Abstract

The aim of the work was to study the biological activity of extracts of promising fodder grasses Onobrýchis arenária, Galéga orientalis and Rhaponticum carthamoide. The extracts had antiradical, chelating and prooxidant activity and the ability to inhibit the formation of biofilms. The most noticeable biological activity was observed in Galéga orientális, a high-yielding crop rich in protein and fiber. Taking into account the ability of extracts to inhibit the formation of biofilms, it should be recognized that the use of the studied herbs is promising for reducing the colonization of the intestines of ruminants by pathogenic bacteria. Although the extracts showed no antimicrobial activity, they markedly modulated the bacterial response to antibiotics, affecting growth rate, respiration, and number of persisters. In most cases, there was a decrease in the effectiveness of antibiotics such as kanamycin, tetracycline and cefotaxime. The studies used extracts of fodder grasses grown in 2019-2020 on the experimental fields of the Perm Agriculture Research Institute Ural Branch RAS, located in the Lobanovo village, Perm District, Perm region.
