Abstract：The objective of this study was to find the most practical nutrition program for producing high-quality beef by analyzing the effect of growth-period nutrition on the slaughter performance and beef carcass grade. Thirty castrated 7-month-old Wannan cattle of similar body weights were randomly and equally divided into five groups: G1.9, G1.6, G1.3, G1.0 and G0.7 that were respectively provided with a feed concentrate at 1.9%, 1.6%, 1.3%, 1.0% and 0.7% of their body weight for twenty-four months, the fattening-period was three months and the feeding program was same. The results showed that the growth-period nutritional level and feeding program of group G1.0 was most conducive to fat deposition and distribution in the ribeye, increasing the proportions of high quality beef in beef carcasses and pure meat and making the beef carcasses reaching the choice beef grade.
