Efficiency of use of compound feeds containing enriching feed concentrate of probiotic action

Ready-made compound feeds to ensure their effectiveness when used in animal fattening, as a rule, consist of different types of raw materials and are balanced by the content of nutrients in accordance with the physiological and age characteristics of animals and poultry. A large number of scientific studies have proved that the imbalance of diets on the most important indicators, in particular on protein and total energy value, reduces the genetic potential of animals and leads to overspending of feed. Due to the decline in recent years in the volume, range, quality and price increases for high-protein raw materials, the feed industry has experienced problems in the production of full-fledged, balanced in nutrients, and especially in protein, feed, which caused a reduction in their production and as a result, a decrease in the number of livestock.This study presents the results of zootechnical research aimed at improving the efficiency of using compound feeds enriched with probiotic feed concentrate in order to implement technologies for two-stage production of compound feeds based on feed concentrating concentrate from secondary raw materials using waste from grain processing and fat-and-oil production. Data confirming that when feeding animals with compound feed with the introduction of feed enrichment concentrate of probiotic action in comparison with the control, there is a slight increase in the coefficients of digestibility of nutrients in diets. For the most part, this applies to raw protein, raw fiber and raw fat, so the digestibility coefficients increased by 1.9; 1.2 and 1.1 %, respectively, while the digestibility without nitrogenous substances did not change significantly.
