Abstract: This experiment was conducted to study the slaughter of the relationship between meat traits and genotypes. This study selected Red cattles as the experimental group, using PCR-SSCP method of detection of bovine IGFBP6 gene exon 2 polymorphism analysis with the slaughter of the relationship between meat traits by the GLM model of the SPSS 13.0 statistical software to analysis. The results showed that IGFBP6 gene had a polymorphic site A180G in exon 2, at the same time had three genotypes of AA, AB and BB. Between the three genetypes,AB and BB genetypes were very significant higher than AA genetype in net meat weight (P<0.01),and were significant higher than AA genetype in eye muscle area and bone weigh (P<0.05), while in the ante-mortem live weight, carcass weight, kidney fat weight and rib fat weight in the three genotypes were no significant differences (P>0.05). These results indicated that the slaughter of meat was associated with certain traits, accessibility for the future protection of breeding species of Red cattle to provide a theoretical basis, and Red cattle of beef with traits improve the delivery methods and theoretical on the guidance.
