Abstract
The article presents the features of conservation of leafy mass of high-protein crops of the legume family, the disadvantages of traditional preparation of biomass for silage in fodder production. The results of studying the possibility of reducing plant moisture by mechanical means, using the press residue as a raw material for making haylage, and brown juice as a preservative are presented. The results of the development of a method for silage of the pressed alfalfa residue with the introduction of fermented brown juice enriched with the metabolic products of lactic acid and propionic acid bacteria - organic acids, to intensify the process of fermentation of feed. The analysis of the chemical composition of plant raw materials and the obtained haylage was carried out, the value of fodder, energy value and potential harmlessness for feeding to animals was determined.
Highlights
An important reserve of raw materials for the production of fodder protein is organic waste of agricultural field cultivation [1]
After separation of the protein fraction, which is used to prepare the feed additive - protein green concentrate (PGC), brown juice remains, which is usually considered as a production waste and is discharged together with the wash water
The introduction into the biomass of the pressed alfalfa residue of brown juice fermented with a mixture of strains of lactic acid and propionic acid bacteria activated and intensified the process of fermentation of the feed
Summary
An important reserve of raw materials for the production of fodder protein is organic waste of agricultural field cultivation [1]. Their insufficient use as raw materials for obtaining animal feed leads to an unjustified overconsumption of grain used for forage purposes. Field crop waste has many disadvantages - it requires additional processing, has high humidity, insufficient nutritional value, or contains unwanted components. These disadvantages can be avoided by receiving fodder from the waste of processing of green leaf-stem mass of ordinary and perennial seeded forage legumes. The task of developing methods and technological methods for the disposal of wastes from the processing of agricultural plants to obtain fodder products with high palatability, digestibility and nutritional value is urgent.
