Effect of constant light exposure on growth performance and serum hormone concentration. A Body weight (1 d, 7 d, n = 39 (LD), n = 40 (LL); 14 d, 21 d, n = 20); B Average daily feed intake (1st week, n = 2; 2nd and 3rd week, n = 4); (C) Feed conversion ratio (1st week, n = 2; 2nd and 3rd week, n = 4); D Serum corticosterone content (n = 10); E Serum melatonin content (n = 10); F Serum 5-HT content (n = 10). Values are mean ± SEM, *P < 0.05, **P < 0.01, compared with LD
