The article presents the results of studies of the effect of the biologically active additive Vetom-1.1 on the quality of wintering and the spring development of bee colonies. The Vetom-1.1 additive is used to regulate the microbiocenosis of the gastrointestinal tract, increase the natural resistance of the body and increase the safety and productivity of agricultural, domestic animals and poultry. The object of the study was the bee families of a peasant farm. Bee colonies were divided by the method of pairs of analogues into control and experimental groups. Each group included six families with the current year’s queens. As part of an autumn feeding, the bee colonies of the experimental group were twice given sugar syrup (1:1) in the amount of 200 ml with the addition of five grams of Vetom-1.1 per family with an interval of five days. The results of the studies were taken into account for two years in the spring, after the flying rout. The quality of wintering was determined by the number of dead families, the presence of diarrhea on the walls and frames of the hive, the presence of brood, its quantity and quality and the presence of dead bees. Analysis of the results of the study has shown that the two-year feeding of the veterinary therapeutic and prophylactic drug Vetom-1.1 to bee families ensured one hundred percent safety of bees in the winter, the rapid growth of bee colonies in spring and summer. From six families at the beginning of the experiment, the group increased to 22 bee colonies that went into winter at the end of the second year of testing. At the same time, the productivity of bee colonies in comparison with the control in the first year was 20% higher, and in the second year the gap was 70%. In the first year in the control group, the proportion of dead bees was 33% with a characteristic feature of death from a viral disease
