  1. BW0, BW2, BW4, BW6, BW8, BW10, and BW12 denote body weight at 0 days, 2 weeks, 4 weeks, 6 weeks, 8 weeks, 10 weeks and 12 weeks, respectively. BW Body weight, SL Shank length, CW Chest width, SG Shank circumference, BBL Breastbone length, BSL Body slanting length. The same letters within a row indicate no significant difference (P > 0.05); different letters indicate significant differences (P < 0.05)
