摘要
对11枚斑嘴鸭的卵进行人工孵化及育雏试验,结果表明:雏鸟早期生长发育阶段大致可划分为3个时期,第1时期是快速生长期,第2时期是急速生长期,第3时期是缓速生长期;斑嘴鸭的体重、翅长、跗蹠、体长、尾长、嘴长变化与日龄相关显著。
The experiment on artificial incubation and brooding of 11 Anas poecilorhyncha eggs showed that: the early growth period of nestling can be divided into three stages,the first was fast growing stage,the second was the stage of increasing intensively and the last was the stage of growing slowly.Changes in Weight,wing length,tarsometatarsus,body length,tail lengt and,beak length had a notable relationship with day old.
