Techniques for collecting saliva from awake, unrestrained, adult monkeys for cortisol assay

Cortisol levels serve as an index of pituitary-adrenal activity in nonhuman primates. In adult monkeys, cortisol is normally measured in blood (typically requiring restraint or sedation) or urine (reflecting a state rather than point estimate). In contrast, saliva collection is...

Positive reinforcement training paired with videotape exposure decreases training time investment for a complicated task in female chimpanzees

Subjects were 10 adult chimpanzees living in two groups. Five females were exposed to a 10-minute videotape of female chimpanzees being positively reinforced for successfully urinating into a cup. Immediately following videotape exposure, these subjects participated in a training session....

A novel approach for documenting and evaluation of environmental enrichment programs

Eleven Aotus monkeys were videotaped using infrared sensitive cameras for a five-hour period on six nights. An ethological analysis software program was used to score the videotapes and to determine the frequency and duration of 17 activities. It was concluded...

Validation program for nonhuman primate enrichment devices ensures effective sanitation

A validation program was designed to assess the effectiveness of mechanical equipment or manual procedures and chemical disinfectants to sanitize a variety of enrichment devices. It was concluded that such a program can aid in prevention of disease transmission between...

Naive chimpanzees’ (Pan troglodytes) observation of experienced conspecifics in a tool-using task

The authors investigated the occurrence of naive chimpanzees' (Pan troglodytes) spontaneous observation of experienced conspecifics during a tool-use task entailing honey fishing. The chimpanzees were presented with 20 kinds of tools of which 12 kinds were usable. Six pairs of...

Enrichment device use by baboons during long-term vs. intermittent availability

Four of the six baboons increased their [cherry] log use over the exposure period [104 days], while the remaining two baboons decreased their interactions with their logs over this period. ...When the logs were available only every other day, or...

A novel approach to group-housing male cynomolgus macaques in a pharmaceutical environment

Twenty percent of our primates are maintained in a single-housed environment. Of those single-housed animals, 40% exhibited moderate to marked degrees of self-directed activity; i. e., hairpulling. By contrast, none of the pair or group-housed animals exhibited these behaviors. Our...
