Haemoglobin transferring, post transferring albumin post albumin polymorphism in the blood of 151 individuals in Qinchuan Yellow Cattle were investigated by poly acrylamide gel electrophoresis in this study. Date on their phenotypes and gene frequency of the five poly morphic loci were tabulated. Relationships between genetic markers and growth performance were analyses by least square. The results revealed that 12 months’ weight and 24 months’ weight of Hb AA are remarkable heaver than Hb AB’s. 12 month’s weight, 18 months’ weight and 24 months’ weight of PTfFF are remarkable heavier than PTfFS’s .12 months’ weight and 18 months’ weight of AlbAA are remarkable heavier than Alb AB’s. 6 months’ weight of PaBB is remarkable heavier than Pa AB’s Birth weight of Hb AA/Tf DD is heaviest. 12 months’ 18 months’ and 24 months’ weight of the combination of gene type Hb AB/Tf DD are the heaviest. The gene replace average benefit of TfD substitude TfA are Birth weight 0.1754 kg, 24 months’ weight 0.6320 kg. On the basis of gene benefit and gene replace average benefit, the return equation of individual private gene into genetype was established.
