摘要： 以35周龄固始鸡所产蛋为素材，研究了其5个品变种的蛋质特性，结果表明：（1）各品变种均保留了固始鸡原有的蛋壳坚厚（54.67~58.60μm），蛋黄鲜红色(8.56~9.17)，蛋黄胆固醇含量低（221.11~233.94mg/枚）等优良蛋质特征；同时也存在蛋重（48.13~50.51g）和蛋形指数（1.21~1.30）偏低的缺点；（2）蛋质各性状的相关性在不同品变种表现存在差异，如胆固醇与蛋重（黄乌和花羽鸡，r=0.79878~0.80938）（P<0.05）和蛋清粗蛋白含量（花羽鸡，r=0.88288）（P<0.01）呈强的正相关，而与蛋壳重（白乌鸡，r= -0.98537）和蛋黄粗蛋白含量（黄乌鸡，r=-0.9225）呈强的负相关（P<0.01）。

Abstract: The eggs of 35-week-age Gushi chicken were selected to investigate the egg quality traits of 5 different varieties. The results showed that：（1）The excellent egg quality traits of hardness and eggshell thickness（54.67~58.60μm）, florid yolk (8.56~9.17) and low content of yolk cholesterol （221.11~233.94mg/egg） remained in every variety; but there were some drawbacks, such as low egg weight（48.13~50.51g）and egg shape index（1.21~1.30）in some varieties. (2)The result of correlation analysis of every egg trait showed that it had difference in different varieties, such as cholesterol：between cholesterol and egg weight there was significantly positive correlation (p<0.05) (r=0.79878~0.80938)both in Yellow feather Gushi Chicken with black skin and piebald feather Gushi Chicken, and between cholesterol and content of egg white crude protein the correlation was significantly positive (p<0.01) (r=0.88288)in piebald feather Gushi Chicken; meanwhile，there was negative significantly correlation (p<0.01) between cholesterol and weight of egg shell (white feather Gushi Chicken with white skin, r= -0.98537)and cholesterol and yolk crude protein(yellow feather Gushi Chicken with black skin, r= -0.9225).
