The aim of the research was to study the effect of feed additive on the biological value of broiler chickens’ white meat protein under pre-slaughter stress conditions. The experiment was carried out on Arbor Acres broiler chickens in the conditions of an industrial poultry farm with floor housing technology. The main diet of poultry in the I experimental group was introduced with feed additive at a 1269 g/t feed dose, II - at a dose of 1693 g/t. The control group poultry received only the main diet. As a result, the white meat of broiler chickens of experimental groups contained 1.5-6.8% more essential amino acids, substituted by 1.3-5.5% compared to control. In the amino acid composition of the broiler chickens’ meat of the experimental group I, the most pronounced changes in the content of essential and dispensable amino acids were revealed; their level was above the control by an average of 3.7 and 2.9% respectively. White meat proteins of broiler chickens of the I experimental group were more biologically valuable; their amino acid score was above control by an average of 4.5%.
