20.500.12556/DKUM-82996 Vpliv silirnih dodatkov na obstojnost in kakovost koruzne silaže diplomsko delo The influence of silage additives on corn silage stability and quality Na kmetiji Vivod smo septembra 2020 izvedli poskus s siliranjem koruze. V diplomskem delu smo primerjalno proučili vpliv različnih silirnih dodatkov (Schaumann Bonsilage SPEED M, Animalis SiloSolve FC, Biomin) na obstojnost in kakovost koruzne silaže. Kakovostne parametre smo ovrednotili spomladi leta 2021 s pomočjo organoleptične ocene po DLG ključu (vonj, barva, struktura, plesnivost, suho snov (SS) in neto energijo za laktacijo (NEL)) ter s kemijskimi analizami (aerobna stabilnost, vsebnost SS, škroba (ŠK), surovih beljakovin (SB), surovih vlaknin (SV), surovih maščob (SM), NDF, ADF, NEL …), izvedenimi v laboratoriju LKS – Landwirtschaftliche Kommunikations und Servicegesellschaft mbH (Niederwiesa, Nemčija). Na osnovi rezultatov ugotavljamo, da je bila aerobna stabilnost pri vseh silažah (z in brez silirnega dodatka) enaka (5 dni) ter da so med silažami po vsebnosti SB, SV in SP manjša odstopanja. Po oceni organoleptičnih lastnosti koruzne silaže so vrednosti vseh proučevanih parametrov statistično primerljive. Razen za vonj, barvo in NEL, kjer ugotavljamo statistično značilne razlike. In September 2020, an experiment was conducted with ensiled corn at the Vivod farm. The influence of different silage additives (Schaumann Bonsilage SPEED M, Animalis SiloSolve FC, Biomin) on the stability and quality of corn silage were compared. The quality parameters were evaluated in spring 2021. The organoleptic evaluation was performed according to the DLG key (smell, colour, structure, moldiness, dry matter (DM) and net energy for lactation (NEL)) and chemical analyses (aerobic stability, content of DM, starch, crude protein (CP), crude fibber (CF), crude fat (CF), NDF, ADF, NEL, ...) were carried out in the laboratory of LKS -Landwirtschaftliche Kommunikations und Servicegesellschaft GmbH (Niederwiesa, Germany). Based on the results, it could be concluded that the aerobic stability of all silages (with and without ensiling additive) was the same (5 days) and that there are minor differences between the silages in terms of CP, CF, and crude ash content. According to the evaluation of the organoleptic properties of corn silage, the values of all studied parameters are statistically comparable, except for the smell, colour, and NEL, where we find statistically significant differences. koruzna silaža silirni dodatki kakovost obstojnost corn silage silage additives quality stability true true false [M.
