Selection for abdominal fat pad size in mature hens has yielded two divergent strains of lean and obese chickens. The females in the obese line have been shown to have a greater amount of total body lipid by six weeks of age. Liver slices from 6- and 17-week old obese chickens incorporated significantly more 3H2O into extracted fractions of total lipid and saponified fatty acids. Palmitate esterification by abdominal fat pad slices from 12-week old pullets was the same for both strains when activity was expressed per unit weight of tissue. The twofold difference in size between the lean and obese fat pads at this age, however, indicates a significantly greater degree of total esterification in the obese birds. At 6-, 12-, and 17-weeks of age, the two lines exhibited similar concentrations of plasma glucose, total protein, and triglycerides.
对成年母鸡腹部脂肪垫大小进行选育，已培育出两种截然不同的品系：瘦鸡和肥胖鸡。肥胖品系的雌性鸡在6周龄时，全身脂质总量更多。6周龄和17周龄肥胖鸡的肝脏切片在总脂质和皂化脂肪酸的提取物中掺入的3H2O显著更多。当以每单位组织重量表示活性时，12周龄小母鸡腹部脂肪垫切片的棕榈酸酯化在两个品系中相同。然而，这个年龄瘦鸡和肥胖鸡脂肪垫大小的两倍差异表明，肥胖鸡的总酯化程度显著更高。在6周龄、12周龄和17周龄时，两个品系的血浆葡萄糖、总蛋白和甘油三酯浓度相似。
