One of the main branches of animal husbandry is poultry farming, which has moved to an intensified path of development. The decision of the State programme for the development of agriculture and regulation of markets of agricultural products, raw materials and food provides for an increase in agricultural production, including the maximum solution to the problem of providing the population with meat. Ways of agricultural development in the context of globalization of the country’s market economy are aimed at providing the population with highquality and safe food, thus expenses are minimal. Large-scale chemization of various industries, irrational use of drugs lead to a milfuction of the microbial regime of the digestive tract of poultry. Disturbed acid-base balance in the body of poultry leads to a decrease in its productivity and quality of poultry products. Preservation of high poultry productivity directly depends on the effect on the adaptive and protective properties of its organism, through the use of additives of various origins. A lot of products for ensuring balance in an organism of a bird have appeared in the market of additives. Among them, the most effective are additives based on plant raw materials and succinic acid. The use of such additives can effectively increase the productivity of poultry when using traditional feed in combination with them. Succinic acid, calcium succinic acid, calcium fumaric acid, biologically active feed additives “Extrafit” and “Vita-Force” were used as test preparations. The result of adding biologically active additives to the diet of birds of the experimental groups contributed to an increase in their meat productivity by an average of 7.3–21.1 %. The effectiveness of different drugs at different age periods was not taken into account, the content of feed additives in the diets of broiler chickens did not have a negative effect on the general condition and well-being, positively influenced the intensity of their growth.
