Includes structural, behavioral, food, and auditory enrichment.
The 3 enrichment devices had different effects on individual expression of stereotypy: supertubes decreased it, shakers increased it, and puzzle balls led to a decrease followed by an increase. We present potential reasons for the...
This study examined whether allowing 10 singly-housed adult male rhesus macaques (Macaca mulatta) 2-week access to a larger play cage would increase their species-typical behavior and decrease anxiety and abnormal behavior. The play cage consisted...
In this article, we address some of the issues surrounding the behavioural needs of captive animals and go on to elucidate some of the key aspects of the environmental enrichment strategy at Bioculture (Mauritius) (BCM)...
Wooden objects are often used as nonhuman primate enrichment to provide variety and novelty, promote exploratory behavior, and supply an outlet for curiosity. However, concerns have been raised regarding the ability to sanitize wood by...
Environmental enrichment is a concept that describes how the environment of captive animals can be changed for the benefit of the inhabitants. In 2000, Wright and colleagues suggested that tonal melodies form musical gestalts for...
Imagine if your everyday world was boring, blah and completely sterile looking with limited amounts of color. Unimaginable, right? Here at Legacy Schering Plough/Merck, we thought the same about our nonhuman primates who look at...
Three feeding enrichment treatments were tested in an outdoor yard used by six Western lowland gorillas (Gorilla gorilla gorilla). In "Yard-toss", forage was thrown by hand over one third of the yard. In "Set-up", forage...
European Directive 2010/63/EU requires that accommodation and care are refined so as to minimize suffering, and that the lifetime experience of the animal is taken into account when assessing the actual severity of procedures. So...
Xenopus laevis is the most widely used model amphibian species in laboratories, yet there is almost no experimental evidence to guide best practice for captive housing. Enrichment is an important component of maintenance and welfare...
Here we sought to determine whether a nonsocial cage enrichment program, identical to one we previously used with male rats, was effective in reducing heart rate or systolic blood pressure (SBP) in female Sprague-Dawley rats...
