Chicken eggs incubated under hatchery conditions for 19 days show significant decreases in the total content of water and organic nitrogen, but not of sodium or potassium. The hypothesis is discussed that the formation of gaseous nitrogen is responsible for the nitrogen loss.
在孵化场条件下孵化19天的鸡蛋，其水分和有机氮的总含量显著下降，但钠或钾的含量没有下降。本文讨论了气态氮的形成是导致氮损失的原因这一假说。
