Enticing nonhuman primates to forage for their standard biscuit ration

Ordinary feeder-boxes were converted into food puzzles by remounting them onto the mesh of the front of the cages, away from original access holes. The total amount of time [pair-housed] adult male rhesus macaques engaged in gathering the standard biscuit...

Diving and underwater swimming as enrichment activities for captive rhesus macaques (Macaca mulatta)

In order to assess the environmental enrichment value of a small swimming pool for captive juvenile rhesus macaques (Macaca. mulatta), observations of social and individual behaviours were made during baseline and experimental (pool) conditions. When the pool was available there...

Behavioral effects of enrichment devices on laboratory primates with stereotypic and self-directed behavior

Single-caged long-tailed macaques showed a decrease in self-directed behavior, especially self-biting, floating limb, hair pulling, and excessive licking, when treats were in the feeder. Paradoxically, both pacing and rocking increased when treats were in the feeder. A temporary reduction in...

Incorporating environmental enrichment into behavioral research in captive chimpanzees, Pan troglodytes

The proximate goal of this project was to create an enrichment protocol designed to enhance the physical space and foraging opportunities ... by introducing a variety of novel food and non-food objects into the home cage.

Preference of Xenopus leavis for different housing conditions

In this study, the preference of X. laevis for different housing conditions were examined. X. laevis preferred dark backgrounds, a water temperature between 20C-22C and the deeper parts of the test basin. Red earthenware pipe was accepted as cover, but...

Effects of environmental enrichment on aggressive behavior, dominance hierarchies, and endocrine status in male DBA/2J mice

The provision of a horizontal labyrinth consisting of vertical dividers with only a few openings enhanced territorial tendencies in groups of male mice, leading to increased aggression. Findings suggest that keeping adult male mice in structured cages can result in...
