Abstract

Results in ours study shown that mountain brome (Bromus marginatus Nees ex Steud, cv. Tacit) is grass with high content of fibre complex. At the end of elongation phase was content of crude fibre 278.7 g, and in phase full heading 342.8 g/kg DM. Content of crude protein decreased with maturation from 160.9 to 89.8 g/kg DM. The optimal cut time of this grass is end of elongation phenophase. Application of biological and biological-enzymatic additives markedly improved all fermentation parameters compared to untreated silage. In inoculated silages were lower losses of dry matter, pH value, content of alcohol, NH3 – N of total N, and higher acid concentrations than in untreated silage. The application of bacterial additives caused a decrease in the contents of crude fibre, ADF, and NDF. This positive effect was higher in silage treated with the biological-enzymatic additive as in silages treated with biological additives.
