abstract = "In the winter time in Serbia, maize silage is the main ruminant feed. Therefore, managing maize silage is an important contributor to maintain the silage quality for livestock feed. In the study were evaluated the chemical composition, energetic and fermentation characteristics in whole-crop maize silage inoculated with different bacterial inoculants under field conditions in the commercial dairy farm, during the 2015. Three treatments were tested: negative control (untreated silage), a positive control (competitor inoculant) and Silko treatment (contains a mixture of 4 strains of Lactobacillus plantarum (LP1, LP2, LP3 and LP4). Maize is ensiled in the milk-wax grain maturity. After 90 days of ensiling, the maize silages were analyzed. The application of bacterial inoculants improved the chemical composition and energetic characteristics of silage. The inoculant Silko was more effective at improving the fermentation characteristics than competitor inoculant. Ash, cellulose, soluble N/TN, NH3-N/TN, ADF, NDF, acetic acid and pH were significantly lower in Silko treatment than positive control. There were no differences in crude fat, crude protein, ME, NEL, lactic acid and butyric acid between the treated silages. Generally, the new product bacterial inoculant Silko proved in field trials its ability to support the ensiling process in maize. The main action of the bacterial inoculant Silko is performed in two ways: the reduced degradation of protein in silage and the improvement of the aerobic stability due to the lower pH, higher content of acetic acid than negative control., U zimskom periodu u Srbiji, silaža kukuruza je glavna hrana za preživare. Zbog toga je postupak proizvodnje silaže važan faktor u očuvanju kvaliteta silaže za ishranu zivotinja. U studiji su ocenjeni hemijski sastav, energetske i fermentacione karakteristike silaža od celih biljaka kukuruza inokulisanih različitim bakterijskim inokulantima u terenskim uslovima na komercijalnoj farmi goveda u 2015. godini. Tri tretmana su testirana: negativna kontrola (netretirana silaža), pozitivna kontrola (konkurentski proizvod) i Silko tretman (sadrži mešavinu 4 soja Lactobacillus plantarum (LP1 LP2, LP3 i LP4)). Kukuruz je siliran u fazi mlečno-voštane zrelosti zrna. Silaža je analizirana 90 dana nakon siliranja. Bakterijski inokulanti su poboljšali hemijski sastav i energetske karakteristike silaže. Inokulant Silko bio je efikasniji u poboljšanju fermentacionih karakteristika u odnosu na konkurentski proizvod. Sadržaj pepela, celuloze, rastvorljivog i amonijačnog azota u ukupnom azotu, ADF, NDF, sirćetne kiseline i pH značajno su niži u Silko tretmanu nego u pozitivnoj kontroli. Nije bilo razlike u sadržaju sirove masti, sirovih proteina, ME, NEL, mlečne i buterne kiseline između tretiranih silaža. Generalno, novi proizvod bakterijski inokulant Silko pokazao je da u poljskim ogledima ima sposobnost da podrži proces siliranja kukuruza. Delovanje bakterijskog inokulanta Silka vrši se na dva načina: smanjena degradacija proteina u silaži i poboljšana aerobna stabilnost zbog nižeg pH i većeg sadržaja sirćetne kiseline u poređenju sa negativnom kontrolom.",
