The objective of this work was to evaluate the agronomic performance of Xaraes palisadegrass [Brachiaria brizantha (A. Rich.) Stapf cv. Xaraes] in response to rotational grazing managements defined by either pre-graze canopy light interception (LI) or calendar days. Mean pre-graze sward height was 29.5 cm for the 95% LI pastures, 41.6 cm for 100% LI, and 34.2 cm for the 28-day schedule. Mean post-graze sward height was 14.6 cm across treatments, which corresponded to a mean 0.73 leaf area index, 42% LI and 65.2o foliage angle. At pre-graze, foliage angles were not affected by grazing management (mean = 41.6o). Sward height and LI were highly correlated across treatments. Grazing at 100% LI resulted in longer intervals between grazings and higher herbage accumulation than the other two treatments, although this higher accumulation corresponded mainly to large amounts of stem and dead material.
