FIELD: mixed feed production.
SUBSTANCE: thin layer of feed is sprayed with a probiotic preparation Bifidumbacterin containing a strain of Bifidobacterium bifidum with a titer of live bacteria of at least 1,107 CFU, previously dissolved in distilled water. A thin layer of feed is preliminarily sprayed with ultrafine particles of iron, 100±2 nm in size, obtained by high-temperature condensation, dispersed in distilled water for 30 minutes at a frequency of 35 kHz, in the amount of 30 mg/kg of feed, and the probiotic preparation Bifidumbacterin dissolved in distilled water, in the amount of 0.747 mg/kg of feed.
EFFECT: increase in the productivity of fish.
