摘　　要：选取55周龄伊莎产蛋鸡24羽,随机分为3组。Ⅰ组饲喂基础日粮(对照组),Ⅱ、Ⅲ组分别饲喂日粮+大豆黄酮(Daidzein,Da)3mg/kg和15mg/kg。结果显示:产蛋后期母鸡的血清瘦素水平对照组平均为(1.37±0.27)ng/ml,而添喂Da组均降低;添喂Da组血清17β-雌二醇水平和尿酸含量均显著减少;而血清甲状腺激素浓度变化不显著。本研究结果显示,添喂大豆黄酮后,可改变产蛋鸡有关内源激素和代谢物水平。Twenty four laying hens were randomly allocated into 3 groups:basal diet,basal diet+3mg/kg daidzein,basal diet+15mg/kg daidzein.The result indicated that the serum concentration of leptin of layers was(1.37±0.27)ng/ml;Compare with control group,serum leptin and 17β-estradiol levels were significantly reduced,whereas triiodothronine and thyroxin concentrations were not altered.Serum uric acid level was greatly reduced.
