The short-term actions of Lavandula officinalis and Equisetum arvense dry extracts, and of isoquercitrin, flavonoid present in Equisetum arvense, on in vitro fermentation by rumen microbes were studied in batch culture. The orchard grass hay:barley ratios in the three experimental diets were 100:0, 75:25, 50:50 on a DM basis. The production rates of all volatile fatty acids except isobutyrate were strongly influenced by the composition of the diet and to a lesser extent, by plant extracts, with significant interactions between both factors. When hay was the only substrate, the addition of L. officinalis and E. arvense enhanced the fermentation rate by 50%, through an increased release of acetate and propionate. On the contrary, with the two other diets, the fermentation rate was strongly lowered by isoquercitrin. Gas outputs were not significantly influenced by plant extracts.
在分批培养中研究了薰衣草和问荆干提取物以及问荆中存在的类黄酮异槲皮苷对瘤胃微生物体外发酵的短期作用。三种试验日粮中果园草干草与大麦的比例按干物质计分别为100:0、75:25、50:50。除异丁酸外，所有挥发性脂肪酸的产生率都受到日粮组成的强烈影响，在较小程度上还受到植物提取物的影响，且这两个因素之间存在显著的相互作用。当干草是唯一底物时，添加薰衣草和问荆可使发酵率提高50%，这是通过增加乙酸盐和丙酸盐的释放实现的。相反，对于其他两种日粮，异槲皮苷会使发酵率大幅降低。植物提取物对气体产量没有显著影响。
