The article contains information on the results of an experiment on the introduction of an entomological feed additive into the diet of "Cobb-500" cross broilers. The milling of dry material of black soldier fly larvae (Hermetia illucens) was studied as a supplement. The biochemical profile of the investigated additive was preliminarily studied. The researches, used as a basis of the work, were aimed at studying the productivity indexes (average daily gain) and a number of biochemical blood indexes (total protein, albumin fraction, cholesterol of different fractions) of fattening poultry. A traditional diet based on mixed fodder was used as a control. The results of the research indicate the stimulation of anabolic processes in the poultry organism due to the use of the feed additive. An average daily gain increased by 11.5-13.2% over the control; the content of total blood protein increased by 6.8-9.2% due to the albumin fraction. The content of triglycerides in the blood increased more significantly (by 16.3-20.4% compared to the control). An increase in serum cholesterol content was also observed, and the growth of this index due to high-density lipoprotein fraction (HDL) should be regarded as a positive moment. The fact of excessive accumulation of abdominal fat in the experimental group (by 8.0-11.5% relatively to the control) should be regarded as negative against the background of stable weight gain. In this regard, it is promising to conduct similar studies with a supplement that has undergone entomological fat extraction.
