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±2şC 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.

Celem pracy było określenie wpływu inokulanta bakteryjnego na przebieg fermentacji, skład ścian komórkowych oraz stabilność tlenową kiszonek z kukurydzy. Kukurydzę zbierano w fazie 89. (BBCH). Zastosowany dodatek biologiczny zawierał w swoim składzie: Enterococcus faecium PCM 1858, Pediococcus acidilactici PAL-34, Lactobacillus plantarum PCM 493, Lactobacillus buchneri DSMZ 5987, Lactobacillus rhamnosus PCM 489, Lactobacillus brevis PCM488, Lactobacillus lactis PCM2379. Kukurydzę zakiszano w mikrosilosach laboratoryjnych wykonanych z PCV o pojemności 4 dm3 z możliwością odprowadzenia produktów gazowych. Mikrosilosy były składowane w warunkach laboratoryjnych w temperaturze 10–15±2şC. Próbki kiszonek do analiz mikrobiologicznych i chemicznych pobierano w 3., 14., 21. i 60. dniu po otwarciu mikrosilosów, a stabilność tlenową określano po 7 dniach napowietrzania. Uzyskane wyniki wskazują wpływ dodatku biologicznego na poprawę przebiegu fermentacji, obniżenie składników ścian komórkowych i poziomu deoksyniwalenolu (DON). Zastosowany dodatek biologiczny nie wpływał na poprawę stabilności tlenowej kiszonek podczas 7-dniowego napowietrzania.
