Captive rhesus macaques are not intrinsically aggressive, but poor husbandry and handling practices can trigger their aggression towards conspecifics and towards the human handler. The statement 'rhesus macaques are so aggressive animals' is probably based...
Using positive reinforcement, J. McKinley trained 12 common marmosets (Callithrix jacchus) to provide urine samples on request. The study then exposed the marmosets to mildly stressful, routine husbandry procedures (i.e., capture and weighing). The nonhuman...
Expanding on the National Research Council’s Guide for the Care and Use of Laboratory Animals, this book deals specifically with mammals in neuroscience and behavioral research laboratories. It offers flexible guidelines for the care of...
The USDA regulations pertaining to the minimum space requirements of nonhuman primates and the fitting of elevated resting surfaces are contradictory. They implicitly condone the prevailing perch design that allows maximal usage of animal room...
12 adult pair-housed female, 5 adult single-housed male and 10 adult pair-housed male rhesus macaques, and 6 adult pair-housed female stump-tailed macaques were trained to cooperate during in-homecage blood collection. The total number of training...
Federal welfare regulations for primates kept in research laboratories fail (1) to include recommendations pertaining to the legal requirement of the avoidance of stress and unnecessary discomfort during handling procedures, (2) to specify how the...
Many aspects of the research animal's housing environment are controlled for quality and/or standardization. Of recent interest is the potential for environmental enrichment to have unexpected consequences such as unintended harm to the animal, or...
The current status of the behavioral management of chimpanzees housed in US research facilities is examined, and recent advances are described. Behavioral management includes the application of environmental enrichment, animal training, and environmental design for...
Experiences with the pole-and-collar training training are shared. Yes, most monkeys can be trained but some cannot, or let's say they should not be trained because their personality -- which is presumably conditioned through negative...
