Changes in fatty acid composition of triacylglycerols and phospholipids of the hen liver lipid on coming into egg production were described. Of the major fatty acids of triacylglycerols, a high content of oleate and low content of stearate and polyenoic acids were observed in the hen liver at all ages (97 to 167 days of age). In contrast, high stearate and polyenoic acids were present in the liver phospholipids at all ages. The oleate content in triacylglycerols was twice that of phospholipids. Triacylglycerols of the hen liver were more unsaturated than phospholipids throughout the experiment. The triacylglycerols of the control and estrogenized male chicks were also more unsaturated than the phospholipids. The distribution patterns of carbon-18 fatty acids (stearate, oleate, and linoleate) of triacylglycerols and phospholipids in liver lipid were examined. Both females and males showed similar distribution patterns of carbon-18 fatty acids of the triacylglycerols. In the phospholipids, all birds also showed similar distribution patterns, but these patterns were distinctly different from those of the triacylglycerols.
本文描述了母鸡开始产蛋时肝脏脂质中三酰甘油和磷脂的脂肪酸组成变化。在三酰甘油的主要脂肪酸中，各年龄段（97至167日龄）的母鸡肝脏中油酸含量高，硬脂酸和多不饱和脂肪酸含量低。相比之下，各年龄段肝脏磷脂中硬脂酸和多不饱和脂肪酸含量高。三酰甘油中的油酸含量是磷脂的两倍。在整个实验过程中，母鸡肝脏的三酰甘油比磷脂更不饱和。对照和经雌激素处理的雄性雏鸡的三酰甘油也比磷脂更不饱和。研究了肝脏脂质中三酰甘油和磷脂的碳-18脂肪酸（硬脂酸、油酸和亚油酸）分布模式。雌性和雄性三酰甘油的碳-18脂肪酸分布模式相似。在磷脂中，所有鸟类的分布模式也相似，但这些模式与三酰甘油的模式明显不同。
