Duskaev G.K., Drozdova E.A., Alyoshina E.S., Bezryadina A.S. ESTIMATION OF IMPACT ON THE INTESTINAL MICROFLOR OF BIRDS OF SUBSTANCES WITH ANTIBIOTIC, PROBIOTIC AND ANTI-QUORUM SENSING EFFECTSThe search for ways to increase the productivity of farm animals has always been one of the most important areas of research. Poultry farming was no exception. The study of new possibilities for using preparations of both synthetic and vegetable origin, consideration of their composition and properties, as well as investigation of the effects exerted by them on the intestinal microflora, will make it possible to avoid possible deplorable consequences for both poultry and human beings. Substances such as probiotic Lactobifadol, Biovit antibiotic and oak bark extract, in various volumes have both an overwhelming and stimulating effect on the intestinal microflora of the bird. Extract of the oak bark had a serious depressing effect on the intestinal biota of the bird. There was an obvious relationship between the increase in the volume of the extract and the degree of suppression of the intestinal microflora. The use of the probiotic Lactobifadol stimulated the quantitative composition of the intestinal microflora of the bird, however, when the probiotic was combined with the oak bark extract, the number of microorganisms in the sample was reduced. The use of antibiotic Biovit contributed to a serious inhibition of the intestinal microbiota of the bird. But when studying the joint action of the drug with the extract of the oak cortex, partial inactivation of the bactericidal effects occurred, as evidenced by higher values of the colony forming units (CFU), relative to the single use of the antibiotic.Key words: broiler chickens, probiotics, antibiotics, oak bark extract, Quorum Sensing system of bacterial cells.
