Royal jelly production in Africanized honeybee colonies considering different protein supplements and the influence of environmental factors - DOI: 10.4025/actascianimsci.v32i1.6836

Abstract

This research was carried out to evaluate the effect of proteic supplement on royal jelly production in honeybee colonies and its correlation with environmental variables. The treatments were: colonies that had received a diet formulated with 35% crude protein, colonies that had received a commercial supplement with 35% crude protein, and colonies that did not receive protein diet. There was no difference (p > 0.05) among the treatments for parameters of production. The average for each variable was: amount accepted larvae, 8.56 ± 6.76; acceptance percentage, 29.20 ± 22.03%; amount of royal jelly produced per colony, 1.83 ± 0.82 g; and amount of royal jelly produced per cup, 213.58 ± 108.36 mg. Rainfall did not affect (p > 0.05) royal jelly production. The selected models point to a negative correlation among larvae accepted with the maximum temperature and low relative humidity. Larvae acceptance and royal jelly production per cup had a positive correlation with the maximum relative humidity and negative correlation with the minimum relative humidity. It can be concluded that the addition of proteic supplement (35%) did not increase royal jelly production of Africanized honeybee colonies, and its use for this purpose was unprofitable
