Timothy grass, Phleum pratense, belongs to Poaceae family and is one of the most cultivated forage and pasture grasses in temperate regions. The aim of this study was to evaluate the forage quality of green mass and hay, silage and haylage prepared from timothy grass, Phleum pretense cv. 'Tirom’, created at the Research-Development Institute for Grasslands, Braşov, and cultivated in the experimental plot of the “Alexandru Ciubotaru” National Botanical Garden (Institute), Chisinau. It has been determined that the dry matter of harvested timothy grass green mass contained 10.4-12.4% CP, 28.9-35.1% CF, 7.5-8.5 % ash, 31.4-36.8 % ADF, 49.5-58.9 % NDF, 3.6-4.1 % ADL, 27.8-37.4 % Cel, 18.1-27.7 % HC, 170-27.3 g/kg TSS, 56.9-61.4% DMD, 54.9-60.0% OMD, RFV=95-121, 11.91-12.60 MJ/kg DE, 9.78-10.38 MJ/kg ME, 5.81-6.42 MJ/kg NEl. The biochemical composition and nutritive value of prepared hay was: 9.3-12.2 % CP, 30.1-36.7% CF, 7.1-9.6 % ash, 33.6-38.4 % ADF, 54.1-62.1 % NDF, 3.7-4.3 % ADL, 29.9-38.3 % Cel, 20.5-26.3 % HC, 165-181 g/kg TSS, 52.8-56.9% DMD, 50.0-53.5% OMD, RFV=88-108, 11.69-12.36 MJ/kg DE, 9.60-10.18/kg ME, 5.62-61.7 MJ/kg NEl. The ensiled timothy grass fodder (silage, haylage) had pleasant color and smell, pH = 4.07-5.61, 1.6-6.9 g/kg acetic acid, 12.9-27.7g/kg lactic acid and free of butyric acid, 9.0-9.5 % CP, 6.7-8.4 % ash, 40.8-41.6 % ADF, 68.1-71.6 % NDF, 2.9-3.8 % ADL, 37.0-38.3 % Cel, 27.3-30.0 % HC, 65-131 g/kg TSS, 51.7-56.0% DMD, 46.7-46.9% OMD, 11.24-11.36 MJ/kg DE, 9.23-9.33 MJ/kg ME, 5.25-5.34 MJ/kg NEl.
