Sažetak
The aim of this study was to determine the concentration of some mineral elements in conserved feeds. In the trial maize corn was treated with high moisture in 3 variants: variant UC (control) without additives, variant A (Lactobacillus rhamnosus, Lact. plantarum, Lact. brevis, Lact. buchneri, Pediococcus pentosaceus, 2,5x10 11 CFU.g-1) and variant B (Enterococcus faecium, Lact. plantarum, Lact. casei, Lact. buchneri, Pediococcus pentosaceus, 150x103 CFU.g-1) with biological additives. After silage fermentation the highest content Ca was found in the control variant UC (0.483 g.kg-1 of DM). The lowest P content (2.976 g.kg-1 of DM) was detected in inoculated variant A (with lactic acid bacteria addition). In the Mg content was found the same effect as in Ca and P content. After application of silage additives lower concentration of Mg (0.957 g.kg-1 of DM in variant A and 0.970 g.kg-1 of DM in variant B) was determined. The Na concentrations were between 0.480 g.kg-1 of DM (variant B) and 0.711 g.kg-1 of DM (untreated control variant UC), significant differences were found between variants UC and B, as well as between A and B (P<0.05). The highest K concentration was found in variant A (conserved by biological inoculant), 4.039 g.kg-1 of DM. The concentration of K in experimental variant B was the lowest (3.716 g.kg-1 of DM). Differences between experimental variants (A, B) were significant (P<0.01). After application of the silage additives to high moisture corn in silages lower Ca, P, Mg and Na content was determined.
