The Efficiency of the Mixture of Sodium Nitrite, Sodium Benzoate and Potassium Benzoate in Aerobically Unstable Silages

Four types of various crops were used in a specific study to examine the effect of silage additive based on sodium nitrite, sodium benzoate and potassium benzoate on silage quality and aerobic stability of silages in particular. Ensiling condition was challenged by weak packing density of forage and by air ingression into silos. Additive treated silages were found to have a lower pH, reduced formation of ammonia-N and 2.3 butanediol and ethanol compared with untreated control silages. Significantly eliminated yeast growth was reflected in considerably increased stability of additive treated silages. The use of the silage additive provides sufficient guaranty of a required ensiling process and prolonged aerobic stability even under difficult ensiling condition.
