摘　　要：选用35周龄伊莎产蛋鸡8只，分别安装慢性颈静脉血管插管，手术后经过适应期，待产蛋鸡体况良好、摄食正常，开始实验。实验采用自身对照法，对照期饲喂基础日粮，实验期在喂料前通过颈静脉血管插管注射大豆黄酮。应用摄食行为计算机监测系统（FIDAS系统）记录各个实验期产蛋鸡喂料后4h内的采食行为数据。结果显示，实验期（注射大豆黄酮后）与对照期相比较，产蛋鸡午前（8：00～12：00）与午后（13：00～17：00）4h内摄食量分别增加21．9％与33.9％（P〈0．05）；摄食时间分别增加3，3％与12，3％；摄食餐数分别增加14．3％与49．1％（P〈0．01）：血糖水平分别降低10．3％（P〈0.05）与21，5％（P〈0.01），瘦素水平分别升高14.9％与4．32％，胰岛素水平分别升高14．6％与27．7％（P〈0．01）。提示大豆黄酮能够促进蛋鸡摄食，并影响有关内分泌激素的水平。8 thirty-five-week-old laying hens were implanted with chronic jugular vein canula, which was used to investigate the effect of intravenous administration of daidzein on feed-intaking and plasma parameters. Compared with the control period,the feedintake from 8：00- 12：00 and 13：00- 17：00 was increased to 21.9% and 33.9 % （P 〈 0.05）,the time of feed-intaking was increased by 3.27% and 12.3% ,the meals in 4h was increased by 14.3 % and 49.1% （ P 〈 0.01 ） respectively; the plasma glucose level was reduced by 10.3 % （ P 〈 0.05） and 21.5 % （ P 〈 0.01 ）, the blood concentration of insulin was elevated by 14.6 % and 27.7 % （ P 〈 0.05）, the leptin level was also increased, but had no significantly difference compared with the control period.Throngh the experiment it was suggested that the daidzein could improve the feed-intaking of laying hen and affect endocrine hormone levels involved.
