Growth of rhesus monkeys during the first 54 months of life

As part of a study of the long-term effects of environmental conditions on the health and development of non-human primates, the growth of 60 rhesus monkeys (Macaca mulatta, 34 males and 26 females) was determined longitudinally with biweekly or triweekly measurements of eight body dimensions from one to 54 months of age. Our data showed similar growth to previous studies and provide additional data defining normal rhesus monkey growth under more precisely defined living conditions than were reported in previously published studies on this species.
