Produção e valor nutricional de gramíneas temperadas e leguminosa em consórcio

Abstract

In southern Brazil, temperate forage grasses are essential for feeding animals during the winter period, when the nutritional quality and availability of pasture decreases due to low temperatures. In this sense, diversifying species, as well as the use of consortia, can be na alternative aimed at more productive and efficient pastures. Thus, the treatments applied were TritAz - Triticale + Ryegrass; TritAzTv - Triticale + Ryegrass + Vesicular Clover; CentAz - Rye + Ryegrass and CentAzTv - Rye + Ryegrass + Vesicular Clover, in an experimental design in randomized blocks, with three replications and four consortia cultivated in plots with an área of 12m², totaling 12 experimental units. Tiller dynamics and density were evaluated in three cycles with an interval of 28 days. The botanical and structural separation samples were separated by species and subsequently into stem and leaf. Among the bromatological analyzes MS, MM, CP, FDN, DIVMS were evaluated. The treatments did not differ statistically for the dynamics and density evaluations nor for the production evaluations, but they did differ for the bromatological composition analyzes where the intercrops with triticale showed better nutritional value compared to those with rye, and the intercrops with vesicular clover showed a reduction in their NDF content.
