Summary. The development of new views on the use of the same antibiotic drugs in medicine and in animal husbandry revealed the problem of antibiotic resistance. In this regard, the need to find alternative substances (feed additives) that can be effectively used as a growth-promoting agent, including those with an antibiotic effect, is steadily increasing. In recent years, researchers have proposed several alternative methods to improve the functions of the microflora of the rumen, the processes of digestion and fermentation, as well as to increase the bioavailability and use of nutrients through the inclusion in the diets of animal feed additives. The review is aimed at studying the effect of the addition of rations of ruminants to probiotics or plant extracts and their metabolites on the productivity of animals. In addition, in the past decade, the functions of these non-pathogenic and non-toxic living microorganisms (probiotics) and biologically active compounds of plants (plant extract) are being studied due to the ban in developed countries on non-therapeutic use of antibiotics as growth promoters combined with critical consumer preference for quality and safe animal products. It is reported that these alternative supplements have a beneficial effect on both animal health and productivity, which affects stabilization of the rumen environment, inhibition of proliferation of pathogenic bacteria in the gastrointestinal tract, modulation of the immune response, increased degradation of fiber and fermentation, availability and use animal growth and production. Nevertheless, the need for long-term in vivo research is still more necessary to determine the synergistic effect of these two safe groups of substances.

Key words: cattle, probiotics, vegetable extracts, productivity, digestion, immunity.
