FIELD: agriculture; biotechnology.
SUBSTANCE: invention relates to the composition of a feed additive with probiotic activity and can be used in the preparation of feed for poultry. The feed additive consists of bacteria of the genus Bacillus and filler. The strains Bacillus subtilis VKPM 2335 and Bacillus licheniformis VKPM 2336 stored in the All-Russian Collection of Industrial Microorganisms (VKPM) were taken as spore-forming bacteria. Starch and sugar are used as fillers. Feeding a feed additive as part of mixed feed promotes the formation of the bird’s own intestinal microbiota, suppresses the development of pathogenic microorganisms, increases the productivity of birds and improves their physiological condition, and also reduces feed costs per unit of production.
EFFECT: invention will make it possible to expand the range of biologically active feed additives for functional purposes used in organizing the complete feeding of poultry.
