Abstract (PL)
Celem pracy byĆo zbadanie wpĆywu komercyjnego inokulantu bakteryjnego CL (Lactobacillus plantarum K KKP/593/p, L. plantarum C KKP/788/p, Lactobacillus brevis KKP 839, Lactobacillus buchneri KKP 907) oraz preparatu M3 (L. buchneri ATCC 4005, Lactobacillus diolivorans LGM 19667, Lactobacillus reuteri ATCC 23272) na wybrane parametry kiszonki z kukurydzy. Badana kiszonka zostaĆa przygotowana w minisilosach laboratoryjnych. Podstawowy skĆad paszy okreĆlono metodÄ
AOAC. StabilnoĆÄ tlenowÄ
mierzono jako czas potrzebny do podwyĆŒszenia temperatury kiszonki o â„2°C w stosunku do temperatury otoczenia. StÄĆŒenie 1-propanolu i 1,2-propanodiolu w kiszonce oznaczono z zastosowaniem chromatografii gazowej. Na podstawie uzyskanych wynikĂłw stwierdzono, ĆŒe w ciÄ
gu 120 dni zakiszania zastosowane preparaty istotnie (p<0,05) obniĆŒyĆy pH, zawartoĆÄ suchej masy oraz cukrĂłw rozpuszczalnych w wodzie w porĂłwnaniu z kiszonkami kontrolnymi. StÄĆŒenie kwasu mlekowego, octowego i propionowego w prĂłbkach kontrolnych byĆo istotnie niĆŒsze w porĂłwnaniu z prĂłbkami traktowanymi inokulantem CL i M3. Dodatek CL i M3 spowodowaĆ istotny wzrost stÄĆŒenia 1,2-propanodiolu i 1-propanolu
w kiszonkach, obecnoĆci tych zwiÄ zkĂłw nie stwierdzono w kiszonkach kontrolnych. Ponadto zastosowane modyfikatory obniĆŒyĆy liczebnoĆÄ grzybĂłw pleĆniowych i grzybĂłw droĆŒdĆŒoidalnych oraz spowodowaĆy wzrost liczebnoĆci bakterii mlekowych w kiszonkach, a takĆŒe wydĆuĆŒyĆy ich stabilnoĆÄ tlenowÄ w porĂłwnaniu z kontrolÄ .

Abstract (EN)
The study aimed to investigate the effect of a commercial bacterial inoculant CL (Lactobacillus plantarum K KKP/593/p, L. plantarum C KKP/788/p, Lactobacillus brevis KKP 839, Lactobacillus buchneri KKP 907) and an M3 preparation (L. buchneri ATCC 4005, Lactobacillus diolivorans LGM 19667, Lactobacillus reuteri ATCC 23272) on selected parameters of maize silage. The silage tested in the study was prepared in laboratory mini-silos. The basic composition of the feed was determined
using the AOAC method. Oxygen stability was measured as the time needed to increase the silage temperature by â„2°C of the ambient temperature. The concentration of 1-propanol and 1,2-propanediol in silage was estimated using a gas chromatograph. The results indicated that during 120 days of ensilage, the applied preparations significantly (p<0.05) reduced the pH and the content of dry matter, and water-soluble sugars in silages compared to the control silage. The concentration of lactic, acetic, and propionic acids in the control samples was significantly lower compared to the samples containing CL and M3. The addition of CL and M3 caused a significant increase in the concentration of 1,2-propanediol and 1-propanol in the silages, whereas these compounds were not found in the control silage. Furthermore, the applied inoculants reduced the number of mold fungi and yeast-like fungi and increased the number of lactic bacteria in the silages and also extended their aerobic stability compared to the control.
