摘要
This study was conducted to evaluate effects of traditional Chinese medicine formula (TCMF) combined with several herbs on ruminal fermentation, enzyme activities and nutrient digestibility. Twenty finishing bulls were assigned to control or different TCMFs (Yufeisan‐1, ‐2, ‐3; 2.5% dry matter (DM) in concentrate). Results showed that DM intake was higher (P < 0.05) in the Yufeisan‐3 group than others. Compared to control, apparent digestibility of crude protein and neutral detergent fiber were increased (P < 0.05) by Yufeisan‐3. No changes were observed in ruminal pH, concentrations of ammonia‐N, microbial crude protein and total volatile fatty acid, whereas ratio of acetate to propionate was lower (P < 0.05) and propionate proportion tended to be higher (P < 0.1) in three TCMFs than control. Ruminal xylanase (P = 0.061) and carboxymethylcellulase (P < 0.05) activities were higher in Yufeisan‐3 than control. No changes were observed in abundance of total bacteria, fungi and protozoa, whereas Fibrobacter succinogenes (P = 0.062) and Ruminococcus flavefaciens (P < 0.05) were increased and total methanogens was reduced (P = 0.069) by Yufeisan‐3 compared to control. Yufeisan‐3 improved nutrient digestibility and ruminal enzyme activity, and modified fermentation and microbial community, maybe due to the presence of Herba agastaches, Cortex phellodendri and Gypsum fibrosum.

本研究旨在评估传统中药配方（TCMF）与几种草药配伍对瘤胃发酵，酶活性和营养物质消化率的影响。将20头最后的公牛分配给对照或不同TCMF（浓缩物中的Yufeisan-1，-2，-3; 2.5％干物质（DM））。结果显示，DM摄入量较高（P 0。05）在Yufeisan-3组比其他人。与对照相比，Yufeisan-3增加了粗蛋白和中性洗涤纤维的表观消化率（P 0.05）。瘤胃pH值，氨氮，微生物粗蛋白和总挥发性脂肪酸浓度没有变化，而醋酸盐与丙酸盐的比例较低（P 0。05），丙酸比例在三个TCMF中均高于对照组（P 0.1）。瘤胃木聚糖酶（P \x3d 0.061）和羧甲基纤维素酶（P 0。05）在Yufeisan-3中的活动高于对照。在细菌，真菌和原生动物的丰度方面没有观察到变化，而产琥珀酸纤维杆菌（P \x3d 0。062）和瘤胃球菌（P 0.05）增加，并且与对照相比，由Yufeisan-3减少总产甲烷菌（P \x3d 0.069）。Yufeisan-3提高了营养物质的消化率和瘤胃酶活性，改良了发酵和微生物群落，可能是由于藿香的存在，Cortex phellodendri和石膏纤维。
