The proposed feed additive enzyme-probiotic actions "Prostor", which has a probiotic, antibacterial, antiviral properties, provides an increase in diet digestibility and stimulation of metabolic and immune processes increases the commercial efficiency of use of feed rations. DBA Scope developed jointly with the Institute of ecology and evolution them. A. N. Severtsov Russian Academy of Sciences. The space's unique biotechnology; contains immobilized on the recommended to drink a therapist (adsorbed) live cells and metabolites of Bacillus: Bacillus subtillis strains (three strains), Bacillus licheniformis, complex lactic acid bacteria and products of their metabolism - a set of key enzymes - cellulase, methods, amylase, protease, lipase, organic acids, biologically active substances, vitamins and amino acids. Herbs give the product a special medico-biological value and provide high efficiency with minimal standards input. Prostor complex synbiotic preparation. The probiotic component of the Space ensures the biosecurity of the body, prevent the development of dysbacteriosis and stimulation of metabolic and immune processes. Provides increase in digestibility of forages, is the most important component of the effectiveness of feed additives. Prebiotic components in addition to exceptional nutritional values, provide a variety of adsorption centers, promote the growth of normal microflora, normalize motor skills, adsorbs toxins. A special enzyme complex that improves the nutrient absorption, the biotransformation of mycotoxins by converting them into inactive forms. Herb has immune modulating properties by increasing the natural protective forces of an organism, inhibits the growth and reproduction of Streptococcus, Staphylococcus, Escherichia coli, has a powerful detoxifying, hepatoprotector, antioxidant, is indispensable in the restoration of microflora of the gastrointestinal tract. Space - Stimulates the digestion of fiber, proteins, polysaccharides, neutralization of toxins, inhibition of pathogenic microorganisms by providing improved metabolism, motor and secretory functions of the digestive system; - Stimulates the immune system, provides greater security ; - Improves feed conversion; - Provides an increase in animal productivity by 3.2-18%; The effectiveness of Spaciousness in 3-8 times higher than the cost of its application. The norm of the input — 0.5-1 kg/ton of feed.
