Abstract. This research was carried out to determine the effects of bacterial silage inoculant using as silage additives on the fermentation charakteristics, cell wall contents and aerobic stability of maize silages. Maize silage was harvested in the 89 (BBCH) developmental ripening stage. Biological additive was used as additive which contains Enterococcus faecium PCM 1858, Pediococcus acidilactici PAL-34, Lactobacillus plantarum PCM 493, Lactobacillus buchneri DSMZ 5987, Lactobacillus rhamnosus PCM 489, Lactobacillus brevis PCM 488, Lactobacillus lactis PCM 2379. Maize was ensiled in 4 dm3 special PCV laboratory microsilos with a cover permitting gaseous products. The microsilos were stored at 10–15±2ºC undr laboratory conditions. Microsilos from each group were sampled for microbiological and chemical analyses on the days 3, 14, 21 and 60 after ensiling, whereas aerobic stability was determined after 7 days. As a result, bacterial silage inoculant improved fermentation, decreased cell wall contents, deoxynivalenol (DON) concenration, do not improved aerobic stability of maize silage after 7 days exposure to air.
