We describe the relative growth in infant cynomolgus monkeys (Macaca fascicularis). The multivariate analyses using the principal component analysis and multivariate allometric analysis were applied to biometrical data of laboratory-bred cynomolgus monkeys aged from birth to 12 weeks. All the animals had been bred and reared under uniform environmental conditions at Tsukuba Primate Center for Medical Science, N. I. H., Japan. As the result of the principal component analysis, the cumulative contribution ratio of the 1st and 2nd principal components (PC1 and PC2) accounted for 88.2% and 85.7% in males and females, respectively. This indicates that the morphologic traits (15 traits) grow normally in size, but the analysis did not detect any differences in growth rate among the traits. So, the multivariate allometric analysis was applied to the same data. The traits concerning the face and truck showed relatively high growth rates compared to head breadth, whereas the limbs and arms grew slowly.
我们描述了食蟹猴幼猴的相对生长情况。使用主成分分析和多变量异速生长分析的多变量分析方法被应用于从出生到12周龄的实验室饲养食蟹猴的生物测量数据。所有动物均在日本筑波国立医科大学灵长类医学中心统一的环境条件下饲养和培育。主成分分析结果显示，第一和第二主成分（PC1和PC2）的累积贡献率在雄性和雌性中分别为88.2%和85.7%。这表明形态特征（15个特征）在大小上正常生长，但分析未检测到各特征间生长速率的差异。因此，对相同数据应用了多变量异速生长分析。与头宽相比，面部和躯干相关的特征显示出相对较高的生长速率，而四肢和手臂生长缓慢。
