Six adult female stumptailed macaques (Macaca aretoides) were trained within a two week period to actively co-operate during in-homecage venipuncture rather than in a restraint apparatus away from the homecage. The training was based on...
Compatible companionship has a therapeutic effect on behavioral disorders, providing long- term stimulation of a great variety of species-typical social behavior patterns. Inanimate objects have little impact on behavioral disorders, but some of them provide...
Simple technical improvements of three common deficiencies of macaque cages are described: a) dark lower row cages, b) inaccessibility of vertical space, c) lack of privacy.
The environmental enrichment program of the Caribbean Primate Research Center is guided by an evolutionary and ecological perspective. The evolutionary perspective suggests that primates should be housed in enclosures that provide a social and physical...
Animals living in upper-row cages were more active and engaged in more close contact amicable behavior than animals living in lower-row cages. Those located in the half of the room nearer the window were more...
New techniques were developed to avoid the manual transfer - and the associated health hazard - of caged macaques during handling procedures.
Authors describe the "Wellness Program" of the Primate Foundation of Arizona (PFA) devoted to producing physically and behaviorally normal chimpanzees. Psychological well-being is a major focus. In this paper, the authors present protocols specific to...
A semi-natural habitat that was designed to house a group of squirrel monkeys is described. Animals maintained in this environment were healthy, and none of the animals exhibited locomotor stereotypies. This facility was easier and...
Ordinary feeder-boxes were converted into food puzzles by remounting them onto the mesh of the front of the cages, away from original access holes. The total amount of time [pair-housed] adult male rhesus macaques engaged...
An attempt was made to encourage more foraging behaviour in eight pair-housed adult rhesus macaques (Macaca mulatta). No special device and no special food were used. Daily commercial dry food rations consisting of 33 bar-shaped...
