Many research about use of energy syrups in bee nourishment show advantages and disadvantages of each ingredient. The aim of this study was to analyze the influence of three types of such energy supplements (sugar syrup 2:1, corn syrup and enzyme inverted sugar) on some parameters of bee families deprived by natural picking. These parameters (the number of bees, the amount of food supplies and the number of brood cells) were determined for 9 weeks, and the recorded values were processed and analyzed statistically for comparison with the results of other bee families maintained in the field. Values obtained from bees with access to natural picking were superior to those obtained from bees deprived on it. The colonies fed with enzymatic invert sugar syrup registered higher values of the monitored parameters and the lowest values were recorded in those fed with sugar syrup 2:1. Smaller values obtained from bees deprived by natural picking may also be caused by quality of food sources and the stress caused by the restriction of their flight.
