以学术标准将括号内的段落翻译为英文百脉根的干物质、酸性洗涤纤维和粗蛋白的表观消化率高于苜蓿燕麦干草这表明百脉根更容易被湖羊吸收。此外百脉根缩合单宁通过提高湖羊的抗氧化酶活性和免疫因子的浓度来增强抗氧化能力和免疫能力。研究还发现百脉根缩合单宁降低了瘤胃中蛋白降解菌和纤维降解菌的活性从而降低了瘤胃的发酵性能。然而缩合单宁抑制了产甲烷菌的活性减少了甲烷的生产提高了能量利用效率从而保证了湖羊的健康生长。总

The apparent digestibility rates of dry matter, acid detergent fiber, and crude protein in Astragalus root were higher than those in alfalfa oat hay, indicating that Astragalus root is more easily absorbed by Hu sheep. In addition, condensed tannins in Astragalus root enhance antioxidant and immune capacities in Hu sheep by increasing the activity of antioxidant enzymes and the concentration of immune factors. The study also found that condensed tannins in Astragalus root reduce the activity of proteolytic and fibrolytic bacteria in the rumen, thereby decreasing ruminal fermentation. However, condensed tannins inhibit the activity of methanogenic bacteria, reducing methane production and improving energy utilization efficiency, thus ensuring the healthy growth of Hu sheep. Overall, this study suggests that Astragalus root plays a role in improving growth performance, enhancing antioxidant capacity, and immune ability in Hu sheep, but further research is needed to determine the precise concentration for its use.
