Abstract In this paper, carcass quality indicators for carcass grading of yellow cattle from south China were screened and analyzed by factor analysis and correlation analysis. Cluster analysis was carried out on the selected parameters including beef marbling, body type and loin eye muscle area. These analyses confirmed beef marbling (fat content) to be the quality indicator for carcass grading. The grading standards based on beef marbling were established as follows: grade 1, 1.32% ≤ marbling ＜ 7.36%; grade 2, 7.36% ≤ marbling ＜ 17.86%; grade 3, 17.86% ≤ marbling ＜ 22.43%; and grade 4, marbling ≥ 22.43%.
