Poultry farming in the Russian Federation is one of the key branches of animal husbandry, providing the population with dietary and high-calorie food products such as meat and eggs. In this regard, the production of the maximum amount of competitive high-quality products is possible only under conditions that take into account the biological characteristics of the poultry, its physiological state, the type of productivity and the infl uence of environmental factors on it. The main factor in increasing the productivity of poultry is a rational and balanced feeding system. In the feeding of poultry, the search for new alternative feed sources is promising in the fi eld of feeding. One of such non–traditional feed sources is the product of processing amaranth seeds into oil as amaranth cake. We carried out scientifi c and production experiments at the Research center for the safety and eff ectiveness of feed and additives at the Volgograd State Agrarian University on broiler chickens of the cross Ross 308 and laying hens of the cross Hisex Brown. The poultry of the control group, both in the fi rst and in the second experiments received compound feed with sunfl ower presscake, and in the diet of poultry of the 1st, 2nd and 3rd experimental groups 50, 75 and 100 % sunfl ower presscake was replaced with amaranth presscake. Replacing sunfl ower presscake with amaranth presscake in compound feed for broiler chickens allowed to increase the live weight by 2,15–5,26 %, increase the slaughter yield of carcasses by 0,15 -0,29 abs.% and reduce feed expenditures per unit of live weight gain by 2,08–4,98 %. The inclusion of amaranth presscake instead of sunfl ower presscake in the formula of compound feed for laying hens allowed to increase the number of laid eggs by 0,52–1,54 % and their weight by 0,50–1,45 %, while there was a decrease in the expenditures of feed for 10 pieces of eggs and 1 kg of egg mass by 0,75–1,50 % and 0,93–2,80 %. Thus, the replacement of sunfl ower presscake with amaranth presscake in compound feed for laying hens and broiler chickens had a positive infl uence on the productive parameters of poultry.
