This study aimed to examine the effects of re-ensiling time and Lactobacillus buchneri on the fermentation profile, chemical composition and aerobic stability of sugarcane silages. The experiment was set up as a repeated measure design consisting of four air-exposure periods (EP)(0, 6, 12, and 24 h) microbial additive (A) (L. buchneri; or lack of there), with five replicates. Sugarcane was ground through a stationary forage chopper and ensiled in four plastic drums of 200-L capacity. After 210 days of storage, the drums were opened and half of the silage mass was treated with L. buchneri at the concentration of 105 cfu/g of forage. Subsequently, the silages were divided into stacks. The re-ensiling process was started immediately, at 0, 6, 12 and 24-hour intervals, by transferring the material to PVC mini-silos. Silos were opened after 120 days of re-ensiling. The use of L. buchneri reduced butyrate concentration but did not change ethanol or acetic acid concentrations and aerobic stability. An interaction effect between L. buchneri and re-ensiling time was observed for dry matter (DM) losses and composition. Lactobacillus buchneri is not effective in improving aerobic stability in re-ensiled sugarcane silages. However, less DM is lost in silages treated with L. buchneri and exposed to air for 24 h. Re-ensiling sugar cane in up to 24 h of exposure to air does not change final product quality.

布氏乳杆菌的重新青贮时间和应用会改变甘蔗青贮饲料的特性吗？

本研究旨在检验重新青贮时间和布氏乳杆菌甘蔗青贮饲料的发酵曲线、化学成分和有氧稳定性的研究。该实验设置为重复测量设计，包括四个空气暴露期（EP）（0、6、12和24小时）微生物添加剂（A）（布氏乳杆菌; 或缺乏那里），有五个重复。甘蔗通过固定的饲料切碎机研磨，然后装入四个容量为 200 升的塑料桶中。储存 210 天后，打开转鼓，一半的青贮饲料经过处理布氏乳杆菌浓度为 105cfu/g 饲料。随后，青贮饲料被分成堆叠。以 0、6、12 和 24 小时为间隔，通过将材料转移到 PVC 小型筒仓，立即开始重新青贮过程。重新青贮 120 天后打开筒仓。指某东西的用途布氏乳杆菌降低丁酸盐浓度，但不改变乙醇或乙酸浓度和需氧稳定性。之间的交互作用布氏乳杆菌观察干物质 (DM) 损失和组成的再青贮时间。布氏乳杆菌不能有效改善重新青贮的甘蔗青贮饲料的需氧稳定性。然而，经过处理的青贮饲料中的 DM 损失较少。布氏乳杆菌并暴露在空气中24小时。暴露在空气中长达 24 小时的甘蔗再青贮不会改变最终产品的质量。
