We investigated the biological peculiarities, chemical composition and nutritional value of the new perennial leguminous plants native to Caucasus: Astragalus galegiformis L. and Galega orientalis Lam. in Moldova’s conditions. Medicago sativa L. was used as control. Astragalus galegiformis and Galega orientalis achieves at the fi rst harvest, a productivity of 6.00 kg/m2 – 7.12 kg/m2 natural forage, second harvest – 1.68 - 2.04 kg/m2 natural forage. The natural forage of this species is characterized by a high content of raw protein, fat, nitrogen-free extractive substances and lower content of cellulose and minerals; contains a normal amount of protein which corresponds to the zootechnical standards, so, to a nutritional unit, correspond 127 - 147 grams of digestible protein and the highest content is found in the forage at the species Galega orientalis.
