The nutritive value and fermentation quality of palisadegrass (Brachiaria brizantha cv. Xaraes) and stylo (Stylosanthes capitata × S. macrocephala cv. Campo Grande) mixed silages were evaluated. The experiment was analyzed in a factorial scheme (5 × 2) in a completely randomized design using increasing levels of stylo (0, 25, 50, 75 and 100% on a fresh matter basis) on palisadegrass silages, with and without microbial inoculants (MI). With the increased ratio of stylo in mixed silages, dry matter (DM), crude protein (CP), acid detergent fiber (ADF), and lignin content increased in silages. The presence of MI promoted lower DM content, and higher neutral detergent fiber corrected for ash and protein, ADF and lignin content. The acid detergent insoluble nitrogen content and the lactic acid bacteria populations were not affected by treatments. The in vitroDM digestibility was affected by the interaction of levels of the stylo and MI. The pH, NH3 -N/total nitrogen and butyric acid concentrations decreased with increasing levels of stylo. Better nutritive value and quality of fermentation was found in the silage containing higher proportions of this stylo mixed with palisadegrass. The microbial inoculant evaluated did not alter the nutritive value or quality of the fermentation of the silages in this experiment.

木瓜和stylo混合青贮饲料的营养价值和发酵质量。

评估了木瓜（Brachiaria brizantha cv。Xaraes）和stylo（Stylosanthes capitata×S. macrocephala cv。Campo Grande）混合青贮饲料的营养价值和发酵质量。在阶乘方案（5×2）中以完全随机的设计对实验进行了分析，使用在木栅草青贮饲料中添加和不使用微生物接种剂的木耳青贮水平（按新鲜物质计分别为0、25、50、75和100％）（ MI）。随着混合青贮饲料中stylo比例的增加，青贮饲料中的干物质（DM），粗蛋白（CP），酸性洗涤剂纤维（ADF）和木质素含量增加。MI的存在促进了较低的DM含量，并且较高的中性洗涤剂纤维经灰分和蛋白质，ADF和木质素含量校正。酸性洗涤剂的不溶氮含量和乳酸菌种群不受处理的影响。探针和MI水平的相互作用影响了DM的体外消化率。pH，NH3-N /总氮和丁酸的浓度随探针水平的增加而降低。在青贮饲料中，含有较高比例的这种麦草和木瓜混合饲料，具有更好的营养价值和发酵质量。在该实验中，所评估的微生物接种剂没有改变青贮饲料的营养价值或发酵质量。
