dc.description.abstractIn the experiment, forage from the 1st cut of meadow grasses mown at the heading stage of dominant grasses was ensiled. The control silages were made from fresh forage (dry matter 223.5 g×kg-1) and wilted forage (dry matter 351.9 g×kg-1). The experimental silages were made from fresh forages supplemented with a 5% water solution of lactic acid (0.5 and 0.7 l×100 kg-1 of forage) and 8% water solution of lactic acid (0.4 and 0.6 l×100 kg-1 of forage). The highest contents of crude protein, water-soluble carbohydrates and energy were found in silages supplemented with 5% lactic acid applied at 0.7 l×100 kg-1 of forage and in silages supplemented with 8% lactic acid applied at 0.6 l×100 kg-1 of forage. The above silage variants were also characterized by the lowest content of NH3-N in total-N, butyric acid and acetic acid, as well as the highest contents of lactic acid and the best indicators of fermentation quality. No important differences were found between silages made from wilted forage and silages made with lactic acid supplement.en
dc.description.abstractU istraživanjima korišćena mlečna kiselina kao dodatak silaži od smeše livadskih trava ( livadski vijuk, engleski ljulj i italijanski ljulj ukupno čine 85%, bele deteline 11% i ostalih krmnih vrsta 4%) se pokazala kao dobar hemijski preparat. Spravljena silaža sa ovim dodatkom naročito 5% dodate mlečne kiseline sa 0,7 l x 100 kg-1 mase i 8% mlečne kiseline dodavane 0,6 l x 100 kg-1 mase se karakterisala najvišim sadržajem sirovih proteina ugljenih hidrata rastvorljivih u vodi i energijom. Dodatak 8% mlečne kiseline u količini 0,6 l x 100 kg-1 mase je bilo najefikasnije u ograničavanju razlaganja proteina i pokazalo se kao povoljan inhibitor fermentiranja buterne i sirćetne kiseline u siliranoj biomasi smeše livadskih trava. U našem istraživanju nisu uočene značajne razlike između silaža spravljanih od provenute mase i silaže spravljane od sveže pokošene mase dopunjavane mlečnom kiselinom u pogledu sadržaja sirovih proteina energije kao i pokazatelja kvaliteta fermentacije. Iz svega navedenog zaključuje se da, u povoljnim atmosferskim uslovima, provenuta pokošena masa pre siliranja nastavlja da zadržava visok kvalitet silaže. Tamo gde nije moguće provenjavanje smeše livadskih trava ili gajenih trava preporučuje se da se silira masa sa dodatkom mlečne kiseline, pri čemu se dobijena silaža odlikuje niskim gubicima proteina i ugljenih hidrata rastvorljivih u vodi i visokim kvalitetom fermentacije silirane biomase.sr
