Resumo
The objective of this study was to evaluate the effect of the addition of amino acids and
vitamins in the sucrose syrup used for Apis mellifera supplementation, in terms of its
productive and physiological aspects, as well as its economic viability. Two experiments were
carried out, the first in the apiary school of the EVZ / UFG and the second in a controlled
environment in the ICB/ UFG morphology laboratory in Goiania. The supplements tested in
the two experiments were: 50% sucrose syrup; sucrose syrup 50% + 0.5% of the commercial
amino acid / vitamin supplement (Promoter L®); sucrose syrup 50% + 0.5% amino acids in
proportion to the requirements of A. mellifera and sucrose syrup 50% + 0.5% amino acids are
in the proportion of the o royal jelly. The second experiment had a control treatment: mixture
of 66% honey and 34% pollen. In the first experiment, 16 hives were supplemented from
april to july, with four treatments and four replications. A completely randomized design was
used. The analyzed variables in the experiment were: capped brood area and honey
production. Difference between the treatments was observed for both variables, with best
results for sucrose syrup 50% + 0.5% of Promotor L® and sucrose syrup 50% + 0.5% of
amino acids in proportion of its requirements for A. mellifera. The cost / benefit ratio indicate
economic advantage for sucrose syrup 50% + 0.5% of amino acids in proportion of its
requirements for A. mellifera. In the second experiment were used 500 newly emerged bee
placed in experimental cages and distributed in randomized block design, in BOD greenhouse,
with five treatments and four repetitions of 25 bees confined for seven days. The analyzed
variables in the experiment were: food consumption; dry weight, survival rate, development
of hypopharyngeal gland, lipids and protein deposition in body and crude protein of
hemolymph. It was observed higher consumption of diets from the sucrose-based syrup
treatments when compared to the treatment with honey and pollen. Body deposition of lipids
was higher for treatment with honey and pollen. The survival rate were higher in treatment
with honey and pollen and treatment containing sucrose with amino acids in the proportions
of its requirements for A. mellifera. The development of hypopharyngeal glands differed
between the treatments, with best results for the treatment containing honey and pollen and
for the treatment with sucrose syrup with amino acids in the proportions of its requirements
for A. mellifera. The treatment containing only sucrose and the treatment containing sucrose
syrup with amino acids in the proportions of the royal jelly show the worst results. The dry
weight and deposition of proteins, where best for the treatment with honey and pollen, and
worst results for the treatment containing only sucrose syrup. Considering the results
obtained in the two experiments, it is recommended to use 50% sucrose supplement with
0.5% essential amino acids in the proportions of A. mellifera requirements in the off-seaso
