Although sunflowers are commonly grown for seed production, they can also be used as a forage source for livestock. About one-third is the dry matter of the sunflower plant, so large amounts of potential forage are not used when grown for seed only. Stressed or low-yielding sunflowers can be profitable if used as a forage source for livestock. As a suitable alternative in drought conditions, sunflower forage is usually fed as silage and can be a valuable option.
