Introduction. The main task of beekeeping is to increase the number and productivity of bee families. In view of this, an important stage in the cultivation of honey bees is to stimulate the reproduction of bee families during their development. It has already been proven that natural food for bees (nectar, honey, pollen, bee milk) provides a sufficient amount of minerals and vitamins. Despite this, it is very often in certain periods of the development of bee families that their feeding is carried out, containing stimulants. In beekeeping practice, as a stimulant for feeding bees, a number of mineral salts and vitamins with proven positive effects on the body of bee families are used.

The goal of the work. The aim of the study was to increase the number and productivity of bee families by stimulating the drug "Kobacin" for the growth and reproduction of bee families during their evolution.

Materials and methods of research. Experimental studies of the feed supplement "Kobatcin" were conducted in the conditions of the Sumy NAU in the laboratory of beekeeping. The bee families that were included in the experiment were selected after a thorough spring survey during which indicators of family development were identified: strength, amount of honey and pollen in beer nests, number of sealed beet families. The bee families were housed in 10-frame hives. A 5-time dressing was performed at intervals of 5 days from the breeding of working bees. Indicators characterizing the development of bee families were determined by a measuring frame (5x5 cm squares) for 12 days to cover the total number of eggs deposited by the uterus during feeding.

Research results and their discussion. Analysis of the results of preparation for hibernation shows that the effect of the stimulant "Kobatcin" is preserved and the bee families, which were fed to them at the beginning of the season, enter into an inactive period of their life with more bees. Most of the sealed breeding in these families (calculated during the preparation for wintering – 30.08) suggests that in bee families, bees are young or as young as their physiological state. A greater number of best bees in bee nests prepared for wintering guarantees better wintering. Consequently, the use of the feed supplement "Kobatcin" in bee families in the spring retains its positive effect on the indicators characterizing families and at the end of the bee season. The amount of honey received from the bee families included in the experiment.

Conclusions and perspectives of further research: 1. It has been proved that the use of the feed supplement "Kobatcin" in a dose of 2.5 g / 500 ml of sugar solution 5 times with an interval of 5 days positively affects the characteristics that characterize the development of bee families (strength, number of sealed grasses) and their medical productivity. Positive influence is observed not only during feeding, but also in subsequent periods of development of families. 2. During the period of fertilization the number of rabbits in bee families receiving Kobacid increased significantly by 76.0% (71.2% in the group receiving only a sugar solution without this agent). The live weight of the bee stomachs in the families stimulated by "Kobacin" is 2.23% higher in comparison with the control group. 3. It was found that at the end of the bee-season, the bee families that were fed in May of the month "Kobatcin" have significantly higher values of strength, number of sealed brood and live bees compared to those who received pure sugar solution. Breeding in the control group was smaller by 24.58% compared with the experimental group. 4. Bee families who received "Kobatsin" during their wintering preparations had more bees than those fed with sugar only. The total amount of honey obtained from the families, which was fed at the beginning of the bee season "Kobatcin", is 21.63% higher than the experimental group. From the bee families of the experimental group received 36.89% more honey than the control group.
