摘　　要：采用单因素随机分组试验设计,将15头泌乳中期荷斯坦奶牛随机分为3组,每组5头,进行为期60 d的饲养试验。每组奶牛分别饲喂不同日粮:Ⅰ组(基础日粮)、Ⅱ组(基础日粮+200 mg大豆黄酮/d)、Ⅲ组(基础日粮+200mg染料木素/d),试验期60 d内每隔15 d晨饲前空腹采集血样,进行血液生化及流变学指标分析。结果显示,大豆黄酮组(Ⅱ组)球蛋白(GLOB)含量显著高于Ⅰ组(P<0.05);Ⅱ组和Ⅲ组总胆固醇(TC)、甘油三酯(TG)含量分别较Ⅰ组显著降低(P<0.05);Ⅲ组高密度脂蛋白(HDL)显著高于Ⅰ组(P<0.05),但与Ⅱ组差异不显著(P>0.05);Ⅲ组同Ⅰ组相比显著降低了低密度脂蛋白(LDL)的含量(P<0.05);血清钙含量Ⅱ组和Ⅲ组分别较Ⅰ组显著提高(P<0.05),其他各项血常规指标组间差异不显著(P>0.05);奶牛血液流变学方面,大豆黄酮和染料木素的添加在一定程度上有显著降低奶牛全血粘度(ηb)及相应全血还原比粘度(ηr)、血浆粘度的作用(P<0.05);各组红细胞压积(PCV)、红细胞聚集指数(AI)差异不显著(P>0.05);红细胞刚性指数(IR)Ⅱ组和Ⅲ组均显著低于Ⅰ组(P<0.05);纤维蛋白原(FG)含量组间差异不显著(P>0.05)。Fifteen holstein cows in milk mataphase were randomly divided into three groups, which included 200 mg daidzein/d group, 200 mg genistein/d group and control for 60 d to determine the effects of daidzein and genistein on blood biochemica and hemorheological parameters. Results showed that GLOB level of genstin significantly improved than control. TC,TG,LDL level of genistein and daidzein were lower than control group（P〈0.05） ,but HDL and Ca level were highter than control（P〈0.05）. The other biochemical parameters were not significantly different （P〉0.05）. On the aspect of hemorheological parameters, ηb, ηr and IR of genistein and daidzein were lower than control group（P〈0.05）, but PCV, AI, FG were not significantly different in groups （P〉0.05）.
