With the annual increase of both cattle and small cattle, it is required to create and increase the fodder base of annual fodder crops with the content of the most high-protein, nutritious fodder. The purpose of the research was to compare and evaluate the dry matter nutritional value of multicomponent grass mixtures of annual cereals and legumes. The experience was laid down in “SPC GF named after A.I. Barayev” LLP, in the steppe zone of the Akmola region, Shortandinsky district, Nauchny village. The soils are southern carbonate chernozem, the granulometric composition is heavy loamy. Methods of research: field, laboratory, biochemical and comparative, statistical. The results of an analysis of the nutritional value of single-species and mixed crops of cereals and legumes are presented. Effective grass mixtures of Duman oats (70%) + Obskaya vetch 16 (20%) + KASIB peas (20%), Baizat oats (50%) + Obskaya vetch 16 (30%) + Oris peas (30%), Baizat oats (70%) + Obskaya vetch 16 (20%) + Oris peas (20%), Astana barley 2000 (50%) + Fodder millet 2014 (20%) + Status peas (30%) + Obskaya vetch 16 (30%), barley Astana 2000 (70%) + Fodder millet 2014 (30%) + Status peas (20%) + Obskaya vetch 16 (20%), Virgin barley 60 (50%) + Fodder millet 2008 (20%) + Oris peas (20%) + Obskaya vetch 16 (20%), Virgin barley 60 (70%) + Fodder millet 2008 (30%) + Oris peas (20%) + Obskaya vetch 16 (20%) in terms of digestible protein content per feed unit 110.7-123.6 g/feed. units, metabolic energy 9.41-10.24 MJ/kg, feed units in 1 kg of dry matter 0.717-0.849 kg/kg, which correspond to zootechnical standards.
