Biologically active substances of feed additives for dairy farming and modern assortment of products based on them

The article presents the results of the analysis of the register of feed additives developed for cows, as well as a brief description of the main groups of biologically active substances used in their production. The search for sources was carried out in bibliographic databases, in scientific electronic libraries with search engines: Web of Science (http://www.webofscience.com); Scopus (https:// www.scopus. com); eLIBRARY.RU (https://www.elibrary.ru); Viley Online Library (https:// onlinelibrary.wiley.com); Pubmed (https:// pubmed.ncbi.nlm.nih.gov). Scientific articles in English and Russian were accepted as sources of literature. The names of groups of substances of feed additives were used as keywords. The analysis showed that the Russian market of feed additives is represented mainly by the developments of foreign companies - out of 3696 items, 22.9% are domestic developments, 77.1% are foreign. Feed additives for dairy farming are represented by 1295 product names, which is 35% of the total number. According to the purpose of use, feed additives for cattle are classified into groups: for increasing productivity (energy feed additives, multicomponent feed additives, organic acids and their derivatives, aromatic and flavor feed additives, macro- and microelements and their complex compounds, vitamins and their derivatives, biologically active substances of plant origin containing flavonoids or flavoglycans, essential oils, herbal extracts, herbal extracts, enzymes, prebiotics, biologically active protein substances, amino acids, their salts and compounds), for the safety of young animals (vitamins and their derivatives, 1 energy feed additives, prebiotics, multicomponent feed additives, macro- and microelements and their complex compounds, amino acids, their salts and compounds, biologically active substances of plant origin containing flavonoids or flavoglycans, essential oils, herbal extracts, herbal extracts, organic acids and their derivatives). Most feed additives are designed to improve milk productivity and contain mixtures of fatty acids – 33%, microelements – 25%, vitamins – 21%, plant extracts and essential oils – 10%, microorganisms – 10%, amino acids – 9%, and a complex of organic acids – 8%.
