Soy bean meal, 5. Pollen, 6. Sugar syrup. Actually, sugar syrup and pollen were used as control treatments. The results of statistical analysis of data showed significant difference in food consumption (P<0.05), where the highest to lowest food consumption of belonged to: fermented Gluten meal, Pollen, fermented Soy bean meal, Gluten meal, Soy bean meal and sugar respectively. Significant effect was seen on brood rearing (P<0.05), Fermentation gluten and soybean meal had the highest and lowest brood rearing between treatments respectively. No significant differences were seen in body protein and population size (P>0.05). The results of this experiment showed that fermenting protein sources has positive effects on health and increasing brood rearing in honeybee colonies.
