摘要
本研究通过对江西绿壳蛋鸡F1代产蛋性能、孵化效果和蛋品质进行分析,为江西绿壳蛋鸡选育提供参考。试验选取300日龄江西绿壳蛋鸡306只及其鸡蛋80枚,分别测定、分析蛋鸡产蛋性能及种蛋孵化效果和蛋品质,并对这些指标进行相关性分析。经测定,试验蛋鸡平均体重为1 596.99 g,平均蛋重为50.57 g,平均产蛋数为14.53枚;群体平均受精率为93.69%,平均死精率为5.55%,平均健雏率为84.3%,平死胚率为13.9%。群体平均蛋形指数为1.28,平均哈氏单位为71.77,平均蛋壳强度为4.44 kg/cm2。相关分析显示,健雏率与蛋重、蛋壳颜色与蛋形指数间呈显著相关(P<0.05);健雏率与死胚率、蛋壳强度与蛋壳厚度间呈极显著相关(P<0.01)。以上结果表明,江西绿壳蛋鸡F1代蛋品质优良,产蛋性能、孵化效果较好,但仍需进一步选育。
The purpose of this study was to provide the reference to Jiangxi Green-eggshell breeding through the analysis of laying performance,hatchability and egg quality in the first generation of Jiangxi Green-eggshell layers at 300-days old. 306 Jiangxi Green-eggshell layers and 80 eggs were selected to determine the laying performance,hatchability and egg quality among families,and the correlation between the hatchability and egg quality were analyzed also. The results were as fellows： The average body weight of these hens was 1 596.99 g,the average egg weight was 50.57 g,the average egg-laying number was14.53,the average fertility rate was 93.69%,the average dead fertile egg rate was 5.55%,the average healthy chick rate was 84. 3%,the average dead embryo egg rate was 13. 9%,the average egg shape index was 1.28,the average Haugh unit was 71.77,and the average eggshell strength was 4.44 kg/cm2.The healthy chick rate and the egg weight had significant correlation,as well as the eggshell color and the egg shape index（P〈0.05）. The healthy chick rate had extremely significantly correlation with the dead fertile egg rate（ P〈0. 01）,as well as the eggshell strength and the eggshell thickness（ P〈0. 01）. General-ly,the first generation of Jiangxi Green-eggshell layers had good egg quality,higher laying performance and hatchability,but they still need to be further selected.
