摘　　要：为探索草原红牛血液蛋白多态性与生产性能的相关关系,采用聚丙烯酰胺凝胶电泳法检测了13头草原红牛和18头利×草杂交牛的血红蛋白(Hb)、白蛋白(Alb)和后白蛋白(Pa)3个血液蛋白多态性位点,结果发现Hb、Alb、Pa分别受2个等位基因控制,其中Hb在草原红牛中发现1头牛有4条带的变异;血液蛋白多态性位点与生产性能的方差分析表明,3个蛋白位点对草原红牛及其利木赞改良牛群体的某些性状存在正相关或负相关。In order to investigate the correlations between the blood protein polymorphic points and performance of Red Steppe, the polyacrylamide gel electrophoresis （ PAGE ）were employed to detect hemoglobin （Hb）, albumin （Alb）,postalbumin（Pa）-three blood protein polymorphic points of 13 Red Steppe and 18 limousin × Red Steppe. The results showed that Hb,Alb and Pa cotroled by 2 allelomorpb respectively;the 4 bands of Hb had dissociation in 1 Red Steppe. The of variance analysis of the blood protein polymorphic points and performance suggested 3 protein points had positive or negative effects on some traits of Red Steppe and limousine.
