The experiment studied the use of an herbal component in feeding of young geese, consisting of hay meal and alfalfa juices coagulate. The replacement of 50 % of complete feed by the studied feeding stuff reduced the protein content in the diet by 9.9-14.9 % and increased the content of crude fiber 1.76-2.01 times. Gross weight gain in the experimental group decreased by 3.9 %, with an increase in feed cost by 17.1 %. However, carcasses of geese in experimental group increased absolute weight of muscles of the breast and legs by 28.6%, and the relative – 5.6 % (Р˃0.05). Using of herbal ingredients tended to increase the yield of dressed carcass by 4.8 %, while the share of internal fat and skin with subcutaneous fat was decreased. There were no differences in the chemical composition of poultry muscle tissue in the groups. Using of herbal ingredients decreased the cost of 1 kg of feed by 0.7 rubles, but the cost price of weight gain increased by 5.0 %. It was concluded that it is necessary to carry out additional studies involving the feeding of poultry with the identical by nutritional value compound feed with the additive under study or without it
