ABSTRACT. In recent decades, metal nanoparticles have been studied and attempts have been made to use them in various fields of human activity. In the field of microbiology, such agents are often used as biocidal factors that contribute to the elimination of unwanted microflora. This work is devoted to assessing the effect of feed additives based on iron and copper nanoparticles with the addition of oak bark or probiotic preparations on the change in the sensitivity of the intestinal microflora of broilers to antibiotics. It has been shown that metal nanoparticles can lead to an increase in the number of antibiotic-resistant forms of bacteria, which potentially creates a genetic reserve that can be further used by unfavorable microflora.

KEYWORDS: nanoparticles, antibiotics, microflora, feed additive.
