This article presents the results of comprehensive studies to analyze the effect of a mixture of phytoecdysteroids extracted from the juice of Serratula coronata L. on the productivity and vitality of ducklings when grown for meat, and the optimal doses of its inclusion in the diet of the bird are revealed. The methodological basis of this study was the earlier works of domestic and foreign scientists on the topic under study. In the studies, a mixture of ecdysteroids extracted from the juice of the Serratula coronata L. was used according to the method developed by a team of scientists of the Ufa Federal Research Center of the Russian Academy of Sciences (Patent RU 2151598). The object of the study was the young ducks of the cross breed "Agidel 34" of the Beijing breed. It was established that the use of phytoecdysteroids in the diets of ducklings at a dose of 1.0 mg/l of drinking water allowed to increase the safety of the livestock by 4.0%, live weight by 4.5% (p < 0.01), average daily live weight gain by 3.0–3.5%, gutted carcass weight – 7.1%. At the same time, feed costs per unit of production decreased by 2.0%, and the profitability of duck meat production increased by 5.2%.
