Abstract:The experiment was to compare and analyze the egg quality and percentage of Wuhei chickens with different eggshell color.A total of 120 30-week-age Wuhei hens of similar weight and peak laying period were selected. The experiment lasted for 5 weeks (31-35 weeks, respectively). At 33 and 35 weeks, 60 powder shell eggs and 60 green shell eggs were collected to determine the egg quality index. During the experiment, the number of powder shell eggs and green shell eggs were recorded on a weekly basis, and the percentage of powder shell eggs and green shell eggs were calculated after the experiment. The results showed that: 1) At 33 weeks, there were no significant differences in egg quality indexes between powder shell eggs and green shell eggs (P > 0.05).The egg weight of powder shell eggs was higher than that of green shell eggs, and other indexes of green shell eggs were higher than that of powder shell eggs. At 35 weeks, egg type index and protein height of green shell eggs were significantly higher than that of powder shell eggs (P < 0.05), but there were no significant differences in other indexes between powder shell eggs and green shell eggs (P > 0.05). 2) During the laying of eggs from 31 to 35 week, green shell eggs were mainly produced of Wuhei chickens , accounting for more than 75% of green shell eggs, while powder shell eggs accounted for between 23.15% and 24.72%. A combination of all index, there was no significant difference in egg quality of Wuhei chickens between powder shell and green shell eggs, and the proportion of green shell eggs was larger.
