The hypothesis that chickens of a lean rather than a fat line are hyperresponsive to dietary cholesterol was tested. Birds of the fat line showed higher initial plasma total cholesterol levels. The addition of 1% (w/w) of cholesterol to the diet significantly increased plasma cholesterol concentrations but there was no difference in response between the two lines. Dietary cholesterol increased liver cholesterol in both lines, the effect being more pronounced in birds of the lean line. It is concluded that the responsiveness of plasma cholesterol to dietary cholesterol in chickens is not related to the degree of body fatness.
对瘦肉型品系而非脂肪型品系的鸡对膳食胆固醇反应过度这一假说进行了检验。脂肪型品系的鸡初始血浆总胆固醇水平较高。在日粮中添加1%（w/w）的胆固醇可显著提高血浆胆固醇浓度，但两个品系之间的反应没有差异。日粮胆固醇使两个品系的肝脏胆固醇均增加，在瘦肉型品系的鸡中这种作用更为明显。得出的结论是，鸡血浆胆固醇对膳食胆固醇的反应性与体脂程度无关。
