkeys (Macaca mulatta)

The effects of human interaction and food supplementation appear to be protracted, resulting in a reduction of behavioral disorders even after the enrichment is removed.

Assessing the cost-effectiveness of specific enrichment items for captive chimpanzees

The results show that the raisin blocks and the probing boards stimulated the most activity, followed in descending order by browse and burlap, boxes and seeds. ... Adult chimpanzees engaged in foraging behaviours, but rarely did they interact with the...

Sensory approach to enrichment design increases use of cage space and activity in research monkeys

The box was affixed to the cage top. Food items, colorful toy objects, and paper and cedar chips, were placed in the box. No data are included in this abstract.

Pickle barrels as enrichment objects for rhesus macaques

Barrels were arranged three ways: unattached, on a swivel, and stationary. ...Barrels were not used by all [group-housed] animal classes, adults virtually ignored them.

Mirrors as enrichment for the captive chimpanzee (Pan troglodytes)

No quantitative studies have focused on the properties of a mirror and its use as a social enrichment tool. We did an observation study, which included 239 12-minute sessions over a four month period to test the enrichment properties of...
