Values are shown as the means ± standard error. Values with different superscripts in the same column differ significantly at P < 0.05 (a,b) and P < 0.01 (A,B) after Bonferroni correction. Body length (BL),withers height (WH), chest depth (CD), chest circumference (CC), back fat thickness (BF), ultrasound loin muscle area (ULA) and intramuscular fat content (IFC).
