| 摘 要： | 本文研究樱桃谷鸭蛋形指数对孵化效果的影响，试验说明当蛋形指数为６９￣７５％时，其孵化效果最好，孵化率达８８．３％，健雏率最高，其中７１￣７３％的蛋形指数，受精蛋孵化率达９３．８％，当蛋形指数小于６９．０％时，孵化率为８１．３％，健雏率仅为８３％，大于７５％，孵化率为７９．３％，健雏率７７．３％，另外，蛋形指数对蛋精率影响不显著均为９５％。

| Abstract: | This paper studied the relation between aeg-shape of cherry Valley duck and hatchability. The test indicated thai the standard egg shape is oval.when the egg-shape index in 69-75%,the hatchability can reach 88. 3 %. The optimum egg-shape index is in the middle of 71-73%. The results showed that the effects of the egg-shape index on the fertility rate is not famous .every group is about 95%. So the eggshape index is very important during electing the eggs. |
