The biochemical composition of the biomass of the oat cultivar 'Sorin' grown under the conditions of the Republic of Moldova and its possible uses

Abstract

We investigated the quality indices of the biomass from common oat Avena sativa, romanian cultivar 'Sorin' which was grown in the experimental plot of the ``Alexandru Ciubotaru'' National Botanical Garden (Institute), Chisinau, Republic of Moldova. The results revealed that the dry matter of whole oat plants contained 9.5% CP with forage value 598 g/kg DDM, RFV= 89, 11.84 MJ/kg DE, 9.72 MJ/kg ME and 5.37 MJ/kg NEl; prepared oat hay contained 10.5% CP, 574 g/kg DDM, 11.40 MJ/kg DE, 9.36 MJ/kg ME and 5.39 MJ/kg NEl. The oat haylage is characterized by pH = 3.77, 38.1 g/kg lactic acid, 5.9 g/kg acetic acid, 10.2% CP, 567-619 g/kg DDM, 11.28 MJ/kg DE, 9.26 MJ/kg ME and 5.29 MJ/kg NEl. The biochemical methane potential of the studied substrates from Avena sativa cv. 'Sorin' reaches 329-355 l/kg VS.
