Abstract:Apparent qualities and internal qualities of four kinds of eggs were detected in this study.The results showed that the apparent qualities of four kinds of eggs had significant difference in egg weight,eggshell proportion and egg albumen proportion.In which,the egg weight of Black chicken was significantly higher than that of Dagu chicken and Anak chicken(P<0.01),and the protein weight of Black chicken was significantly higher than that of Dagu chicken(P<0.01) and Anak chicken(P<0.05).Eggshell proportion of Dagu chicken was significantly higher than that of Black chicken and Luhua chicken.To internal qualities indexes,there was no difference on eggshell thickness and yolk color,but egg shape index of Dagu chicken was significant higher than that of Luhua chicken and Anka chicken(P<0.05).Egg shell color of Black chicken was the darkest,and significantly higher than Luhua chicken(P<0.05).Egg shell strength of Luhua chicken was significantly lower than that of Dagu chicken and Anka chicken(P<0.01),albumen height(P<0.01) and Haugh Unit(P<0.05) were significantly higher than that of Dagu chicken.These results had provided a reference to breeding and improvement of Luhua chicken egg quality.
