Wilted first cut timothy meadow fescue grass (DM 298 g/kg) was ensiled into pilot scale silos (3 kg) for 110 days in three replicates. Eight treatments were 1) Untreated (UT), 2) Formic acid based additive 5 1/t (FA), 3-5) Lactobacillus plantarum VTT E-78076 (E76) at three levels: 1*105 cfu/g, 5*105 cfu/g. E76 1*106 cfu/g, and 6-8) the three levels of E76 in combination with 0.30 g/kg K-sorbate. Fermentation quality of the silages was analysed and aerobic stability measured. All inoculants improved fermentation quality compared to untreated silage. Increase in inoculation rate resulted in a small increase in WSC and decreased amounts of ethanol and ammonia-N. K-sorbate had a negligible effect on fermentation quality while it improved aerobic stability especially with the highest E76 level.
