在这项研究中，我们比较了两种含有不同浓度的益生菌的日粮对益生菌从饲料转移到牛奶和对泌乳奶牛瘤胃微生物群的影响。农场实验对12头哺乳期捷克Fleckvieh x Holstein奶牛进行，分为两组，每组的平均产奶量相似。每天两次，奶牛分别饲喂基于玉米青贮饲料，草地干草和补充混合物的饮食。对照组（CTRL）饲喂基础日粮，试验组（EXP）饲喂基础日粮中添加40%大豆蛋白提取物。EXP组的平均日摄入量（16 g/天）是对照组（8.4 g/天，P
In this study, we compared the effects of two diets containing different isoflavone concentrations on the isoflavone transfer from feed into milk and on the rumen microbiota in lactating dairy cows. The on-farm experiment was conducted on twelve lactating Czech Fleckvieh x Holstein cows divided into two groups, each with similar mean milk yield. Twice daily, cows were individually fed a diet based on maize silage, meadow hay and supplemental mixture. Control group (CTRL) received the basal diet while the experimental group (EXP) received the basal diet supplemented with 40% soybean isoflavone extract. The average daily isoflavone intake in the EXP group (16 g/day) was twice as high as that in the CTRL group (8.4 g/day, P
