| 摘 要： | 为研究大豆黄酮对奶牛日产奶量、乳脂率及乳蛋白含量的影响，选用24头中国荷斯坦奶牛，按产奶量、泌乳月及胎次配对随机分成3组（n=8），试验组在日粮中分别添加30mg／kg（DA1）和60mg／kg（DA2）的大豆黄酮。于第1，10，20天，测定产奶量、乳脂率及乳蛋白含量。结果表明：与对照组相比较，最终试验组平均Et奶产量分别提高7．62％（DA1，P〈0．05）和15．18％（DA2，P〈0．01）。乳脂率3组间没有明显差异，而乳蛋白含量DA2组比对照组增加20．07％，差异显著（P〈0．05）。

| Abstract: | In order to determine the effect of daidzein supplementation in diet of lactating cows on milk yield,Holstein lactating cows were selected and randomly grouped by milk yield,lactation period and parity.Three treatments were daidzein supplementation levels of 30mg/kg(DA1),60mg/kg(DA2) and control,respectively.The daily milk yield and percentages of milk fat and protein were investigated in day 1,10 and 20 of the trial.The results showed that compared with control,daily milk yield increased 7.62%(P<0.05) and... |
