Influence of integrated crop-livestock-forest on morphological composition and nutritional value of Marandu palisadegrass under continuous grazing

This study characterizes the changes in leaf mass, morphological composition and nutritional value of blades palisadegrass (Urochloa brizantha cv. Marandu) under continuous grazing first year implementation pasture after second eucalyptus planting an Integrated Crop-Livestock System Crop-Livestock-Forest, which were tested four seasons. The experimental design was random blocks, with three treatments: (ICL) Crop-Livestock-Forest two tree densities (ICLF-1L, 196 trees ha-1 ICLF-3L, 448 ha-1) replicates. Sixty castrated Nellore cattle initial weight 235.43 ± 25.46 kg mean age 16 2.81 months used during growing phase grazing. agronomic variables were: total dry mass forage, leaves, stem dead material; leaf: live: senescent material ratios; accumulation rate. relation did not obtain any difference between evaluated systems. Dry matter, crude protein, fiber fractions digestibility evaluated. forage (6775 ha-1), (2175 (3175 matter content (28.6%) greater ICL, whereas protein (11.3%) ICLFs. On other hand, rate change Thus, until grazing, systems have advantages, because production (accumulation rate) are similar to those plants full sun, besides showing higher value.
