BFT1: backfat thickness at shoulder; ABT: average backfat thickness; BFT2: backfat thickness at thorax-waist; BFT3: backfat thickness at buttock; 67RIBBF: backfat thickness between 6^th and 7^th ribs; RN: rib numbers; CL1: Carcass body length 1; CL2: Carcass body length 2; LFP: Leaf fat percentage; IFR: Internal fat rate. Data were shown as means ± S.D. (standard deviation). Different superscript small letters in one row indicate significance level at P<0.05; Different superscript large letters in one row indicate significance level at P<0.01; Asterisk (*) represents significance level at P<0.05.
