Monthly blood samples were collected for more than two years from adult stumptail macaques living in a large captive group. The social organization, feeding pattern, and food composition were stable throughout the study period. No seasonal variability was observed for any of the 30 blood variables studied. It appeared that for each variable, within-animal variance was small relative to between-animal variance. A table of means and reference ranges is presented and discussed.
在两年多的时间里，每月从生活在一个大型圈养群体中的成年短尾猕猴身上采集血样。在整个研究期间，社会组织、进食模式和食物组成保持稳定。在所研究的30项血液变量中，未观察到任何季节性变化。似乎对于每个变量，动物个体内部的差异相对于动物个体之间的差异较小。给出并讨论了一份均值和参考范围表。
