The objective was to evaluate the nutritive value of plants and silage of seven genotypes of sorghum (Podium, Formoso, BRS-610, IPA-1011, IPA-467, SF-15 and SS-318). A RBD with three replications was used to evaluate nutritive value of the plants cultivated in the municipalities of Barreiras and Muquem do Sao Francisco/BA, Brazil, while a CRD with three replications was used to evaluate the nutritive value of the silages from the plants cultivated in Barreiras. Chemical composition of forage and silage varied according to the genotype. However, the most remarkable effects were on CP, NDF, ADF and IVDMD. The best sorghum genotypes in terms of nutritive value were Podium, IPA-1011 e BRS-610.
