Two experiments were conducted to elucidate the genetic variation in the liver lipid content of coturnix quail. In Experiment 1, the change of the liver lipid content with advancing age was studied. In Experiment 2, the genetic variation of the liver lipid content at 4 weeks of age was analyzed. Liver lipid was extracted with ethanol-ether solution and weighed. Genetic parameters of liver lipid content, body weight, and liver weight were estimated from sib analysis. The means of liver lipid content at 2 and 4 weeks of age were approximately 25% on a dry weight basis in both sexes. After 6 weeks of age, the liver lipid content of the female was higher than that of the male. The liver lipid content of the egg-laying female was slightly higher than that of the nonlaying female. Heritability (h2sire) of liver lipid content from 4-week-old coturnix quail was estimated as h2sire: .62 +/- .73.
进行了两项实验以阐明鹌鹑肝脏脂质含量的遗传变异。在实验1中，研究了肝脏脂质含量随年龄增长的变化。在实验2中，分析了4周龄时肝脏脂质含量的遗传变异。用乙醇 - 乙醚溶液提取肝脏脂质并称重。通过同胞分析估计肝脏脂质含量、体重和肝脏重量的遗传参数。在2周龄和4周龄时，两性肝脏脂质含量的干重平均值约为25%。6周龄后，雌性的肝脏脂质含量高于雄性。产蛋雌性的肝脏脂质含量略高于不产蛋雌性。4周龄鹌鹑肝脏脂质含量的遗传力（父系遗传力，h2sire）估计为h2sire: 0.62±0.73 。
