SEM = standard error of the mean; GH = growth hormone; IGF-1 = insulin-like growth factors-1; CCK = cholecystokinin.

^{a, b} Different letters within a row indicate significant differences at P < 0.05.

Control, a normal protein containing 20% CP; LL, a low ratio of Lys to CP diet containing 17% CP; SL, a standard ratio of Lys to CP diet containing 17% CP; number of observation is 8.
