Abstract: 【Objective】 The purpose of this experiment was to compare and evaluate the egg quality and nutritional value of eggs from four local chicken breeds in Southern China. 【Method】 Chongren partridge chicken,Wumeng crested chicken,Yao chicken,Danzhou chicken and Hy-line Brown laying (control) were taken as the research objects,and 50 chickens of each breed were selected.Under the same feeding conditions,90 eggs were randomly selected for each breed.The egg quality and the contents of nutrients such as crude fat,crude protein,trace elements,amino acids and fatty acids in the eggs were compared and analyzed. 【Result】 The egg weight of Hy-line Brown laying was significantly higher than that of local breeds (P<0.05),while the egg weight of Chongren partridge chicken and Danzhou chicken were significantly lower than those of other breeds (P<0.05).The egg yolks of Chongren partridge chicken and Wumeng crested chicken were darker in color,which was significantly different from those of Danzhou chicken and Hy-line Brown laying (P<0.05).The eggshell strength of Danzhou chicken was significantly lower than that of Chongren partridge chicken,Wumeng crested chicken and Hy-line Brown laying (P<0.05).In terms of nutritional components,the cholesterol content in Chongren partridge chicken eggs was significantly lower than that in other breeds (P<0.05).The calcium content in the eggs of Danzhou chicken was significantly higher than that of Yao chicken and Hy-line Brown laying (P<0.05),and the iron content was significantly higher than that of other breeds (P<0.05).The phosphorus content in the eggs of Hy-line Brown laying was significantly higher than that of other breeds (P<0.05).In addition,the vitamin E content in the eggs of Wumeng crested chicken and Danzhou chicken was significantly higher than that of other breeds (P<0.05).The content of glutamic acid in the eggs of Wumeng crested chicken was significantly higher than that of other breeds (P<0.05),and the content of polyunsaturated fatty acids was significantly higher than that of Chongren partridge chicken,Danzhou chicken and Hy-line Brown laying (P<0.05). 【Conclusion】 The local chicken breeds in Southern China generally performed well in terms of nutritional value and flavor,especially in terms of cholesterol and branched-chain amino acid composition.These results had important reference value for the further development and utilization of local chicken breeds.
