摘要
对宁夏地区目前普遍饲养的七个品种560只商品蛋鸡血清酯酶—1（ES-1）、转铁蛋白（Tf）、白蛋白（Alb）和前白蛋白（Pa）多态性进行了遗传检测。结果表明：七个品种的商品蛋鸡血清ES-1、Tf、A1b、Pa诸位点均显示多态性，各鸡种的基因频率存在一定的差异，据基因频率计算出群体问标准遗传距离，海兰与北京红鸡的遗传距离最小（0．0075），亲缘关系最近；狄卡与亚发次之（0．0132）；芦花鸡与海兰的遗传距离最大（0．1167）并与其它品种间的遗传距离都较大，说明芦花鸡与其它鸡种亲缘关系最远，其余距中．聚类分析结果为在不同蛋鸡种中预测杂种优势提供理论依据，达到较准确、直接、省时确定出较高杂种优势的亲本。
Adopting vertical polyacrylamide gel and polyacrylamide concentration gradientgel electrophoresis, the serum esterase-1 (Es-1) isozymes and transfering (Tf), albumin (A1b),prealbumin (Pa) protein polymorphism of 560 commodity laying hens, seven breeds in Ningxiawere analyzed. The results of analysis showed that Es-1,Tf, Alb, Pa of seven greeds exibited ahigher polymorphism and gene frequency had some ditTerence. Heredity distance amongcolonies was counted according to the gene frequency. The results showed that the hereditydistance between Hai Lan and Peking red chickens was the shortest (0.0075), the hereditydistance between Dika and Yafa sholter(0.0132) than others, the heredity distance between Luhuaand Hailian the heighest (0.1167) of all. Others' were medium quality. Adopting the way offtlzzy mathematics, the shortest distance, the poly class of seven breeds commodity laying henhad been analysed.
