Abstract:

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 was 14.53, 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). Generally, 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.

Key words: Green-eggshell layers; laying performance; hatchability; egg quality; correlation
