摘　　要：选取55周龄伊莎产蛋鸡24羽,随机分为3组对照组饲喂基础日粮,实验、组分别饲喂基础日粮+Da3mg/kg和Da15mg/kg。结果显示与对照组相比较,、组产蛋率和只日蛋重均显增加,料蛋比均显著下降。产蛋后期的血清瘦素水平对照组平均为1.37±0.27ng/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,可通过改变产蛋鸡有关内源激素和代谢物水平,同时改善该蛋鸡的生产性能。提示大豆黄酮可通过内分泌途径调控其产蛋。24 fifty-five-week-old laying hens were randomized into 3 groups:basal diet,basal diet+3mg/kg daidzein,basal diet +15mg/kg daidzein. Compared to control,the egg laying performance of both basal diet +daidzein groups was improved apparently;Serum leptin and 17β-estradiol levels were significantly reduced in experimental group Ⅱ,Whereas triiodothronine and thyroxin concentration were not altered.Serum uric acid level was greatly reduced.
