  1. W1, W2, W3, W4, W5, W6, W7, and W8 represent water supply rate at 100 mL per 1d, 2d, 3d, 4d, 5d, 6d, 7d, 8d, respectively. Data are presented as means ± SE (n = 4). Different lowercase letters indicate significant differences between indices within water supply treatments (P < 0.05). The same lowercase letters indicate insignificant differences (P > 0.05).
