Studies on the effectiveness of the preparation were conducted in the field on four experimental groups, using different dosages of dihydroquercetin in each group. The maximum egg production of queens of bee colonies was observed in the second and third measurements in experimental group No. 3 when using dihydroquercetin at the rate of 15 mg/bee colony. The amount of commercial and gross honey obtained from bee colonies in experimental group No. 3 was recorded in the amount of 43.0 kg of gross honey and 20.1 kg of commercial honey. The difference with the control group, where dihydroquercetin was not used, was 41.5% and 17.4%, respectively. Thus, when introduced into the technology of keeping bee colonies as a stimulating feed additive in the amount of 15 mg per bee colony, the efficiency and vital activity of honey bees improves, which affects the increase in productivity of honey bees. %U https://easletters.com/article/productivity-of-honey-bees-apis-mellifera-fed-with-a-stimulating-feed-additive-rqa06ihghuesfv8
