FIELD: agriculture.
SUBSTANCE: invention relates to microbiology and biologically active feed additives, in particular to a probiotic feed additive for agricultural animals and birds. Such additive includes spore-forming bacteria of Bacillus subtilis and Bacillus licheniformis B-020 strains (VKPM B-10995). As the bacteria of the Bacillus subtilis strain, it contains viable spores of spore-forming bacteria of the new Bacillus subtilis TB-26 strain (VKPM B-11954). Moreover, the spore forming bacteria of the Bacillus subtilis TB-26 strain (VKPM B-11954) and Bacillus licheniformis B-020 strain (VKPM B-10995) are taken in equal proportions with their total concentration of CFU colony forming units of at least 1⋅1012/ g.
EFFECT: use of the invention will increase the productivity and safety of livestock.
