In the non-laying pullet and the cockerel it was observed that there was no significant variation in the activities of ATP citrate lyase and ;malic' enzyme whereas in the laying hen there was a significantly greater activity of both these enzymes. Parallel increases in liver lipid content in the laying hen were also observed. Three glycolytic enzymes, phosphofructokinase, fructose diphosphate aldolase and pyruvate kinase, did not exhibit any significant variation in enzyme activity with the onset of egg laying. These results are discussed in relation to the hormonal status of the birds and also the demands of egg production for lipid.
在非产蛋小母鸡和小公鸡中，观察到ATP柠檬酸裂解酶和苹果酸酶的活性没有显著变化，而在产蛋母鸡中，这两种酶的活性显著更高。同时还观察到产蛋母鸡肝脏脂质含量也相应增加。三种糖酵解酶，即磷酸果糖激酶、果糖二磷酸醛缩酶和丙酮酸激酶，在开始产蛋时酶活性没有表现出任何显著变化。结合鸟类的激素状态以及产蛋对脂质的需求对这些结果进行了讨论。
