The experiment was conducted at UNESP/FCAV, Jaboticabal, SP, with the objective of evaluating the influence of the rest period and height of the residue post-grazing on the dry matter mass, morphologic composition and on the chemical composition of the Tanzania-grass pre-grazing condition, under rotational grazing. The treatments consisted of the combination of two rest periods (25 and 35 days) and two residue height post-grazing (30 and 50 cm), as a complete randomized design in factorial arrangement 2 x 2, with three replications, with the grazing cycles considered as sub plots. The herbage mass of stem, leaves, dead material and the leaf: stem ratio were significantly influenced (P<0.05) by the grazing cycles. The percentage of CP in the leaf and stem and the NDF in the stem, leaf and whole plant were influenced positively (P<0.05) by the grazing cycles. It was observed that the short rest periods associated with the smallest residue height post-grazing presented the best results in terms of herbage mass and chemical characteristics of the herbage.
