摘要
本文报道了对大规模繁殖的恒河猴仔猴进行人工离乳抚育的试验。1984—1988年共抚育仔猴578只,平均离乳龄为4个月,抚育一年的成活率为91.5％。抚育一年内死亡的仔猴中有61.8％发生在离乳后第一个月内,2月龄以下(≤60天)离乳的仔猴有20％死亡,2月龄以上离乳仔猴的死亡率为6.9％;64.7％的仔猴死于肺炎和肠道病。人工离乳的仔猴,雄性在10月龄前、雌猴在9月龄前具有较快的生长速度,体重增长的回归方程为:w=145.6t+403.5,w=144.2t+372。仔猴提前离乳,能提高母猴的生育力。
578 rhesus infants were separated from breeding females before mating season and were used for nursery rearing experiment at Xishuangbanna, Yunnan National Laboratory Primate Center of China (YNLPCC) during 1984-1988. The we-

aning age varies from 1 to 230 days after birth, with an average of 113 days. 91.5% of infants were survival in the first rearing year. In the infants died within the first rearing year, 61.8% of them occurred in the first month; the death rate of infants weaned age under two month old (≤60 days) was 20% and which of weaned age over two month old was 6.9%. 64.7% of death were resulted from pneumonia and enteropathics. The nursery-rearing infants of male under ten months of age and female under nine months of age have a rapid growth rate, their regressive equation on the growth of body weight (grams) are:
W = 145.6t + 403.5 (male, under 10 months of age)
W = 144.2t + 372 (female, under 9 months of age)
We believe that separating infants from their mothers before mating season could improved female fertility.
