A survey of 75 biomedical articles dealing with stress-dependent blood parameters in caged primates revealed that the conditions under which blood collection occurred were in most cases [72%] described either not at all or so...
A major focus of this paper is an examination of the complementary role that behavioral management strategies play in the establishment and enhancement of well-defined nonhuman primate research resources. .... Additionally, I will discuss the...
Their tendency toward natural behavior is probably little changed from their wild counterparts, despite the overwhelming influence of captivity on behavior... From a chimpanzee's point of view, it would be better to stimulate behavior characteristics...
In the social condition, the animals tended to show an increased heart rate, presumably resulting from competion over access to the foraging device.
The prevailing housing and handling conditions of monkeys in research institutions is described. The present situation in primate research laboratories strongly suggests that professional judgment is no guarantee that the inhumane housing and handling conditions...
In the United States, there are an estimated 15,000 individually caged macaques. If 10% of these animals exhibit visible injuries resulting from self-biting and another 10% show unnoticed self-biting behavior, then about 3,000 animals (20%)...
The perceived benefits of permanent, pre-weaning mother-infant separation are not supported by scientific findings. ... As long as there is an excessive number of monkeys and insufficient cage space, there is no ethically legitimate reason...
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...
