Late prenatal chicken embryos in eggs injected with saline showed a feeble homeothermic metabolic response to gradual cooling. This response was absent in thiourea-treated eggs. This suggests that the incipient homeothermic metabolic response before paranatal life may be attributed to thyroid development. 2. The compensatory metabolic response disappeared in embryos exposed to a hypoxic environment, while it was augmented in eggs in pure O2, decreasing as ambient temperature fell. 3. These results may indicate that the homeothermic metabolic response in late embryos is O2-conductance-limited and power-limited as previously suggested.

向鸡蛋中注射生理盐水的晚期产前鸡胚胎对逐渐冷却表现出微弱的恒温代谢反应。在经硫脲处理的鸡蛋中这种反应不存在。这表明产前生命之前初期的恒温代谢反应可能归因于甲状腺发育。2. 暴露于低氧环境的胚胎中代偿性代谢反应消失，而在纯氧环境中的鸡蛋中该反应增强，并随环境温度下降而减弱。3. 这些结果可能表明，如之前所提出的，晚期胚胎中的恒温代谢反应受氧传导限制和功率限制。
