Abstract: This thesis describes some observations of microbial metabolic activities that occur during the initial phase of aerobic deterioration of silages, which can affect their nutritional and hygienic quality. In vitro batch cultures were used to simulate aerobic processes that occur in these lactic acid-fermented feeds, with measurements of pH, organic acids and ethanol being used as indicators of change in metabolic activity. The use of selective antibiotics made it possible to draw conclusions on the causative microbial groups. An unexpected finding was the interaction and competition between two major bacterial and fungal representatives under semi-aerobic conditions.
