Includes structural, behavioral, food, and auditory enrichment.
Group housing [female] guinea pigs can save space and money, while improving housing standards. The authors describe enclosure design, enrichments, and husbandry techniques that facilitate group housing female guinea pigs. No data are included in...
The chimpanzees are fascinated with the bubbles floating .... run around sticking out their tongues, much as a child collecting snowflakes, and attempting to catch them - a bit bewildered as it disappears.
At the Primate Foundation of Arizona (PFA), we provide many different types of both destructible and indestructible objects, but seldom provide rigid plastic balls. They are frequently thrown about the enclosure during displays and have...
Subjects were tested on one single occasion each when they had access to a toy for 15 minutes. High percentages of use by two chimpanzees adjacent to social groups suggest that the King Kong toy...
Both pigs and rabbits are having a great time banging the bone on the cage - they can swing it around, and they get to chew on it too!
In the social condition, the animals tended to show an increased heart rate, presumably resulting from competion over access to the foraging device.
General discussion of environmental enrichment. Many laboratory animal species, especially dogs and nonhuman primates, lose interest and stop using a particular device after exposure to it for some time (authors' experiences). It is best to...
Neonatal (early) handling (EH) and environmental enrichment (EE) of laboratory rodents have been the two most commonly used methods of providing supplementary environmental stimulation in order to study behavioral and neurobiological plasticity. A large body...
The enrichment of the animals' environment will not likely affect the interpretation of the results, particularly if adequate controls are used. Appropriate enrichment methods can be chosen to be compatible with the aims of the...
We have reviewed 40 studies carried out between 1987 and 2000, in which preferences as well as the effect of housing modifications have been studied. Mice will work for access to nesting material and make...
