Deferred pasture can be harvest by grazing or mechanically. The mechanized harvest increases the efficiency of fodder utilization. However, these technique increases the portion of stem and dead material of the feed relative to the total forage grazed, witch compromises the quality of the forage. The objective of this experiment was to evaluate the ability of shaded pastures of Piatã brachiaria grass (Brachiaria brizantha cv. Piatã) to maintain chemical composition of the whole plant and determine the potential benefits in relation to full light condition. The experiment was performed at Embrapa Agrossilvipastoril, Sinop, MT, Brazil (11º51'43'' S, 55º35'27'' W, 384 m) from February to June 2014. A crop-livestock-forest integration area was divided into two light regimes: Piatã cultivated in the absence of trees (full natural light; FL); and Piatã cultivated under shade produced by four triple rows of trees (Eucaliptus H13 clone, 650 trees ha-1) with pasture between the rows (S2). Treatments correspond to combinations between: light regimes (FL and S2), two beginnings of rest period (R1 ? February 26, R2 ? March 28) and two grazing dates (G1 ? May 16, G2 ? June 16). These were applied to experimental units (15 x 4 m plots) in a 2x2x2 factorial arrangement, with four replications. Total rainfall and duration of deferment corresponded to 223 mm and 79 days (R1G1), 257 mm and 110 days (R1G2), 126 mm and 49 days (R2G1) and 150 mm and 80 days (R2G2), respectively. At the beginning of rest period (R1 and R2), plots were mowed at 10 cm and at the end of the deferment period (G1 and G2) four samples harvested (0.25 m2). These samples were mixed and a whole plant portion was separated and analyzed by Near Infrared Reflectance Spectroscopy (NIRS). Statistical analysis was performed using PROC Mixed of SAS at a 5% probability level. Light regime S2 showed 40% of the light transmittance of FL (100%). Crude protein was higher for S2 than FL (97.4 and 71.7 g DM kg-1) and for G1 than G2 (95.5 and 73.6 g DM kg-1). Neutral detergent fiber was higher for FL, R1 and G2 (714, 714 and 716 g DM kg-1) relative to S2, R2 and G1 (705, 704 and 702 g DM kg-1, respectively). Acid detergent fiber was higher for R1 than R2 (395 and 384 g DM kg-1) and for G2 than G1 (399 and 380 g DM kg-1). The organic matter digestibility was higher for G1 than G2 (579 and 538 g DM kg-1). Dead material was 12% higher for G2 than G1 and it was the main reason that G2 presented the worst values of the chemical analysis. In conclusion, although the results were interfered by light regimes and rest dates, the main effects on whole plant chemical composition was caused by prolonging of the deferment period into unfavorable season for the development of the plant.
