Influence of bioutiluzation on quality and safety indicators of sunflower husk

Sunflower husk is formed during the production of sunflower oil and due to its poor digestibility by the body, cannot be widely used for animal feed. The authors studied the effect of microbiological fermentation during fermentation for 12 and 24 hours on the quality and safety indicators of sunflower husk. The results of laboratory studies have proven that 1) regardless of the time of microbiological fermentation, the mass fraction of moisture, crude fat, and crude fiber significantly decreased; the mass fraction of crude protein, crude ash, and starch content increased; the level of metabolic energy for all animal species and the content of soluble carbohydrates increased, but the difference was not significant; 2) the resulting fermented product meets the biological and chemical safety requirements for animal feed.
