圈养赤大袋鼠繁殖及仔兽生长发育初探

open access: yes野生动物学报, 2018
从2014年7月到2017年7月,杭州动物园饲养的7只赤大袋鼠母兽,共繁殖了13只仔兽,7只存活,6只死亡。在此期间,从这7只母兽中选择3只进行育儿袋检查、育儿袋测温的行为训练,观察到1只仔兽的降生过程,对8只仔兽在育儿袋内的生长过程进行定时检查和拍照记录。结合另外3只母兽的繁育情况,对赤大袋鼠仔兽的生长发育特别是袋内的发育进行了初步的研究。对离袋的3仔兽进行测重行为训练,记录体重增长数据。结果发现育儿袋的温度在34.6~35.4 ℃,在圈养条件下仔兽开眼日龄在120~130 d ...

圈养大熊猫一年发情两次现象初探

open access: yes野生动物学报, 2019
大熊猫为季节性雌性单发情动物,发情期多集中在春季的3—5月,少数在其他月份,但都表现为1年发情1次。本文首次报道了成都大熊猫繁育研究基地4只雌性大熊猫1年内发情2次的异常现象并对此现象的原因进行了分析。同时,经过历年数据收集,发现这4只雌性大熊猫均未产仔,因此研究这样的异常发情行为可能对指导圈养大熊猫的饲养繁育工作具有一定的参考意义。
