Abstract


We observed the influence of silage additives for choice qualitative parameters at clover-grass silages in working conditions. We evaluated total classification and categorization to quality classes according to fermentative process. It has been found out positive effect of the silage additives for fermentative class and for total silage quality of silages. This positive effect has been more considerable at the classification to the fermentative classes at clover-grass silages. The high content of crude fibre decreased fermentative results and total silage quality at test clovergrass silages. The greatest (deterioration) influence for clasification to total quality class has crude fibre content. It is see from correlation coefficient at clover-grass silages r = 0.75 (P < 0.05). The weak dependence r = 0.37 (P < 0.05) was detected between fermentative class and acetic acid content. It was detected large dependence between fermentative class and butyric acid content r = 0.73 (P < 0.05). The silages with additives had better degree of proteolysis and higher value of lactic acid. The additive improved fermentative quality. The result of better fermentative process was reduction of crude fibre values with maintainance of energy content.
