However, systems including forestry in their arrangement, are naturally more complex, as trees exert a direct influence on the whole system’s productivity. Goal of this work was to evaluate forage production potential and nutritive value of Brachiaria cultivars under integrated crop-livestock (ICL) and integrated crop-livestockforestry (ICLF) systems, in their initial phase, just after grass establishment. Experimental design wasrandomized block with split-plots and two replications. Treatment on plots consisted of systems (ICL and ICLF), the subplot, the cultivars of Brachiaria sp. (BRS Ipyporã, BRS Paiaguás, BRS Piatã and Ruziziensis), the sub-subplot, post-cut residue height (15 and 20 cm), and, the sub-subsubplot, seasons of the year (autumn, winter, spring and summer). Results show that shading after one year after grass establishing under integrated systems does not affect forage production and leaf crude protein content of Brachiaria cultivars. BRS Piatã produces more biomass than the other cultivars, with good leaf crude protein content. For Brachiaria cultivars, residue height at 15 cm produces greater biomass than at 20 cm.  aCultivars  aForage production  aShade  aSilvopastoral systems  aBrachiaria  aForragem  aPolíticas Públicas  aVariedade1 aDELMONDES, T.
