The aim of this study was to determine the green mass productivity, the biochemical composition and the fodder value of a perennial legume – bird’s-foot-trefoil, Lotus corniculatus cv. Doru, grown in an experimental field of the National Botanical Garden (Institute), Chişinău. In the third growing season, the bird’s-foot-trefoil was characterized by high growth rate and regenerative capacity after mowing, making it possible to mow it four times per season. The annual productivity was 44.50 t/ha green mass or 9.70 t/ha dry matter. It was determined that the quality of the green mass varied depending on the harvest time: crude protein 143.5-194.5 g/kg DM, crude fats 30.1-44.8 g/kg DM, crude cellulose 261.7-357.0 g/kg DM, nitrogen free extract 338.3-456.1 g/kg DM, sugars 37.5-61.0 g/kg, starch 18.1-37.8 g/kg, carotene 48.45-77.00 mg/kg, calcium 10.6-14.9 g/kg and phosphorus 2.2-3.3 g/kg. The biochemical and fodder value of the prepared haylages from first and second cuts were: pH 4.46-4.70, lactic acid 34.1-37.2 g/kg DM, acetic acid 5.7-9.4 g/kg DM, butyric acid 0.2 g/kg DM, organic matter 891.8-902.2 g/kg DM, crude protein 170.9-188.8 g/kg DM, crude fats 41.6-44.6 g/kg DM, crude cellulose 332.2-358.9 g/kg DM, nitrogen free extract 298.6-357.5 g/kg DM, sugars 0.87-1.86%, starch 0.91-1.76%, carotene 14.0-24.0 mg/kg, calcium 10.0-10.8 g/kg DM and phosphorus 2.7-3.1 g/kg DM. The prepared hay from first and second cuts contained 18.89-20.76% crude protein, 2.56-2.74% crude fats, 31.62-32.42 % crude cellulose, 33.86-36.33 % nitrogen free extracts, 10.49-11.01 % ash.
