Yield index: (11.06398 – [1.25149 × Backfat thickness (mm)] + [0.28293 × Ribeye area (cm²) + [0.54768 × Carcass cold weight (kg)]) ÷ (Carcass cold weight (kg) × 100).
Marbling score: 1-trace, 9-very abundant.
Means within the same row with different superscript are statistically different (p < 0.05).
