| Body weight (g) | 150.8±6.8a | 521.7±21.6b | 1862.5±34.3c | 4124.0±77.4d |
| Right breast muscle (g) | 6.2±0.4a | 36.9±1.9b | 185.9±3.2c | 503.5±20.1d |
| Plasma insulin (ng/ml) | 1.90±0.37 | 1.47±0.38 | 1.34±0.21 | 0.87±0.19 |
| Plasma Nτ-methylhistidine (nmol/ml) | 22.55±2.27ab | 19.08±1.96ab | 15.74±1.55a | 28.36±4.26b |
Values are means±SEM of six chickens in each group. Data were analyzed by the Tukey-Kramer method. Groups with different letters were significantly different (P<0.05).
