UTICAJ INOKULACIJE NA KVALITET FERMENTACIJE I HEMIJSKI SASTAV SILAŽE LUCERKE

Abstract

In order to assess the impact of the inoculant "BioStabil Plus" on the ensiling process of alfalfa, the parameters of fermentation quality were analyzed (pH, acetic, butyric, lactic acid, ammonia and water-soluble nitrogen in total nitrogen) and chemical composition of silage (crude protein, crude cellulose, crude fats, nitrogen-free extractives and ash), as well as silage quality assessment (DLG and Zelter). Alfalfa biomass in the beginning of flowering phase was ensiled without additives and with the addition of inoculant. The addition of inoculant showed a decrease in pH, increased production of lactic acid, reduced production of acetic acid, with a favorable ratio of these acids (2-3: 1). The introduction of inoculants resulted in improved fermentation quality, which resulted in better preservation of nutrients, especially for crude proteins, since the use of inoculants also showed a decrease in ammonia nitrogen content compared to control (inoculation - 12.28% NH3-N/ΣN, control - 17.42% NH3-N/ΣN). The general conclusion is that inoculant should be added to alfalfa biomass, for the purpose of optimal production of lactic and acetic acid, as well as obtaining higher nutritional value.
