Means with different superscripts in the same row within each linkage disequilibrium block indicate statistical difference with p<0.05.

SFA = Saturated fatty acid, MUFA = Mono unsaturated fatty acid, M/S = Mono unsaturated fatty acid/Saturated fatty acid, I_C14 = (C14:1/(C14:0+C14:1))×100, I_C16= (C16:1/(C16:0+C16:1))×100, I_C18 = (C18:1/(C18:0+C18:1))×100, CW = Carcass weight, BFT = Backfat thickness, MS = Marbling score from 1 to 9 indicating that a larger score means more abundant intramuscular fat.
