摘要
The possibilities of using high-quality forages in incorporation with total mixed ration (TMR) during the fattening period of beef cattle have been investigated. A total of 30 Simmental bulls (438.94 ± 11.45 kg) were selected and randomly divided into two groups, TMR with single corn silage (SS) and TMR with various silage (MS). The whole experiment consisted of 15 days preparation period and 69 days experimental period. Rumen fluid and blood samples were taken from six beef cattle per treatment at the end of the experiment. The results showed that the average daily gain of the MS group (1.56 kg/day) was higher than (p p p p Prevotella-1 and Verrucomicrobia were higher in the MS group than the SS group (p < .05). An increase in the flavonoid biosynthesis was detected in the MS group compared with the SS group by Kyoto Encyclopaedia of Genes and Genomes analysis. The present findings suggest that it is economical and healthy to substitute high-quality forage +low level of concentrate for a relatively low proportion forage +high level of concentrate in a finishing diet of beef cattle, which was a feasible and healthy strategy in the intensive feeding system.

研究了在牛牛的育肥期间使用高质量饲料在牛肉牛育时的总混合配给（TMR）中的可能性。选择了30分钟（438.94±11.45千克）并随机分为两组TMR，用单玉米青贮（SS）和TMR，具有各种青贮饲料（MS）。整个实验包括15天的制备期和69天的实验期。在实验结束时从六个牛肉牛采取瘤胃和血液样品。结果表明，MS组（1.56千克/天）的平均日益增长高于（PPPP PREVOTLA-1和MS组的PPPP PVERICICIA高于SS组（P <.05）。黄酮类化合物增加与基因组和基因组分析的Kyoto Enclocopaedia与SS组相比，在MS组中检测到生物合成。本研究结果表明，替代高质量的饲料+低级浓缩物，以实现相对较低的比例+高牛肉牛精矿浓缩水平，这是一种强化饲养系统中可行和健康的策略。
