RESEARCHES CONCERNING THE EFFECTS OF SUPPLEMENTARY FEEDING OF BEES FAMILIES DURING AUTUMN, WINTER, SPRING

The purpose of the paper is to track the production of honey, its chemical analysis and determination of the economic efficiency of supplementary feeding of bee families during the fall, winter and spring. Chemical analysis of honey indicated in most cases according to its characteristics, supplementary trace evidence of industrial products and is noticeable only at the four experimental batches, where they found traces of industrial glucose. Although experimental batches recorded higher output compared to the control batch, however, due to expenses related to supplementation, only 3 groups, namely those who received Apiinvert, Melisol and glucose-fructose syrup recorded higher profits of 9%, respectively 31.6% compared to the control batch, retrieving other lower profits, the lowest value being noticeable in the experimental batch that was used as a semisolid food supplement, which had a deficit of 11.52% compared to the control batch.
