摘要
将啤酒糟和麦芽根按不同比例袋装混贮,分别在30、60、90、120 d开袋取样进行感官评定,pH值、氨态氮、干物质、粗蛋白、中性洗涤纤维及有机酸含量分析。结果表明:混贮时间和水分含量均对混贮效果有显著影响;混贮饲料在混贮前60 d各指标变化范围较大,60 d后变化范围较小,并逐渐趋于稳定状态;混贮饲料以含水量50%的袋装混贮效果最好,其次是60%、40%,70%最差。
Mixed wet silage of BSG and malty root with diffent proportion in bag for 30, 60, 90, 120 days, then sensory value and NH3-N, pH, DM, CP, NDF and organic acid were analysed. Results showed that there were significant difference for different time or moisture. There were bigger variation range in 60 days of wet silage in compafision with that after 60 days for all determined target, and then, mixed silage tend to stable estate. Mixed silage feed with 50% moisture was the best, the next were 40% and 60%, 70% is the worst.
