The use of flour from fly larvae in the feeding of farm animals is a new direction that is becoming increasingly widespread among the world’s leading producers. The technology of obtaining flour from fly larvae solves several critical problems of agricultural development: production of cheap and high-quality animal protein; replacement of imported components in animal feed; involvement of biological waste in secondary processing; reduction of environmental burden. The purpose of the work was to study the effectiveness of using innovative protein-lipid concentrate from fly larvae of the Lucilia Caesar population in feeding of young turkeys of the BIG-6 cross. In order to conduct the research 3 groups of young turkeys were formed with 20 heads in each (10 females and 10 males), which were housed separately. The control group has been received a general economic ration. The experimental groups have been fed protein-lipid concentrate: the 1st experimental group – 5,0 %, the 2nd experimental group – 7,5 % by weight of compound feed. The duration of fattening was 17 weeks. The positive effect of protein-lipid concentrate on the bioconversion of feed nutrients, the balance and use of nitrogen by the body of young turkeys, productivity and quality of meat was revealed. The physiological regularities of the effect of the studied feed on the intensity of metabolic processes in the body of females and males have been established. Optimal norms for the introduction of protein-lipid concentrate into the diets of young turkeys have been proposed. As a result of the experiment, the level of profitability from rearing experimental groups of young female turkeys increased by 1,49 and 2,21 abs.%, young male turkeys – 2,88 and 4,04 abs.% compared to the control groups.
