  1. a–bMeans within a row with no common superscripts differ significantly (P < 0.05). 1NC, non-injected control group; 2SC, saline (0.85% NaCl)-injected control group. 3HW, hatching weight; 4BW, body weight. Data are the mean of 8 replicates. Orthogonal polynomial contrasts were used to determine the linear and quadratic effects of increasing concentrations of L-arginine solution
