The effect of thermal manipulation (TM) during embryogenesis on body weight in post-hatch broiler chicks from day 1 to day 35 (n = 20). Control = 37.8°C for 24 h; TM1 = Thermal manipulation at 38.5°C for 18 h; TM2 = Thermal manipulation at 39°C for 18 h; TM3 = Thermal manipulation at 39.5°Cfor 18 h, TM4 = Thermal manipulation at 40°C for 18 h. a–b Within the same day, means ± SD with different superscripts differ significantly (P < 0.05)
