This study was aimed to evaluate the quality indices of green biomass and hay of local ecotype of smooth brome (Bromus inermis Leyss.) and tall fescue (Festuca arundinacea Schreb.) cultivated at the “Alexandru Ciubotaru” National Botanical Garden (Institute) of Moldova State University. The biochemical composition of the green biomass varied between grass species: 12.4-13.1% crude protein (CP), 33.6-34.7% crude fibre (CF), 62.9-66.6% neutral detergent fibre (NDF), 36.9-37.8% acid detergent fibre (ADF), 2.8-3.6% acid detergent lignin (ADL), and 11.7-13.5% total soluble sugars (TSS). The forage quality of the green biomass included 594-602 g/kg dry matter digestibility (DMD), 553-563g/kg total digestible nutrients (TDN), relative feed value (RFV) of 87-90, and metabolizable energy (ME) of 9.67-9.76 MJ/kg. The hay had 10.3-12.4% CP, 36.0-36.9% CF, 65.0-69.1% NDF, and 6.2-9.4% TSS, with 528- 543g/kg TDN and ME of 9.45-9.60 MJ/kg. The biochemical methane potential of the substrates ranged from 331 to 366 L/kg volatile solids. These findings suggest that smooth brome and tall fescue are both suitable as high-quality forages for livestock and as promising substrates for biomethane production within renewable energy systems.
