To increase the meat productivity of broiler chickens during fattening, they used a feed additive in the form of preparations based on humic compounds of sodium and potassium salts in various dosages and methods of giving. As a result of two prolonged experiments, the optimal scheme for the use of feed additives was experimentally worked out. The maximum gain in live weight by 9.7% compared with the control was induced by a feed additive based on a potassium humic preparation in the amount of 10% of the diet given with water and, accordingly, 9.1% with food. Sodium humic preparations were less effective than potassium, when fed in the amount of 10% of the diet with water, the gain increased by 6.7% compared with the control and, accordingly, 5.7% when given with food. When comparing the biochemical and hematological parameters of experimental and control groups of broiler chickens on the 5th day of life, that is, the starting values of their homeostasis, no statistically significant difference was found. Immediately before the experiment and the use of feed additives, the physiological potencies of all chickens were equal and their quantitative indicators were included in a single and homogeneous General population. During the period of using humic compounds that positively affected the metabolic and physiological processes of the macroorganism, as well as provided targeted correction and optimization for the intestinal microbiota, significantly different indicators of live weight gain of chickens were recorded between the experimental and control groups, with a significant difference in the actions of potassium and sodium salts of humic and methods of feeding. It turned out that potassium humic compounds are more effective than sodium, and feeding with water is better than with dry food. But the main thing is that the quantitative indicators of the physiological state of chickens of the experimental and control groups differed little from each other, and in some cases were the same. This indicates the physiology of the impact of feed additives and their safety for the macroorganism, and as a result, it provides a biochemically complete meat raw materials of high sanitary quality. That is, the use of feed additives biochemical and hematological parameters of blood in experimental and control groups consistently were within the physiological norm, which certainly proves that supplements are not excessively strong physiological stressor and provide Norelco functioning of all systems and organs of the organism, and the increased gain in live body weight of chickens of the experimental groups did not negatively affect the sanitary quality and biochemical composition of meat products. The intestinal microbiota in the experimental groups received a drug that showed prebiotic potencies and contributed to the normalization of the microflora composition, as evidenced by the isolation of signal microbionts - indicators of the sanitary well-being of a macroorganism such as Aerococcus viridans and Mycobacterium vaccae, as well as non-pathogenic variants of E. coli.
