FIELD: biotechnology and agriculture, in particular probiotic-containing compound feed for domestic animals, birds and fish.
SUBSTANCE: claimed additive is prepared by mixing of subtilis B-2250 and/or Bacillus licheniformis B-2252 biomass and carrier-sorbent and moisture capacitive filler as auxiliary substances. As carrier-sorbent hydrophilic and hydrophobic substances are used, and as moisture capacitive filler cation exchanging resins are used in predetermined ratio of dry mass. Probiotic additive in dry microcapsulated form is obtained by capillary sorptive drying of component mixture up to finished product humidity of 8-25 %.
EFFECT: probiotic additive with stable properties capable to improve feed conversion, to increase weight increment and to reduce animal mortality.
