半野化环境下冒雨产仔 大熊猫“水秀”当妈

华西都市报讯(记者杨雪)9月5日23时05分,中国大熊猫保护研究中心大熊猫“水秀”在卧龙核桃坪野化培训基地半野化环境下,成功产下单胎大熊猫幼仔。至此,参加“第七梯队”的野化培训大熊猫母兽共繁育幼仔3胎4仔,2016野化培训大熊猫产仔季圆满结束。

4月初,“水秀”与大熊猫“香格”完成自然交配。经过155天的孕期,9月5日,“水秀”出现产前行为,深夜23点05分,“水秀”在无任何遮挡并持续降雨的环境下顺利产下这只幼仔。幼仔精神活力良好,叫声洪亮。目前母子各项体征均正常,幼仔性别、体重须等待进一步确定。

中国大熊猫保护研究中心从2010年至今开启了七个梯队的研究,相继成功放归大熊猫“淘淘”、“张想”和“华姣”,标志着大熊猫保护已从“扩繁保种”发展到“野外小种群复壮”的新阶段。
