PROBIOTIC LACTOMICROCICOL USED IN GROWING AND FATTENING BROILER POULTRY

摘要

FIELD: biotechnology, microbiology, agriculture.;SUBSTANCE: the probiotic lactomicrocicol comprises microbial biomass of microorganisms of strain Lactobacillus amylovorus BT-24/88 (VKPM, B-6253) and Escherichia coli S-5/98 (VKPM, B-8564) taken in the ratio = 1:1 in the concentration of colony-forming units of each strain in the range (5 x 10⁸)-(5 x 10⁹) CFU in 1 ml of liquid or 1 g of dry preparation. Lactobacillar strain possesses the broad spectrum of antagonistic activity and multiple antibiotic-resistance and Escherichia coli produces microcin B-5/98 suppressing opportunistic and pathogenic microorganisms of genus Escherichia and Salmonella. Using the proposed probiotic in feeding broiler-chickens taken in the dose 0.2 g per 1 kg of dry fodder or 1 l of drinking water provides enhancing their safety, gain of living mass and the yield of production of the 1-st category.;EFFECT: valuable properties of probiotic.;1 tbl, 3 ex
