Abstract:
Microbiological feed preparations are widely used in animal husbandry. These preparations include vitamins, amino acids, enzymes, lipid fractions, macro- and micro elements. They possess antioxidant, antibacterial, anti-stress, antiinflammatory properties. There are microbial preparations based on streptomycetes, which in the process of synthesis of antibacterial substances form a large number of metabolites diverse in chemical structure, distinguished by high biological activity and the ability to correct a number of impaired physiological functions.
