摘要
This study aimed to investigate the effects of dietary tannic acid (TAN) on the gas production, growth performance, antioxidant capacity, rumen microflora, and fermentation function of beef cattle through in vitro and in vivo experiments. TAN was evaluated at 0.15% (dry matter basis, DM) in the in vitro experiment and 0.20% (DM basis) in the animal feeding experiment. The in vitro results revealed that compared with control (CON, basal diet without TAN), the addition of TAN significantly increased the cumulative gas production and asymptotic gas production per 0.20 g dry matter substrate (p 2.50, p 2.50, p < 0.05), while the relative abundance of Prevotellaceae in rumen microbial community was significantly decreased (p < 0.05) as compared to that of the CON group. In conclusion, the dietary supplementation of TAN could improve the growth and slaughter performance and health status of beef cattle, and these favorable effects might be attributed to its ability to alleviate liver lipid peroxidation, enhance glucose metabolism, and promote a balanced rumen microbiota for optimal fermentation.

这项研究旨在研究饮食单宁酸（TAN）对通过体外和体内实验的饮食生产，生长性能，抗氧化能力，瘤胃微生物和发酵功能的影响。在体外实验中以0.15％的0.15％（干物质，DM）评估TAN，在动物喂养实验中评估0.20％（DM）。体外结果表明，与对照（con，无棕褐色的基础饮食）相比，棕褐色的添加显着增加了每0.20 g干物质底物的累积气体产生和渐近气的产生（p 2.50，p 2.50，p <0.05），与CON组相比，瘤胃微生物群落中普雷特拉开科的相对丰度显着降低（p <0.05）。总之，饮食补充量可以改善肉牛的生长和屠宰表现和健康状况，这些有利的影响可能归因于减轻肝脏脂质过氧化，增强葡萄糖代谢的能力，并促进均衡的Rumen Microbiota，以获得最佳的最佳瘤含量。发酵。
