METHOD OF THE FODDER ADDITIVE PREPARATION FROM BIRD DROPPINGS WITH THE USE OF BACILLUS SUBTILIS TNP-3-DEP AND BACILLUS SUBTILIS TNP-5-DEP BACTERIA STRAINS Russian patent published in 2019 - IPC A23K10/12 A23K10/26 

FIELD: agriculture; biotechnologies.

SUBSTANCE: invention relates to the feed additives production using the microorganisms. For the feed additive preparation, the laying hens droppings after preliminary feeding them with a probiotic consisting of an equal proportion of strains of the Bacillus subtilis TNP-3-DEP and Bacillus subtilis TNP-5-DEP bacteria in the 1% glucose solution with a concentration of 5×10⁸ CFU per 1 head is fermented with a probiotic consisting of Bacillus subtilis TNP-3-DEP and Bacillus subtilis TNP-5-DEP strains at the rate of 5×10⁸ CFU per 100 g of droppings. Resulting mass is subjected to the infrared drying at a temperature of 90°C for 30 min.

EFFECT: implementation of the invention allows to produce a feed additive with a high content of amino acids, nutrients and being microbiologically safe.
