| 摘 要： | 对上海动物园笼养羚牛种群20 a间的繁殖记录进行了统计分析,并将笼养羚牛和野生羚牛的各项繁殖指标进行了比较分析。结果表明：笼养条件下出生的雌性和雄性羚牛个体的首次成功繁殖年龄分别为4岁和5岁;笼养条件下出生的羚牛包括26只雌性和11只雄性,雌雄性比为2.36：1;羚牛的出生主要集中在1～4月,3月出生的个体最多;笼养羚牛首次繁殖年龄和幼仔出生季节与野生羚牛不存在显著差异。上述研究结果表明,影响羚牛繁殖的因素主要包括气候、环境、温度和湿度等。

| Abstract: | We analyzed breeding records of takin(Budorcas taxicolor) held in captivity at Shanghai Zoo over a period of 20 years.We compared these data with breeding records of wild takin.The earliest successful reproduction age in captive male takins was 5 years and for females 4 years.26 female and 11 male takin were born in captivity with a 2.36:1 sex ratio of females to males.Most of the takins were born in January to April,with a peak in March.There were no significant difference between captive and wild takin in... |
