Influence of inoculation with Lactobacillus on fermentation, production of 1,2-propanediol and 1-propanol as well as Maize silage aerobic stability

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.
