摘要

摘要。本研究的目的是研究黑曲霉浓度水平和不同程序的长时间对粗纤维含量、粗纤维肥力和短期体外发酵能力的影响。该实验使用3次重复的完全随机3x3因子模式(RALF)进行设计。发酵使用具有3个浓度水平(A0:0%、A1:2.5%和A2:5%)和3个长计划(T0:0天、T1:2天和T2:4天)的黑曲霉。测试的变量是粗纤维含量、粗纤维肥力、部分挥发性脂肪酸(VFA)如乙酸、丙酸盐、丁酸盐和总VFA。在表格中对数据进行了分析,然后进行了邓肯双郡测试。研究表明,在粗纤维含量、粗纤维肥力和黑曲霉保护的体外短期发酵能力方面,不同程序的启动水平和长时间存在交互作用(p0.05)。在组合A2T2处理中,粗纤维率最低(20.12%),粗纤维密度最高(41.00%),部分VFA升高最高,包括乙酸(58.40%)、丙酸盐(26.16%)、丁酸盐(12.73%)和总VFA最高(95.33%)。根据研究结果,黑曲霉启动水平行为和旧调度相结合可以提高粗纤维的肥力、部分VFA产量和总VFA产量,并减少粗短纤维。粗纤维智能化、部分VFA产生和最佳的总VFA,以及最低的粗纤维bonggol含量发生在A2T2处理与使用5%水平的黑曲霉和长4天程序的组合中。[UNK][UNK](使用黑曲霉发酵木薯棒的粗纤维含量、粗纤维消化率和可发酵性)[UNK]ABSTRAK。本研究的目的是确定黑曲霉水平和发酵时间对体外木薯棒粗纤维含量、粗纤维消化率和发酵能力的影响。本实验采用完全随机设计,采用3x3析因模式和3次重复。发酵使用3个黑曲霉水平(A0:0%、A1:2.5%和A2:5%)和3个持续时间(T0:0天、T1:2天和T2:4天)。观察到的变量是粗纤维含量、粗纤维消化率、包括乙酸盐、丙酸盐和丁酸盐的部分挥发性脂肪酸(VFA)以及总VFA。使用方差分析对数据进行分析,然后进行邓肯多区域检验。结果表明,不同发酵剂水平和发酵时间对木薯棒粗纤维含量、粗纤维消化率和可发酵性有交互作用(p0.05)。A2T2处理组合的粗纤维含量最低(20.12%),粗纤维消化率最高(41.00%),乙酸盐(58.40%)、丙酸盐(26.16%)和丁酸盐(12.73%)含量最高,总VFA最高(95.33%)。部分VFA和总VFA,以及降低木薯棒的粗纤维含量。粗纤维消化率、部分VFA和总VFA的最高水平以及最低的粗纤维含量出现在A2T2处理的组合中,使用5%水平的黑曲霉,发酵时间为4天。
