Summary. The article presents the results of experimental studies on the effective use of Bacillus probiotic strains of animals with copper deficiency (for example, rats). Bacillus bacteria: Vetom 2 (B. subtilis 7048 strain and B. licheniformis 7038 strain) and Sporobacterin (B. subtilis 534 strain) were used as a probiotic agent. CuSO4 × 5H2O, which creates high element concentrations in nutrient substrate, acted as a regulatory factor for the excess concentration of copper ions in the experiment. The effectiveness of use of the obtained biologically active compounds was evaluated using atomic absorption spectrophotometry; skin, muscle and bone tissue were used as biological samples. The obtained data indicate a high potential for the use of probiotic drugs, which can stimulate the accumulation of copper in the body. So, in the samples of the experimental groups, the concentration of the test element exceeded the control group with a low copper content in the diet by 98.61%, 108.33%, and 81.94% at the end of the study. Based on the assessment of the level of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase in blood serum, there was no pathological effect of the tested compounds on hepatocytes, as evidenced by the dynamics of the studied parameters within the reference values ​​throughout the experiment.

Key words: animals, rats, feeding, copper, probiotic preparations, bacteria of Bacillus genus, mineral deficiency states.
