Energy-saving technology of high-protein silage preservation

The rationale for the present study is explained by the need of Russian and foreign agricultural producers in high-protein feed preservation efficiency increase and nutrients loss decrease, as well as implementation of energy-saving technologies. Currently, there is lack of research data on utilization of chemical and bacterial agents for silage preservation. There is no definite opinion on vacuum influence on fermentation processes during ensilaging and on qualitative parameters of silage. The aim of the study was to give grounds for technological processes of biocombined chemical conservant Tecacid and biological agent Biosil-NN utilization, as well as improvement of Eastern galega conservation technology for increase of qualitative parameters and energy management efficiency. Laboratory and production trials, performed during this study, showed that optimal and most efficient approach was silage two-phase combined treatment with Tecacid (1.5 L/ton) and Biosil-NN (1 L/40 ton). Consecutive processing of galega forage ensilaging contributed to increase of fermentation quality and preservation of nutrients regardless of anaerobiosis production techniques. When vacuum sealing was used instead of conventional method of sealing, total content of acids, including lactic and oleic, decreased, which improved fermentation quality. Materials of this article are of practical value for feed producers involved in high-protein silage preservation, because the obtained results proved high efficiency of two-phase combined application of chemical and bacterial agents.
