【摘要】 为了建立不同地区朱种群和加快繁殖 ,2 0 0 2年从洋县引种朱 6 0只到秦岭北麓 ,用人工孵化育雏和亲鸟自然孵化育雏相结合的方法 ,并加强幼鸟管理 ,对其中 14对繁殖朱进行了 2年观察研究。结果显示当年产卵 45枚 ,受精卵 35枚 ,受精率 77.78%,出雏 32只 ,成活2 6只 ,成活率 81.2 5%(2 6 / 32 )。 2 0 0 3年产卵 46枚 ,受精卵 40枚 ,受精率 86 .95%,出雏 35只 ,成活 34只 ,成活率 97.1%(34 / 35)。其中 ,2 0 0 2 ,2 0 0 3年亲鸟自然孵化 ,受精率分别为88.89%和 10 0 %,成活率均为 10 0 %,亲鸟自然孵化育雏优于人工孵化育雏更多还原

【Abstract】 This study aimed at establishing Crested ibis population in various regions and accelerating its reproduction. Sixty Crested ibis were introduced from Yang Country to the north foot of Qin Mountain in 2002. Combining artificial hatching and breeding with natural hatching and breeding, strengthening the management of the young birds it have observed 14 couples reproductive Crested ibis for 2 years. And the result showed:35 fertilized in 45 eggs,fertilization rate was 77.78%, 26 survived in 32 nestlings,livability was 81.25%(26/32);in 2003 year 40 fertilized in 46 eggs,fertilization was 86.95%,34 survived in 35 nestlings,livability was 97.1%(34/35). In 2002,2003, natural hatching and breeding,fertilization rate was 88.89% and 100%,livability was 100%.更多还原
