Chemical Composition and Androgenic Effect of Bee Drone Larvae (Apilarnil) for Goat Male Kids

Abstract

Present study aimed to establish the stimulatory effects of bee drone larvae (BDL) on the androgenic effects and growth performance of goat male kids (GMK). The effects of BDL on growth and testosterone hormone levels were investigated in Saanen male kids. A total of 26 Saanen male kids (13 heads control, 13 heads treatment groups) were used for determining the effects of BDL 60 days after the weaning period. BDL was obtained from "good beekeeping practices" hives. Hormone levels, growth trials, testes characteristics, and body measurements were determined every 14 days on the days 75, 90, 105, 120, and 135 of the trial. The increasing level of testosterone hormone in the treatment group on 135 days strengthened the hypothesis that the BDL could have greater effects in the case of more application that is expensive and considering the time of maturity of Saanen GMK. The lipid composition of BDL was identified by GC/MS. Oleic acid (64.75 %) and palmitic acid (26.08 %) were the dominant lipid compounds of BDL. Additionally, the phenolic/organic acid profile investigated by HPLC-DAD revealed that trans-aconitic acid (11.20 +/- 0.32 mu g/g) and fumaric acid (5.03 +/- 0.41 mu g/g) were found as major compounds in BDL.
