Self-injurious behavior (SIB) occurs sporadically in 5% to 15% of captive nonhuman primates, with over-representation among males and those animals housed in single caging prior to adulthood. Though SIB may manifest as a range of...
This study compares the benefits between the two housing types by video recording 14 pairs of adult female Macaca fascicularis in four sequential housing phases following an ABBA design: baseline grooming-contact, full contact shortly after...
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...
Abnormal behavior in macaque monkeys has been associated with risk factors such as nursery rearing and single housing. However, less is known about the extent of, and risk factors for, abnormal behavior in baboons. The...
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...
Stress has been associated with adverse hematologic and physiologic consequences, including immunosuppression and an increased risk of cardiac disease. Aberrant platelet activation has been documented in humans exposed to mental stress, and activated platelets, as...
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...
In the last decade several surveys of primate care and training programs highlight a common theme; despite scientific evidence that animal training can be effective in reducing stress, increasing efficiency and improving veterinary care, animal...
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...
Providing social housing that mimics the species' natural group composition should be an aim for all captive environments. Aotus are nocturnal, monogamist primates whose offspring (both male and female) disperse at sexual maturity, living solitarily...
