Recipes used for supplementary bee feeding and their consequences on colonies development are still the subject of numerous researches worldwide. This study examines the effects of using three types of energy syrups (2:1 sugar syrup, respectively corn syrup and syrup of enzymatic inverted sugar) on some morpho-productive indicators of bee families maintained in bee lofts (deprived from natural picking). The values of these parameters (the amount of wax produced in 9 weeks, the amount of food supplies at the beginning and end of the cold season) were statistically processed and then compared with those of some bee families maintained in the field (with access to natural picking). Regarding the bees deprived from natural picking, those fed with the 2:1 sugar syrup recorded the lowest values, while those fed with enzymatic inverted sugar syrup recorded the highest values of the monitored indicators. The values of these morpho-productive parameters were higher for the bee families in the field than those obtained from the bees from lofts, due to the quality of the food and the stress caused by the restriction of flight.
