Adult-adult social play in captive chimpanzees: Is it indicative of positive animal welfare?

Play is sometimes considered as an indicator of positive animal welfare. However, it is not yet sufficiently understood whether or not social play among adults can be considered as such an indicator because it is rare in adult animals. This...

Environmental enrichment in the 21st century

More than a quarter of a century has elapsed since the Animal Welfare Act mandated that research facilities develop and follow a plan to promote the psychological well-being of captive primates. Since passage of this law, considerable effort and resources...

Stone handling, an object play behaviour in macaques: Welfare and neurological health implications of a bio-culturally driven tradition

Object play in primates is viewed as generally having no immediate functional purpose, limited for the most part to immature individuals. At the proximate level, the occurrence of object play in immatures is regarded as being intrinsically self-rewarding, with the...

Non-human primate housing facility at Newcastle University

Monkeys first arrived in the Comparative Biology Centre (CBC) at Newcastle University in 2000. They were housed in three small separate units consisting of steel and wooden cages. In 2011 a decision was made to centralise the NHP facilities as...

Innovative enrichment for the common marmoset (Callithrix jacchus)

As part of the enrichment programme at King's College London (KCL) and in keeping with the guidelines of Animals (Scientific Procedures) Act, 1986 (ASPA) and the 3R's (Russell and Burch), technologists have taken an active role in designing innovative and...

Cooked food for non-human primates: A discussion by the Laboratory Animal Refinement & Enrichment Forum

"Do any of you give cooked food like pasta, potatoes or vegetables to non-human primates? What's your experience? Do the animals benefit from cooked food; do they like it; does it affect their health in any way? Do you add...

Hair plucking, stress, and urinary cortisol among captive bonobos (Pan paniscus)

Hair plucking has been observed in many captive primate species, including the great apes; however, the etiology of this behavioral pattern is poorly understood. While this behavior has not been reported in wild apes, an ethologically identical behavior in humans,...

Behavioral research as physical enrichment for captive chimpanzees

In this study, we evaluated the potential for a behavioral research study, designed to evaluate chimpanzee decision‐making behavior, to also encourage increased activity in a group of zoo‐housed chimpanzees. For the behavioral study, the chimpanzees had to carry tokens to...

Blunting/cutting canines of adult male monkeys: A discussion by the Laboratory Animal Refinement & Enrichment Forum

"When you keep adult Rhesus macaque (Macaca mulatta) males, adult Cynomolgus (Macaca fascicularis) males or adult Vervet males (Chlorocebus pygerythrus), in the same enclosure, is it advisable to have the canines of the males blunted or cut?" - question posed...

Measuring physiological stress in the common marmoset (Callithrix jacchus): Validation of a salivary cortisol collection and assay technique

Cortisol levels are often used as a physiological measure of the stress response in captive primates, with noninvasive measures of this being an important step in welfare assessment. We report a method of collecting saliva samples voluntarily from unrestrained captive...
