Operant training of animals is a widely accepted practice to train or condition animals to cooperate with technical procedures or perform certain tasks in a laboratory setting. This type of training has been proven to...
Maintaining the psychologic wellbeing of nonhuman primates housed in a laboratory setting is an important aspect in providing the best possible care for these animals. Nonhuman primates kept in captivity can begin to display abnormal...
The ability to provide permanent group-housed caging for nonhuman primates involved in toxicology research is quickly becoming an important step in improving the overall quality of life for these animals. This type of caging offers...

Chimp Haven has retired 153 chimpanzees, the majority from biomedical research, and abnormal behavior patterns have been reported. Abnormal behaviors are well described in chimpanzees and usually related to early rearing environment, social isolation and...
Rhesus and cynomolgus macaques are some of the most frequently utilized laboratory nonhuman primates, and it is common for one facility to have a significantly large colony of either or both species. Daily care needs...
Juvenile cynomolgus monkeys are frequently used in drug pharmacokinetic and toxicology testing where they are cage housed for extendeded periods of time. In this study measures of body mass, bone metabolism, and turn over were...
Environmental enrichment of captive mammals has been steadily evolving over the past thirty years. For this process to continue, it is first necessary to define current enrichment practices and then identify the factors that limit...
The authors provided different forms of environmental enrichment to six old laboratory male tufted capuchin monkeys (Cebus apella) and studied the behavior of the monkeys during a baseline period and during three enrichment periods. Each...
