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...
As a global company, our institution made the decision to install European Union (EU) Appendix A-compliant nonhuman primate cages at one of its facilities. This investment represented a substantial evolution of standards commonly employed within...
There are potential advantages of housing primates in mixed species exhibits for both the visiting public and the primates themselves. If the primates naturally associate in the wild, it may be more educational and enjoyable...
Recently, I devised yet another way to use this fleece material to enhance the environments of our animals. To this end, I sought out a way to present food enrichment to our animals so that...
Although alopecia may arise from a variety of causes, it is often viewed as an indicator of impaired wellbeing, frequently becoming a focus of regulators or facility managers. However, the extent of alopecia in populations...
Positive reinforcement training relies on identifying an effective reinforcing consequence, often food, to be presented contingent on the performance of the desired behavior. Prior to training sessions, we used a multiple stimulus without replacement (MSWO)...
The pole and collar method enables safe transfer of a monkey from their home environment to a restraint chair without sedation. The ability to conduct procedures with a conscious and cooperative subject is cost effective...
The quality of human-animal interactions can be an indicator of well-being in laboratory primates and increased anxiety-related behavior, such as aggression, may compromise an animal’s ability to provide research outcomes reflective of normal function. The...
