Contemporary silage additives

Abstract

The overview of additives used in silage preparation is presented in the paper. Those most present around the world these days are biological additives (bacterialenzymatic inoculants). They are used to enhance the fermentation in the plant material which is difficult to ensile (leguminous), and also in order to increase aerobic stability in maize silage (which is the most common in our country). Aside from those mentioned, also the additives based on zeolite are intensively investigated in Serbia. The obtained results show the decrease in some mycotoxin contents in silages with the zeolite added. It is also confirmed that those additives decrease proteolytic activity, which is particularly important in maize silage with urea added.

U radu je dat pregled aditiva koji se danas najviše koriste pri siliranju. Najaktuelniji su, širom sveta, biološki dodaci (bakterijsko-enzimski inokulanti). Koriste se radi intenzifikacije fermentacije u biljnom materijalu koji se teže silira (leguminoze), kao i u cilju povećanja aerobne stabilnosti kukuruzne silaže (najčešće spremana vrsta slaže kod nas). Osim ovih dodataka, u Srbiji se nekoliko godina intenzivno ispituju aditivi na bazi zeolita. Dobijeni rezultati govore o smanjenju količine nekih mikotoksina u silaži sa dodatim sredstvima na bazi zeolita. Pored toga, dokazano je i smanjenje proteolitičkih procesa, što je naročito bitno za silaže kukuruza sa dodatom ureom.
