It is necessary for the societies to reach their maximum strength at the beginning of the main pasture, and not for it to serve them for further development. The beekeeper himself plays a crucial role in the accelerated spring development of bee colonies. The aim of this study was to determine the effect of different ways of spring feeding on the strength of bee colonies and the food supply in them. The experiment was performed with companies that were in Db (Dadant-Blatt) and Lr (Langstroth-Ruth) hives. Four groups of companies were tested, and there were five companies in each group. The first group was supplemented with sugar syrup, enriched with vitamin-mineral complex - Foprsapine (10 drops per liter of syrup). The second group of societies was fed with honey dissolved in water (ratio of honey and water 1:1). The third group of the companies was fed with sugar dough (energy cake without additives). The fourth group of companies was supplemented with sugar syrup (the ratio of water and sugar was 1:1). At the beginning of the experiment, the societies in Lr hives had an average of 4.5 frames with bees, and 2.5 frames with a brood. In the Db hives, the societies occupied five frames with bees, and had 2.7 frames with a brood. At the end of the experiment Lr societies had 8.7 frames with bees, and 4.5 frames with brood, while Db societies had nine frames with bees, and 4.7 frames with brood. The experiment was performed at the apiary of the Institute for Forage Crops in Kruševac.enCC0 1.0 Universalhttp://creativecommons.org/publicdomain/zero/1.0/honey beespring developmentstimulating feedingDb and Lr hiveconferenceObject
