We conducted this study in order to determine the effects of intercropping Sorghum bicolor and Brachiaria brizantha under the nutritional value of silage and analysis of production parameters related to this consortium. After 60 days and the fermentation stage of the material already completed, the silos were opened. The treatments were: Brachiaria singles in planting, planting sorghum in singles, sorghum intercropped with grass in row and between rows of planting sorghum intercropped with grass planted between the rows, intercropped withsorghum grass in the row. We used a randomized complete block design with five replicates per treatment. The higher content of organic matter such as sorghum was unmarried, with no difference between the consortia and Brachiaria single. The consortium did not differ amongthemselves and had higher values than the single grain sorghum in the contents of mineral matter. The planting of sorghum intercropped with sorghum and grass in line with grass between the rows increased the lignin content. In vitro digestibility of dry matter was decreased by the mixed stands compared to sorghum silage single. The crude protein were higher in mixed stands and Brachiaria unmarried singles in sorghum silage. There was no difference between the variables dry matter, ether extract, neutral detergent fiber, acid detergent fiber, cellulose, hemicellulose, and total digestible nutrients. Already in production parameters of the consortium did not exert signi ficant influence on the heights of sorghum plants and grass. The stands were greater in mixed stands than in sorghum that being unmarried, sorghum grass with the line had the best result. The best production of greenBrachiaria was unmarried, and sorghum in line with grass and rows of sorghum with planting and grass between the lines were better than the single grain sorghum and sorghum with grass on the line. The production of green matter was influenced by the mixed stands, being better at planting of sorghum grass with the line and with canopy and grass between the lines but they did not differ from that increased production of Brachiaria was unmarried.
