The study was completely randomized using four treatments with four replicates (silo) each. The treatments were as follows: C - control (forage without additives), NA - forage with low dose of natamycin (8 g/t) addition, LB - forage inoculated with low dose of L. buchneri (5 × 104 cfu/g) and NLB - forage treated with both natamycin (8 g/t) and L. buchneri (5 × 104 cfu/g). The losses of dry matter (DM) and gas, effluent production, chemical composition, yeast count and aerobic stability were calculated for all treatments. During fermentation, NLB produced more propionic and lactic acids and caused less DM and gas losses than other treatments (P < 0.01). The positive effect of NLB on yeast inhibition improved the aerobic stability of maize silage (P < 0.05). Thus, the combination of low doses of natamycin and heterolactic bacteria L. buchneri can reduce fermentative losses and improve the aerobic stability of maize silage after exposure to air. © 2020 Polish Academy of Science.
