摘要: [目的] 旨在探索引进绿壳蛋鸡群体生产性能。[方法] 将1200只绿壳蛋鸡饲养至261日龄,统计开产日龄、开产体重、开产蛋重、261日龄体重、蛋重、绿壳蛋率、个体总产蛋量、周产蛋率等生产指标。[结果] 该群体的开产日龄为148日龄;开产体重为1328.7g;开产蛋重为35.9g;261日龄体重为1490.2g;蛋重为35.9g,产蛋量为35.98枚,单只鸡最大产蛋量为84枚;绿壳蛋率为90.39%;总产蛋量在40~49枚的个体最多;周产蛋率在前期一直保持稳定上升,27周龄以后呈现出不规律的起伏,主要范围在30.82%~50.23%,30周龄达到产蛋高峰。[结论] 该群体个体间产蛋性能存在较大差异,可以通过加强选择强度,达到提高群体产蛋性能的目的。

Abstract: [Objective] The purpose of the experiment is to study the production performance of the green eggshell layers. [Method] In this study, 1 200 green eggshell layers were adopted. We recorded the following laying traits, the age at first egg, the body weight at first egg, the first egg weight, body and egg weight at 261 days old, rate of green egg, the total egg number for 261 days, and rate of weekly laying. [Results] Results indicated that the mean age of laying the fist egg was 148 d and the body weight and egg weight were 1 338.3 g and 35.8 g, respectively. The weights of body and egg at 261 d were 1 490.2 g and 35.9 g, respectively. The total egg number for 261 d was 35.98 and the highest one is 84. The rate of green egg was 90.39%. The greatest weekly laying rate is 64.99%;the total egg number was in the range of 40 to 49 for the most individuals. The weekly laying rate steady increased in the first several laying weeks. After 27 week, the laying rate curve fluctuated sharply, which mainly ranged from 30.82% to 50.23%. Laying rates reached to the egg laying peak at 30 week. [Conclusion] The laying rates vary largely among the individuals of this group. And this can be improved with the increase of selection intensity.
