Sorghum is an important source of grain and fodder, forage and biomass throughout the world. In the United States, grain sorghum is the prominent crop; however, non-grain sorghum plays an important role as a feedstock globally. This chapter reviews the different types of sorghum and their uses. We begin by considering the types of sorghum used for forage and biomass, and then offer a detailed discussion of the use of forage sorghum as feed for ruminant animals. We review the advantages of using sorghum as a dedicated energy crop, and finally consider the composition and uses of sweet sorghum cultivars.
