摘要：The distribution of feed containing probiotics is one of the most attractive trends in modern animal husbandry for consumers. The introduction of a live component makes the feed not only more effective, but also reduces the content of toxic components, making animal products more environmentally friendly. However, the introduction of viable cells of beneficial microorganisms into the feed significantly increases the requirements for the level of feed design, which in turn forces the development of new, unusual algorithms for such design for zootechnics. First of all, the development of feed additives with the inclusion of probiotic strains should be carried out only taking into account the specific application (type of animal of agricultural significance) and the extent to which the studied microorganisms and the substrate for microbial fermentation are suitable for this animal. The most important issue in this regard is the interaction of the living component with the inanimate one. At a minimum, substances that are part of probiotic feeds and feed additives should not inhibit the growth of target microorganisms. The ideal option is the ability to stimulate their growth or prebiotic activity.
