Abstract The aim of this study is to determine the influence of a commercial bacterial inoculant (L1) and a preparation (L2) containing three Lactobacillus strains capable of producing 1,2-propanediol and short-chain fatty acids on maize silage aerobic stability improvement. The research showed that during 90-day ensilage, the applied preparations significantly reduced the content of DM, water-soluble carbohydrates (WSCs), pH and DM recovery (P < 0.05). The concentration of lactic acid (LA), acetic acid (AA) and propionic acid (PA) in the inoculated samples increased significantly (P < 0.05). 1,2-Propandiol and 1-propanol were not found in control silages (without additives). The addition of L1 and L2 significantly (P < 0.05) increased the concentration of these substances. The L1 and L2 mixtures significantly extended (P < 0.05) the silage aerobic stability.

接种乳酸杆菌对发酵、1,2-丙二醇和1-丙醇生产以及玉米青贮有氧稳定性的影响

摘要 本研究的目的是确定商业细菌接种剂 (L1) 和含有三种能够产生 1,2-丙二醇和短链脂肪酸的乳杆菌菌株的制剂 (L2) 对玉米青贮有氧稳定性改善的影响。研究表明，在 90 天的青贮期间，施用的制剂显着降低了 DM、水溶性碳水化合物（WSCs）、pH 和 DM 回收率的含量（P < 0.05）。接种样品中乳酸（LA）、乙酸（AA）和丙酸（PA）的浓度显着增加（P < 0.05）。在对照青贮饲料（无添加剂）中未发现 1,2-丙二醇和 1-丙醇。L1 和 L2 的添加显着 (P < 0.05) 增加了这些物质的浓度。L1 和 L2 混合物显着扩展（P < 0.
