黑叶猴齿序年龄与其身体生长的变化

The Change of the Presbytis Francoisi's Tooth-Age and Growth

用自繁育的黑叶猴作测定，结果表明：黑叶猴整个生长过程大致可分为缓慢生长期（初生至５月龄），生长旺盛期（６月至４岁１月龄），生长减慢期（４岁１月至４岁１０月龄以上）．各期身体生长的平均值在雌雄个体之间看不出有明显差异．

The results of the test with the self--bred presbytis francoisi show that the whole growth process of presbytis francoisi may be roughly divided into slow growth period (from the birth to the age of five months).the exuberant growth period(from thg age of six months to the age of four years and one month) and the retarding growth period (from the age of four years and one month to the age of four years and ten months over). thereIs no apparent difference of the average value of body growth periods between the male and the female presbytis francoisis.
