For vital processes bee family needs a considerable amount of food - honey and bee bread. In cases when the family
food supply is insufficient, the bees must be fed additionally. The purpose of research is to determine the influence of
the use of feed additives in bees feeding in queens growth. There was found that the optimum dose of the feed additive
Premix Bionorm P (Symbiotic complex) used to feed bee queen is 150 mg/l of sugar syrup. Feeding is performed daily
in the calculation of mixing 1 l per a bee family beginning with the introduction of the frame with transferred larvae till
the queen-cell capping for 5 days. It was found that the use of the feed additive (symbiotic complex) in the diet ensures
larvae adoption in growth of bee queens with 15,3-25,7%, compared with the control groups I and II , the queen-cell
mass increased with 60,0-110,0 mg or with 5,7-11%, the length – 0,1-0,2 cm or with 3,7-7,8% , the diameter – 0,03 cm
or with 2,5%, the body weight of unmated queens - with 1,94-6,62 mg or with 1,1-3,8% and mated queens with 20,86-
26,19 mg or with 9,1-11,7% .
