Effect of different dry matter and biological additives application on fermentation process in red clover silages

Abstract

Influence of dry matter and application of biological silage additive on the basis of Live system on fermentation process in produced silages was studied in experiment with red clover. It was found out that with increasing amount of dry matter and application of silage additive improved parameters of fermentation process in produced silages. Fermentation process of feed ensilaged with lower dry matter content (27.92 %) was more intensive than of feed with higher content of dry matter (43.32 %). The greatest effect of application of biological additive was observed with ensilaging the feed with content of dry matter 42.32 %. During conservation of silage with higher content of dry matter was observed also the lowest level of proteolysis. Treated silages had lower pH, higher content of lactic acid, lower content of acetic and butyric acid, and % NH3-N of total N compared with non-treated silages.
