摘　　要：本试验采用了 3个生产阶段的蛋用鹌鹑。 35日龄开产期蛋用鹌鹑日粮中添加 3mg/kg大豆黄酮 ,鹌鹑的产蛋率和血液中T3 水平均发生显著性提高 (P <0 0 5 )。 7月龄蛋用鹌鹑日粮中添加 3mg/kg大豆黄酮 ,可显著提高鹌鹑的产蛋率 (P <0 0 5 )和血液中T3 水平 (P <0 0 5 ) ;而日粮中添加 6mg/kg大豆黄酮则使鹌鹑的产蛋率显著下降 (P <0 0 5 )。 12月龄蛋用鹌鹑日粮中添加 6mg/kg大豆黄酮 ,鹌鹑的产蛋率提高 10 3% (P <0 0 1) ;血液中T3 、T4和IGF 1水平分别提高 34 8% (P <0 0 1)、2 7 6 % (P <0 0 5 )和 30 8% (P <0 0 5 )。本次研究结果表明 ,日粮中添加一定剂量大豆黄酮能显著增加开产期、高峰期和后期蛋用鹌鹑的产蛋率 。Three different laying stage quails have been studied in this research.Supplementation of daidzein(Da,at the dose of 3 mg/kg) greatly increased the laying rate and serum T 3 level of 35 day old quails by 6 9%(P<0 05) and 22 8% (P<0 05),respectively.Laying qualils(7 months of age) fed diet containing 3 mg/kg of Da showed obviously higher laying rate (P<0 05) and T 3 level (P<0 05),while those treated with Da at the dose of 6 mg/kg showed a decrease of laying rate(P<0 05).Moreover,the laying rate of quails(12 months of age) fed diet containing 6 mg/kg of Da was apparently increased(P<0 01).Serum T 3,T 4 and IGF 1 elevated by 34 8%(P<0 01),27 6%(P<0 05) and 30 8%(P<0 05),respectively.These results indicate that optimum concentration of Da can significantly promote laying rate of different laying stage quails.
