Postnatal development in known-age captive orangutans was studied by collating new data from seven orangutans at Chicago Zoological Park, Brookfield, Illinois, with published and unpublished data from 76 additional captive orangutans. Norms were tabulated for deciduous and permanent dental emergence. Growth curves for weight and linear dimensions in females and males were compared in captive-reared and wild-reared subjects. Hand-reared and mother-nursed captives were compared with respect to dental emergence and weight increase. Differential relative growth of extremity segments was investigated. Pedigree data are presented relative to genetics of hallucal nail absence. Males of various ages were compared with respect to testis size and location and cheek-pad development.
已知年龄圈养猩猩的产后发育通过整合伊利诺伊州布鲁克菲尔德市芝加哥动物园的 7 只猩猩的新数据，与已发表和未发表的 76 只额外圈养猩猩的数据进行研究。记录了乳牙和恒牙的萌出数据。比较了圈养和野生环境下饲养的猩猩的体重和线性尺寸生长曲线。对人工喂养和母乳喂养的圈养猩猩在牙齿萌出和体重增加方面进行了比较。研究了肢体段的差异生长。根据跰甲缺失的遗传学，提供了系谱数据。比较了不同年龄的雄性在睾丸大小、位置和颊垫发育方面的差异。
