【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。更多还原

【Abstract】 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 independent 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.更多还原
