Abstract
The objective of this study was to evaluate the chemical composition of the pasture Brachiaria Brizantha intercropped with peanut or fertilized with N and carcass characteristics of beef cattle. The pasture was managed under rotational grazing with stocking continues, with variable stocking, using 16 Nellore bulls. In the evaluation of dry matter production total green significance was observed between treatments and periods evaluated, and treatment consortium presented a higher average. The variable crude protein showed significance between treatments and periods. The NDT and FDN had no significant effect on the evaluation of the grass. Periods had lower ADG were the 4th and 6th periods. For the PB, FDN and NDT legume 3rd period showed the lowest averages. For variables GMD, NAD, GPC showed statistical significance for the interaction, and the 1st treatment period consortium submitted the highest averages. In the treatment of the largest fertilizer stocking rates were achieved in stations where chemical fertilization occurred. Statistical significance was observed for the variable conformation carcass classification. The consortium forage peanut cv. Belmonte may be using to replace fertilization with 120kg / N / ha, as it ensures even weight gain per animal, without changing the commercial carcass traits.
