Title : THE INFLUENCE OF INOCULATION ON CHEMICAL COMPOSITION, QUALITY AND PROTEOLYSIS IN SILAGES MADE FROM WHOLE MAIZE PLANT AND ALFALFA
Abstract : The paper presents the results for ensiling of the whole maize plant alone or in mixing with alfalfa. In this experiment maize FAO maturity group 600 and alfalfa at the end of butonization phase (wilted material with 390 gkg-1 dry matter), was used for ensiling. The experiment was organized as two-factorial (32), with three replications, where factor A was the different amount of alfalfa (A1=0%, A2=15%, A3=30%,) and factor B was inoculation (B1= no inoculant, B2= with inoculant). All silages after the treatment were compressed in plastic experimental siloses with volume of 60 dm3. After 56 days the experimental siloses were opened and representative samples were taken for chemical analyses. Chemical composition and silage quality were analysed in the Laboratory for nutrition of domestic animals on the Faculty of Agriculture of the University of Belgrade. Statistical analysis was performed by software Statsoft (2006), where the analysis of variance examined the significance of the factors. Along with the increase of the share of alfalfa in silages, there was increase of crude proteins, lipids, cellulose, ash, pH value and production of ammonia, with the decreasing share of NFE (p<0.05). In treatments with inoculant increase in amount of lactic acid was noticed, as well as lower amount of ammonia nitrogen and acetic acid, which can be significant for aerobic stability of silage. All silages, with a slight variation in the point number, were ranked in the 1st quality class according to the Flieg method.
