摘要
This study aimed to determine the protein and carbohydrate fractions as well as the in situ rumen degradability of Brachiaria decumbens silage (BDS) supplemented with soybean hulls. Five soybean hull inclusion levels were used: 0, 10, 20, 30, and 40% of the fresh matter of B. decumbens grass, distributed into a completely randomized design with five replications. The inclusion of soybean hulls caused a linear decrease (p < 0.001) in carbohydrate fractions A + B1 and a linear increase (p < 0.001) in carbohydrate fraction C. The percentage of non-protein nitrogen fraction increased linearly (p < 0.001), but the nitrogen fractions B1 + B2 and B3 presented a negative quadratic effect (p < 0.01) with soybean hull level and fraction C presented a linear decrease (p < 0.001). The dry matter (DM) degradability of soluble fraction (A) and the undigestible DM decreased linearly (p < 0.01) with the soybean hull level. The potentially degradable water-insoluble portion (DM fraction B) and degradability rate (c) of the DM fraction B increased linearly (p < 0.001) with soybean hull level. The crude protein (CP) fraction A presented a linear increase (p < 0.001) with soybean hull inclusion; however, soybean hull levels caused a linear decrease (p < 0.001) in the CP level of fraction B. The degradable insoluble fraction of NDF (D) of the silage increased linearly (p < 0.001) and the indigestible NDF fraction of the silage was linearly decreased with the soybean hull level (p < 0.001). The inclusion of intermediate levels (20–30%) of soybean hulls provided better protein and carbohydrate fractions and better quality of BDS.

该研究旨在确定蛋白质和碳水化合物分数，以及补充大豆船体的Brachiaria depumbens青贮饲料（BDS）的原位瘤胃降解性。使用五种大豆壳包容水平：0,10,20,30和40％的B. Depumbens草的新物质，分布到完全随机化设计中，具有五种复制。包含大豆壳体在碳水化合物馏分A + B1中导致线性减少（P <0.001），碳水化合物馏分C的线性增加（P <0.001）。非蛋白质氮素级分的百分比线性增加（P <0.001），但氮级分B1 + B2和B3呈现阴性二次效果（P <0.01），大豆船体水平和馏分C呈现线性降低（P <0.001）。可溶性级分（A）的干物质（DM）可降解性和未抗原DM用大豆船体线性（P <0.01）降低。 DM级分B的潜在可降解的水不溶性部分（DM分数B）和可降解率（C）随大豆船体水平而线性地增加（P <0.001）。粗蛋白（CP）馏分A呈现线性增加（P <0.001），大豆壳夹杂物;然而，大豆船体水平在分数B的CP水平中引起线性减少（P <0.001）。青贮饲料的NDF（D）的可降解不溶性分数线性增加（P <0.001），并且青贮饲料的难以消化的NDF分数用大豆船体水平线性降低（P <0.001）。包含中间水平（20-30％）的大豆壳提供了更好的蛋白质和碳水化合物部分，更好的BDS质量。
