Abstract
To clarify the influence of rearing conditions on the growth of various bod y parts of Japanese macaques (Macaca fuscata), two groups reared under diff erent conditions, i.e., a group born and reared in open enclosures (Enclosu re group) and another consisting of macaques born and reared in cages (Cage d group), wire somatometrically analyzed. Somatometric data on 36 measures of various body parts were collected from 77 males and 92 females. Growth i n many body parts was smaller in the Caged group than in the Enclosure roup . Body parts that exhibited large incremental increases were more sensitive to differences in rearing space at the infantile growth stage in both sexe s. Recovery from delayed growth at the pubertal growth stage was found in m any body parts. However, the size of some locomotor elements such as the wr ist and hand, and ankle and foot strongly reflected limitations of space an d changes due to this were irreversible. Females wire more sensitive than m ales to such differences in rearing conditions, We conclude that open enclo sures with ample rearing space are necessary for the innate growth of Japan ese macaques to occur.
