Panicum sort the grassy ones are classified in two categories how much its ambient adaptation and fotossinttica efficiency, tempering species (C3 plants) and tropical (C4 plants). Normally, the tempered forrageiras species present quality, definite better in terms of digestibilidade, consumption and text of protein (Moreira et al. 2006). The sort Panicum L. is one of the more important greaters and of the Poaceae family.
