Differences in housing location and the amount of room disturbance associated with blood sampling have a significant impact on cell counts, but not on ACTH or cortisol levels. We believe that the critical factor that...
Eight baboon groups (Papio sp.) were observed for over one hundred scan samples both before and after the provision of structural enrichment. Additions to their home-cage included a galvanized ladder suspended horizontally by chains and...
Cage space requirements for non-human primates in the United States of America are less than those in European countries. Studies in support of the assumption that the US legal minimum cage size provides adequate space...
According to the Swiss Animal Welfare Legislation, the minimal enclosure area for macaques of the size of rhesus or cynomolgus monkeys for experimental purposes is 15 cubic meters. In such an enclosure up to 5...
Caretakers should seek knowledge of the natural lifestyles of the primates in their charge, and attempt to reproduce in the captive environment the salient aspects of the natural habitats that are biologically relevant to the...
The purpose of this study is to consider space use patterns of a single group of captive chimpanzees (Pan troglodytes) housed in an indoor exhibit at the Cleveland Metroparks Zoo. This report summarizes results from...
Practical recommendations to address five basic characteristics of Old World primates in the laboratory setting: a) social disposition, b) semi-arboreal lifestyle, c) complex living environment, d) intelligence, e) sensitivity to distress.
The purpose of this study was to link abnormal behaviors often expressed by chimpanzees living in captive environments to factors related to their care and housing. Individuals who had spent more time with their mothers...
The objective of toxicology and pharmacology studies is to detect change or variation from normal and to interpret the significance of such change, with the intention of assessing risk to man. With non-human primates (NHPs)...
