Auto-mutilation in animals and its relevance to self-injury in man

Self-mutilation in non-human mammals is a well-established, although not a widely known phenomenon, which has been reported under zoo and laboratory conditions. In macaque monkeys, laboratory rearing and isolation are important predisposing factors, and the more serious self-injury is initiated...

Some effects of living conditions upon the pattern of growth in stumptail macaque (Macaca arctoides)

Confinement and prolonged lack of physical exercise are very probably responsible for the reduced weight and size of our monkeys bred in laboratory conditions. ... This is apparently due to the impaired development and resulting athrophy of the muscles, particularly...

Woodchip litter in macaque groups

The effects of the presence of woodchips as a floor covering were assessed on psychological well-being in two pens housing 28 macaques. No negative effects were found, while aggression decreased and time foraging on the floor increased. The chips were...

The Stanford outdoor primate facility

Various inanimate enrichment options for outdoor-housed chimpanzees are described. An adolescent male chimpanzee cooperated in venipuncture; research assistants draw a 10-ml sample of blood while the animal sucks apple juice from a plastic bottle.

Environmental enrichment and behavioral engineering for captive primates

Food dispensing apparatuses were developed and successfully implemented as feeding enrichment options for group-housed gibbons, siamangs and diana monkeys. Frequently, often with free food in their hands, they [gibbons] attempted to get the lights and levers to respond and missed...
