The objective of the study is to determine the effect of the probiotic supplement BIO-SUBLICH on opti-mizing broiler feeding to improve their performance. The experiment was conducted at the production and technological complex of the Belgorod State Agricultural University named after V.Ya. Gorin. The floor-based poultry house is equipped with all modern equipment. Ten postgraduate students have been trained there over the past period, and five candidate dissertations have been defended to date. Four groups of birds were formed for the experiment, each consisting of 35 individuals. The control group received the basic diet without the probiotic supplement BIO-SUBLICH. The first experimental group received the basic diet with BIO-SUBLICH added at a rate of 0.17 %, the second group received 0.1 %, and the third group received 1.17 % of the total feed. Complete feed was supplied to the production and technological com-plex by the Plempticereproduktor Majskij feed mill (manufactured by Belgrankorm). During the experiment, broiler chickens in the experimental groups that used the new probiotic feed additive demonstrated positive dynamics in terms of livestock survival rates from 94.2 to 100 %, and live weight gain: by 2.86 % (1st experimental group), by 1.23 % (2nd experimental group), and by 0.36 % (3rd experimental group) compared to the control group (without the inclusion of BIO-SUBLICH in the diet). By 39 days of age, the average daily gain of broiler chickens in the first experimental group exceeded that of chickens in the con-trol group by 2.89 %, and feed costs were 3.4 % lower than in the control group, indicating improved eco-nomic performance in poultry production with the use of the BIO-SUBLICH probiotic feed supplement.
