Environmental Enrichment

Enrichment options: Rotating logs for great apes

The logs are fixed as far outside the ceiling fence as they only can be reached with selected branches provided by the keepers. Using these sticks, the apes have to bring the log out of equilibrium and turn the log...

Monkeys on ice

I spent an hour or so shoveling fresh, clean new snow into a huge plastic bin and dumped the lot on the floors of each small primate and prosimian indoor enclosure... The event was a tremendous success

A garden of enrichment

The animals are spending a lot of time searching for different species of plants, not only because of their medicinal compounds but also because of their taste. Both seeking out and eating the herbs can occupy a lot of the...

Enrichment options: Food pods and mesh feeders

Food pods are a recent innovation and are constructed primarily of PVC tubing whish, in turn, is fastened to nets or firehose. The object is to extract foods which have been placed in the tubes via internalized, gorilla-proof, access seals....

Effects of environmental enrichment on behaviour and reproductivity of growing pigs

Enriching the environment [extra area with peat and a straw hopper; pigs in enriched environments had more than four times the floor space of pigs in barren environments] reduced both the amount of time pigs spent inactive and the time...

A comparative analysis of the effects of behavioral enrichment and the utilization of tools within and between captive groups of western lowland gorillas (Gorilla gorilla gorilla) and Bornean orangutans (Pongo pygmaeus pygmaeus)

Unspecified enrichment items are tested. Abstract of this work has also been published in: American Journal of Primatology 33: 252-253, 1994; Wright BW; The effects of behavioral enrichment and the utilization of tools within and between captive groups of western...

Effects of environmental enrichment on nonsocial and abnormal behavior of captive lowland gorillas (Gorilla gorilla gorilla)

The use of straw as bedding material appears to have a positive effect on both specific nonsocial [feeding/foraging] and abnormal behavior [coprophagy, regurgitation].

Improving the laboratory environment for nonhuman primates

Environmental improvements include construction of large indoor cages that allow pairing of experimental animals, a grass-covered 'playground' for breeding chimpanzee groups, and indoor/outdoor group housing for 'retired' experimental animals. In addition, we provide toys, perches, mirrors, and foraging devices, and...
