摘　　要：采用聚丙烯酰胺凝胶电泳技术测定了秦川牛(148头)血红蛋白(Hb)、运铁蛋白(Tf)、后运铁蛋白(PTf)、血清白蛋白(Alb)和后白蛋白(Pa)的遗传多样性。分析了各多态座位不同基因型与秦川牛若干繁殖性状的关系。结果表明:Hb AA型母牛的初情期年龄(AFS),初产年龄(AFC)极显著早于Hb AB型母牛(P<0.01)。Tf AA型母牛的初情期和初产年龄显著早于Tf DD型母牛(P<0.05)。PTfSS型母牛的初情期显著早于PTfFS型母牛和PTfFF型母牛(P<0.05)。Alb AA型母牛的初情期显著早于Alb AC型母牛(P<0.05)。Tf A基因对D基因的替代平均效应值初情期提前1.68 d,初产年龄提前19.89 d。AlbA基因对B基因的替代平均效应值初情期提前8.06 d。Haemoglobin（Hb）, transferring（Tf）, post transferring（PTf）, albumin（Alb）, post albumin（Pa） polymorphism in the blood of 148 individuals in Qinchuan Yellow Cattle were investigated by polyacrylamide gel electrophoresis in this study. Data on their genotype and gene frequencies of the five polymorphic loci were tabulated. Relationships between genetic markers and reproductive performance were analyzed by least square. The results revealed that AFS and AFC of Hb AA were remarkable earlier than Hb AB＇s（P〈0.01）. AFS and AFC of Tf AA were remarkable earlier than Tf DD＇s（P〈0.05）. AFS of PTf SS was remarkable earlier than PTf FS＇s and PTf FF＇S（P〈0.05）. AFS of Alb AA was remarkable earlier than Alb AC＇s（P〈0.05）. CI of Pa AA was remarkable shorter than PaBB＇s. The gene replacement average effect of Tf A substitute TfD was AFS 1, 68 days and AFC 19.89 days. The gene replacement average effect of Alb A substitute Alb B was AFS 8.06 days.
