摘要
对5只鬣羚幼仔(2♀3♂)在非麻醉状态下测量了体尺与体重,并进行了行为观察。鬣羚幼仔出生至50日龄体重、体长、后足长、肩高、胸围、耳长和尾长均随幼仔日龄增加呈增长趋势,日增重平均值0.24 kg,相对增长194%,生长系数为3.01,至50日龄时体重增长了2倍。观察发现,幼仔17日龄采食树叶,55日龄出现爬跨行为。研究结果显示,幼仔平均55日龄学习爬跨行为,为其自身独立生活与成年后的繁殖后代奠定了基础,因此在圈养条件下过早地隔离将不利于鬣羚饲养。5月龄时幼仔与母亲有争抢食物的行为,因而此时可将幼仔与母兽分开。
We measured the body length and weight of five serow （ Capricornis sumatraensis） kids （ 2 females and 3 males ） under non - narcotic condition and observed their activities. Body weight, body length, hindfoot length, shoulder height, waistline, ear length and tail length increased gradually, with increasing age from 0 to 50 days of age. The average daily weight gain was 0. 24 kg with a relative increase 194% and growth coefficient 3.01. Body weight increased 3 times at 50 days of age. Kids began to eat leaves at 17 days of age and mounting behaviors occurred at 55 days of age, which settled foundation for inde- pendent living and reproduction as adults, so it is not beneficial for feeding if kids are separated from adults too early. Kids fought with their mothers for feed at 5 - month of age, so this is the appropriate age to separate kids from their mothers.
