The expediency of use of brewer’s dried grain in feeding of the young quails meat direction of productivity. It has no negative impact on digestibility and balance of Nitrogen in the body. The study was conducted in a scientific and experimental laboratory of feed additives of the National University of Life and Environmental Sciences of Ukraine on quail breed Pharaoh. Four groups of quails were formed with 100 heads each. Physiological experiments were carried out at 1621 and 3035 days old. For the experiments from the experimental groups, 4 heads were selected. As a result, it was proved that the digestibility of the feed changed with age and did not depend on the level of input of the brewer’s dried grain. Adding 24% of brewer’s dried grain in the mixed fodder contributed to the increase in organic matter digestibility by 1.5% and 1.7% in the first period and 22.6% in the second period of experience. In physiological experiments, the digestibility of the fiber was lower in the poultry, to which a brewer’s dried grain was added to the mixed fodder. The lowest digestibility of fiber was a bird with a level of 6% dry spent grain. Protein digestibility in poultry, which in the mixed fodder was introduced brewer’s dried grain, was higher than that which is not fed to a brewer’s dried grain.When reaching quails of 3035-day-old age, the level of Nitrogen consumption in comparison with the previous period increased by 1315%. The amount of Nitrogen consumed with food in the birds of the individual groups was different. The greatest amount of Nitrogen was retained in the body by quail, consuming mixed feeds containing 4% of dry beer pellets. They were controlling by 6.2% in this indicator. Compared with the control, less Nitrogen was contained in the body of the bird, which fed mixed fodder with 6% of dry beer pellets by 1.2%.
