The biological value of the bee drone brood homogenate is showed. In recent times, the bee drone brood homogenate has become widely used among the population. In particular, the nutritional value the drone brood homogenate is determined by a high content of carbohydrates, fats, proteins, organic acids, vitamins, mineral compounds and other important chemical agent for the body. In the fresh state, the drone brood homogenate is cream-like, a slightly viscous substance of light yellow color with a pleasant smell of baked bread and a specific sweet taste. It has a high content of fat, protein and high biological value of elements compounds. Production the drone brood homogenate includes: preparation of bee colonies, rearing of drone brood, selection of drone brood and their processing. The drone brood homogenate contains about 73 % of water, 13 % of protein (21 free amino acids), 1 % of fat (29 higher fatty acids), water- and fat-soluble vitamins, 131 mg/kg of carotene and also has an active acidity (pH) at level of 6.5 ± 0.29. Chemical analysis of different age drone brood shows that the vast majority of identified substances are contained in the homogenate of seven-day drone brood which are the most suitable for homogenization in order to obtain the highest quality product. It is known that drone brood has the same properties as royal jelly. Both of these products contain almost the same amount of protein and reducing sugars per unit of dry weight. It was studied the effectiveness of using substitutes protein feeds (defatted soya flour with soy peptides and pollen) in bee feeding during the harvesting honey. It was found that feeding bee colonies with soy peptides are increased the production of drone brood homogenate by 79.6 % in compared with using defatted soy flour.
