Abstract
From February 1972 to August 1974 ten immatureCebus albifrons monkeys were weighed and vaginal swabbing performed at monthly or shorter intervals to determine age and weight at the onset of puberty. The average weight (±S.E.M.) at birth and at puberty was 226±5.8 g and 1,617±32.45 g, respectively. The average age at puberty was 3.59±0.17 years. The average weight velocity for all ten monkeys shows the maximum rate of weight gain to occur shortly after birth and decrease rapidly to its smallest prepubertal increment at nine months of age (weaning). From nine months there is a post-weaning weight spurt which reaches its greatest velocity at an average age of 15 months. Thereafter, the weight velocity decreases to its lowest level. Individual weight velocity curves of each of the ten animals show a slight prepubertal weight spurt which is not obvious in the average growth curve.
