Normal serum biochemical, hematological, and EKG parameters in anesthetized adult male Macaca fascicularis and Macaca arctoides

Author underscores undesirable variations in serum biochemical and hematological parameters in macaques and suggests that incongruities between values presented in different reports may be due to a variety of factors including the method of restraint during handling procedures.

Captive propagation of vervet monkeys (Cercopithecus aethiops) in harems

Animals were placed randomly in ten single-male harem groups with 5-10 females per enclosure. This resulted in considerable fighting among the females. Each group was gradually reduced over a one year period to 2-4 females with their young. ... Three...
