The effects of the use of Lactobacillus plantarum on silage quality in hungary vetch and rye mix silages

This thesis was carried out to determine the effects of Lactobacillus plantarum (LP) inoculation on silage quality, fermentation, aerobic stability and microorganism growth in silages obtained from Hungarian vetch and rye fodder plants alone or from their mixtures. The research groups were formed as Hungarian vetch control (MF), rye control (Ç), Hungarian vetch + rye control (MFÇ), Hungarian vetch + LP (MFLAB), rye + LP (MLAB), Hungarian vetch + rye + LP (MFÇLAB). Lactobacillus plantarum lactic acid bacteria was added to the silages at a rate of 1x109 cfu/g. The research groups were formed with a total of 30 silages, 6 groups, 5 replications. The prepared silages were stored in a laboratory environment at 23 ± 2 ºC for 90 days. Chemical, physical and microbiological analyzes were applied to the silages opened at the end of the ensiling period. The silages, whose opening processes were completed, were subjected to a 5-day aerobic stability test. When the findings obtained as a result of the research are examined, it is possible to say that the use of LP does not have the expected effect on the lactobacilli density in silages, but it is effective in reducing the pH1 (pH value after opening) and pH2 (pH value after aerobic stability) ratios and, accordingly, preventing the growth of undesirable microorganisms.
