Sažetak
This study was carried out to determine the effects of homofermentative lactic acid bacterial inoculant on the fermentation and aerobic stability of second crop maize silages. Maize was harvested at the milk stage. Inoculant -1174 (Pioneer®,USA) was used as homofermentative lactic acid bacterial inculant. Inoculant was applied 6.00 log10 cfu/g silage levels. Silages with no additive served as controls. After treatment, the chopped maize was ensiled in the PVC type laboratory silos. Three silos for each group were sampled for chemical and microbiological analysis on days 2, 4, 7, 14, 21, 28 and 56 after ensiling. At the end of the ensiling period, all silages were subjected to an aerobic stability test for 14 days. Neither inoculant improved the fermentation parameters of second crop maize silages. At the end of the ensiling period, inoculant increased lactobacilli and decreased yeast and mold numbers of silages. Inoculant treatment did not affect aerobic stability of silages.
