Behavioral responses of unrelated adult male rhesus monkeys familiarized and paired for the purpose of environmental enrichment

Potential companions were first given the opportunity to establish clear-cut rank relationships during a 5-day period of noncontact familiarization. Only then were they paired in a different double cage. Rank relationships were confirmed within the first 6 minutes after pairing...

Alternatives to single caging of rhesus monkeys

Single-housed rhesus macaques were transferred to permanent pair-housing arrangements. The present investigation also demonstrates that pairing caged rhesus monkeys with compatible conspecifics does not interfere with a number of common research protocols [e.g., headcap implantation, experimental surgery, blood collection]. Our...

Housing, Care and Psychological Wellbeing of Captive and Laboratory Primates: Preface

Introduction to a very helpful book. Nowhere in this book is it asserted that research with captive primates should not be done. Everywhere it is asserted that it should be done with care, respect, and humanity. A few would add,...

Compatible rhesus monkeys provide long-term stimulation for each other

The [12 pair-housed] rhesus monkeys in the present study distracted each other in species-typical ways on average 35% of the time, even though the companions had lived with each other continually for 2.5 years. Apparently, a compatible companion is a...

Effects of environmental impoverishment on the social behavior of marmosets (Callithrix jacchus)

Family groups of marmosets were moved from a greenhouse enclosure to caged environments of increasingly limited size and stimulation. Social behaviors such as approach, follow, play, and grooming declined substantially. ... Nonsocial behaviors such as scent marking and locomotion also...

A perch for primate squeeze cages

Modification of single squeeze-cages is described allowing the installation of a perch that does not interfere with the normal operation of the cage. The monkeys make use of their perch for feeding, grooming and sleeping for 30% to 95% of...

A room with a view for captive primates: Issues, goals, related research and strategies

Recent controversies have made medical researchers, too, aware of both ethical issues in the use of animals for research, and scientific questions about the appropriateness of using stressed animals as research subjects.

A simple transfer and chairing technique for nonhuman primates

Most animals will come to the front of the cage to have the leash attached without use of the squeeze mechanism once they are familiar with the daily routine. In fact, some monkeys will get in and out of the...
