Abstract：Abstract：This study was conducted to quickly predict the weight and percent of retail cuts on the cattle slaughtering line, to grade Kerchin cattle according to their carcass quality and to realize the policy of selling good quality cattle at a high price. 60 Kerchin cattle were slaughtered, chilled and cut. Cattle quality were measured as prediction of weight and percent of retail cuts. The predictors were used to construct by correlation analysis and multiple linear regression based on the SPSS 16.0. The equations for prediction of weight and percent of retail cuts were Y1=- -7.357 + 1.122?á HCW － 0.155 ?á LW + 0.077 ?á REA (R2 = 0.986，RMSE = 2.842) and Y2= 42.971 + 0.182 ?á HCW－ 0.098 ?á LW + 0.021 ?á REA (R2= 0.930，RMSE = 0.516), respectively. The equations obtained could be used for prediction of weight and percent of retail cuts of Kerchin cattle.
