Abstract:In order to study the differences of egg quality and flavor between different breeds of chickens，the eggs of Dagu chicken，Xianju chicken，Hy-Line Brown and Hybrid were randomly selected as experimental materials.More than ten indicators were tested including weight，quality and flavor.The results showed that egg weight of Xianju chicken was extremely significant lower than the other（P<0.01）.The egg shape index of Dagu chicken was significantly higher than those of Xianju chicken and Hy-Line Brown（P<0.05）.The differences in eggshell thickness and strength between Dagu chicken and Xianju chicken were not significant（P>0.05），but both significantly higher than that of Hy-Line Brown （P<0.05）.The protein height and Hough unit of Dagu chicken and its hybrid were significantly higher than those of the other（P<0.01）.The egg yolk ratio of Hy-Line Brown was significantly lower than that of the other （P<0.05）.Excepted Hy-Line Brown eggs，the egg shells of the other varieties were brighter，near green and blue.The egg flavoring substance of Dagu chicken and Xianju chicken were rich and smelled strong while the Hybrid and Hy-Line Brown chicken eggs had the tendency of simple flavor mainly contained with hydrogen sulfide and organic aromatic sulfide.Considering the results above，the egg quality and flavor of local breed chickens were better than introduced varieties.
