摘要
Peanut vine is a typical peanut by-product and can be used as a quality roughage resource. Whole-plant corn silage is a commonly used roughage. However, few studies have investigated the effects of diets combining peanut vine and whole-plant corn silage on growth performance, antioxidant capacity, meat quality, rumen fermentation and microbiota of beef cattle. To investigate these effects, eighty Simmental crossbred cattle (body weight, 451.27 ± 10.38 kg) approximately 14 months old were randomly divided into four treatments for a 90-day feeding experiment. A one-way design method was used in this experiment. According to the roughage composition, the cattle were divided into a control treatment of 45% wheat straw and 55% whole-plant corn silage (WG), and three treatments of 25% peanut vine and 75% whole-plant corn silage (LPG), 45% peanut vine and 55% whole-plant corn silage (MPG), and 65% peanut vine and 35% whole-plant corn silage (HPG), and the concentrate was the same for all four treatment diets. The results showed that compared to the WG group, the MPG group experienced an increase in their average daily feed intake of 14%, an average daily gain of 32%, and an increase in SOD activity in the spleen of 33%; in the meat, dry matter content increased by 11%, crude protein by 9%, and ether extract content by 40%; in the rumen, the NH3-N content was reduced by 36%, the relative abundance of Firmicutes increased, and the relative abundance of Bacteroidetes decreased (p < 0.05). These results showed the composition of 45% peanut vine and 55% whole-plant corn silage in the roughage improved growth performance, antioxidant capacity, meat quality, rumen fermentation, and microbiota of beef cattle.

花生藤是一种典型的花生副产品，可以用作优质的粗糙资源。全植物玉米青贮饲料是一种常用的粗糙。然而，很少有研究研究了将花生藤和全植物玉米青贮饲料结合的饮食对生长性能，抗氧化能力，肉质，瘤胃发酵和肉牛菌群的影响。为了研究这些作用，将八十个西门特杂交牛（体重，451.27±10.38 kg）大约14个月大。该实验使用了一种单向设计方法。根据粗糙的成分，将牛分为45％小麦稻草和55％全植物玉米青贮饲料（WG）的对照处理，三种治疗25％花生藤和75％全植物玉米卷（LPG）的治疗方法，45％的花生藤和55％的全植物玉米青贮饲料（MPG）和65％的花生藤和35％的全植物玉米青贮饲料（HPG），并且所有四种治疗饮食的浓缩物均相同。结果表明，与WG组相比，MPG组的平均每日饲料摄入量增加了14％，平均每日增益为32％，脾脏的SOD活动增加了33％。在肉类中，干物质含量增加了11％，粗蛋白增加了9％，醚提取物含量增加了40％；在瘤胃中，NH3-N含量降低了36％，富公司的相对丰度增加，细菌植物的相对丰度降低（p <0.05）。这些结果表明，在粗糙度改善生长性能，抗氧化能力，肉质，瘤胃发酵和肉牛的菌群中，有45％花生藤和55％的全植物玉米青贮饲料的组成。
