Thermal manipulations during broiler embryogenesis and the post-hatch period can improve thermotolerance acquisition, alleviate the heat stress response, reduce production loss and death in broiler challenged by heat stress.

• 在胚胎发育后期和育雏早期分别给予鸡胚或雏鸡适当强度的高温刺激,可以激活或完善其在极端热环境下的体热调控机制,增强其生长后期再次遭遇极端热环境的适应能力,从而从根本上减轻肉鸡遭遇夏季高温而引起的热应激反应,减缓生长速度的下降,减少死亡,大幅度降低夏季高温对肉鸡生产造成的损失。
