Environmental Enrichment

Space utilization by captive rhesus macaques

The area covered by the floor was 3 times larger than that covered by elevated structures; nonetheless the animals were located significantly more often (89.8% of 108 scan samples) on elevated structures than on the floor (8.6% of 108 scan...

Bedding for enrichment

When forage materials [chicken scratch] are provided, bedding materials, such as straw or shredded newspaper, along with woodchips increase the amount of time the captive chimpanzee spends in search of forage materials. ... Whether this be the normal time for...

Physiology and environmental enrichment of rhesus monkeys on board the Space Shuttle

The two animals will be able to see each other through a transparent window. Video monitors which can be controlled using a joystick will serve as enrichment. Preliminary tests have shown that trained animals are able to feed themselves using...
