Soybean, Glycine max, is grown primarily for seed production and has a long history of being grown as a forage crop. The main objective of this research was to evaluate the quality of green mass, prepared hay and haylage from soybean Glycine max cv. 'CLAVERA’, cultivated in the experimental plot of the National Botanical Garden (Institute) “Alexandru Ciubotaru”, Chisinau, Republic of Moldova. The results revealed that the harvested soybean whole plants contained 26.5 % dry matter. The concentration of nutrients in the dry matter of green mass was: 178 g/kg CP, 286 g/kg CF, 94 g/kg ash, 310 g/kg ADF, 484 g/kg NDF, 49 g/kg ADL, 142 g/kg TSS, 261 g/kg Cel, 174 g/kg HC, with nutritive and energy value 68.6% DMD, 63.4% DOM, RFV=124, 12.73 MJ/kg DE, 10.48 MJ/kg ME and 6.46 MJ/kg NEl. The biochemical composition, nutritive and energy value of prepared hay: 173 g/kg CP, 303 g/kg CF, 105 g/kg ash, 331 g/kg ADF, 504 g/kg NDF, 53 g/kg ADL, 110 g/kg TSS, 278 g/kg Cel and 173 g/kg HC, 64.6% DMD, 57.8% DOM, RFV=116, 12.42 MJ/kg DE, 10.20 MJ/kg ME and 6.22 MJ/kg NEl. The haylage is characterized by pH = 4.69, 13.4 g/kg acetic acid, 69.3 g/kg lactic acid, 181 g/kg CP, 319 g/kg CF, 126 g/kg ash, 334 g/kg ADF, 510 g/kg NDF, 42 g/kg ADL, 71 g/kg TSS, 292 g/kg Cel, 176 g/kg HC, with nutritive and energy value 63.0% DMD, 55.8% DOM, RFV=115, 12.40 MJ/kg DE, 10.18 MJ/kg ME and 6.19 MJ/kg NEl. We consider that soybean forage may be used as multi-purpose feed for livestock.
