Abstract

The article deals with the problems of preservation of leafy mass of legume family high-protein agricultural crops, the disadvantages of the crop high-temperature drying in fodder production. One presents the results of studying the possibility of reducing the moisture content in plants mechanically, using the resulting waste (press residues) as a raw material for silage preparation applying the energy-saving bioconversion method. The results of developing the method of alfalfa press residues ensilaging with introduction of a mixture of strains of lactic acid bacteria cultures are presented The chemical composition of the vegetable stock and resulting silage was analysed, the feed and caloric values were determined for introduction into animal diets.

Highlights

In conditions where competitiveness of the national economy need to be improved based on innovative development, the factors capable of influencing the transformation of the economic system are gaining currency
In experiments for silage preparation, one placed in storage the biomass made of wilted and pressed alfalfa green matter using anaerobic fermentation with the starter material made up of a mixture of lactic acid bacteria of Lactobacillus genus. These strains of lactic acid bacteria were selected based on the fact that their predominant amount is observed in different stages of ensilaging and has positive effect on the fodder fermentation rate at all stages of ensilaging [13]. These strains, in comparison with other microorganisms used for the preparation of starter materials applied in fodder production for its ensilaging, have a higher rate of reproduction, suppression of vital processes and limitation of the development of putrefactive bacteria and other undesirable bacterial population
It is known that lactic acid bacteria have antibiotic effect on putrefactive and other spore-forming bacteria found in silage and weaker antibiotic effect on the Echerichia coli group

Summary

Introduction

In conditions where competitiveness of the national economy need to be improved based on innovative development, the factors capable of influencing the transformation of the economic system are gaining currency. The energy-saving technologies, alternative energy sources, information and communication technologies, intellectual capital, knowledge-intensive industries may be such fundamentals of the innovative economic system. In this regard, the development of energy-saving technologies of integrated use of plant resources, full or partial disposal of the resulting wastes with preparation of multi-purpose products are getting of particular importance [2, 3]. The main purpose of drying technologies applied for fodder procurement is the dehumidification of the vegetable stock used but maximum preservation of properties of the contained substances The green massafter mowing and chopping becomes a favourable and available medium for development and accumulation of many species of microorganisms living on it - bacteria, yeast, mold and other microfungi, that during their living activities actively decompose nutrients contained in destroyed plant cells, which is the reason of decreased feed value of the biomass [4].
