Review of studies on the use of synbiotic feed additives in compound feeds

Abstract

The article discusses feed additives with probiotic activity, the composition and methods of their preparation, an assessment of the situation of the use of synbiotic additives in compound feeds. Generalised literature data on the use of synbiotics in animal husbandry and aquaculture are presented, their advantages and disadvantages are revealed. A review of studies on the use of feed with probiotic activity in the diet of animals, birds and fish proves the high effectiveness of their use: there is an increase in survival, a decrease in feed conversion, an improvement in the microbiota and the general condition of the animal. Based on the review, a new substrate for growing bacterial strains based on a grain heap of wheat in the early stages of ripeness is proposed.
