A flock of commercial Single Comb White Leghorn laying hens, diagnosed as having fatty Liver Hemorrhagic Syndrome (FLHS), was surveyed to ascertain the relationship between comb color and selected FLHS characteristics. Twenty-eight hens with and without pale combs were selected from 14 cages for paired comparisons. Hens with pale combs had a higher (P less than or equal to .05) liver score and relative liver weight than hens with normal combs. Differences were not detected in BW, comb weight, relative comb weight, liver fat and plasma estrogen concentration. In flocks diagnosed with FLHS, comb appearance is associated with a higher incidence of FLHS.
对一群被诊断患有脂肪肝出血综合征（FLHS）的商用单冠白来航蛋鸡进行了调查，以确定鸡冠颜色与选定的FLHS特征之间的关系。从14个笼子中挑选出28只鸡冠颜色有无变浅的母鸡进行配对比较。鸡冠颜色变浅的母鸡比鸡冠正常的母鸡肝脏评分和相对肝脏重量更高（P≤0.05）。在体重、鸡冠重量、相对鸡冠重量、肝脏脂肪和血浆雌激素浓度方面未检测到差异。在被诊断患有FLHS的鸡群中，鸡冠外观与FLHS的较高发病率相关。
