Research of Impact of Direct Bioconversion of Secondary Grain and Fruit Raw Materials by Probiotic Microorganisms on Increasing the Protein Value of Feed Additives

Abstract

In this article, the prospects of using the germinated grain raw materials and methods of biotransformation (bioconversion) of secondary raw materials with subsequent microbial synthesis for increasing the biological and nutritional compound feed for birds is analyzed. A method for obtaining a protein feed additive for combined feed based on a biotransformed wheat germ product and apple marc powder used for the synthesis of probiotic bacterial microflora is described. The process was carried out on the analogy of the technology of preparation of liquid yeast at bakeries. The prototype of the nutrient medium was a leaven made from wheat flour of the second grade and wholemeal rye flour in a ratio of 7:3. Microbiological screening of products on the experimental and control nutrient substrate showed that the specific growth rate of the lactobacilli population in experimental substrate was almost 2 times higher, and the generation duration was 2 times less than in the control.
