Abstract: We studied the biochemical composition and nutritive value of the green mass and prepared hay from local ecotipe of common knotgrass Polygonum aviculare
grown in monoculture on the experimental plot of the National Botanical Garden (Institute) “Alexandru Ciubotaru”, Chisinau, R. Moldova. Results revealed that dry matter of whole plant contained 173 g/kg CP, 293 g/kg CF, 84g/kg ash, 327g/kg ADF, 509 g/kg NDF, 55 g/kg ADL, 272g/kg Cel, 182 g/kg HC, 77 g/kg TSS, with nutritive and energy value 59.2% DMD, 51.7% ODM, RFV=116, 10.25 MJ/kg ME and 6.27MJ/kg NEl. The biochemical composition, nutritive and energy value of prepared hay from common knotgrass: 163 g/kg CP, 314 g/kg CF, 93 g/kg ash, 335 g/kg ADF, 491g/kg NDF, 52 g/kg ADL, 283g/kg Cel, 156 g/kg HC, 76 g/kg TSS, RFV=119, 10.16 MJ/kg ME and 6.18-6.54 MJ/kg NEl.
Keywords: biochemical composition, green mass, hay, nutritive value, Polygonum aviculare
