Sažetak

The aim of the study was selected macrominerals determination in alflalfa silages conserved by different silage additives and storage technologies. We conserved alfalfa from second cut, flowering
phenophase. In the trial we conserved alfalfa in three variants (UC:untreated control, A: variant with lactic acid bacteria addition, B: variant with lactic acid bacteria and complex of cellulases and hemicellulases addition). All of variants were conserved in silage units (SJ 750) and in silage bags. After the finish of fermentation process we found nonsignificant (P>0.05) differences in Ca, Na and K content in silage units SJ 750, the highest Ca content was detected in control variant UC (13.68 g.kg-1 of dry matter). Positive effect of additives application we found in P content (3.75 g.kg-1 of dry matter in variant B). After the application of silage additives we found singnificantly lower (P<0.05) Mg content in silage units. Non-significant differences in P, Na and K content were detected in
silage bags. The highest Ca content (12.22 g.kg-1 of dry matter) we determined in variant A (lactic acid bacteria addition). In variants A and B (silage additives application) we found higher P content. In comparison with untreated control, the highest Mg content (P<0.05) we found in variant with lactic acid bacteria addition (variant A). In comparison between variants ensiled in silage units and bags, we detected higher Na content in silages from silage units, significantly in control variant UC and variant B (P<0.05). Application of silage additives can influence some minerals content. This effect is positive from mineral nutrition view. In laboratory conditions conserved silages we found higher calcium, sodium and potassium content than in silages made in silage bag.
