The purpose of the research was a comparative testing, in bee feeding, of various nutritional supplements derived from the Spirulina platensis cianobacteries biomass cultivated in the presence of some organic coordinative compounds of the new generation, and the development, on its basis, of new nutritional supplements and feeding methods of bee families during the periods of poor harvesting in nature. The research was performed on five identical bee family batches, each batch composed of ten families, which received 100 ml of nutritional mixture of sugar syrup with water (1:1) per comb space populated with bees at the beginning of April, every other day, during two weeks. For the bee families from the experimental batches (II, III, IV, and V), the sugar syrup was enriched with different nutritional supplements obtained from the Spirulina platensis biomass extract, cultivated in the presence of some organic coordinative compounds. The nutritional supplements were administered in an amount of 20 mg of dry matter per liter of the mixture. The bee families from batch II got the bioactive supplement Apispir in the food, the bees from batch III received Apispir + Zn, those from batch IV Apispir + Cr, and the bees from batch V Apispir + Fe + Se. The results of the research demonstrate that feeding bees with a nutritional mixture of sugar syrup enriched with the bioactive supplements obtained from the Spirulina platensis biomass extract cultivated in the presence of some organic coordinative compounds in early spring during the poor harvesting in nature has contributed to a significant increase of the queens prolificacy, by 607 1,390 eggs/24 hours, or 32.674.4 % (td = 2.938.99; P 0.010.001) of the capped brood quantity, by 73167 hundred of cells or 32.674.6 % (td
