Abstract

The objective of this study was to evaluate dry matter production and animal performance in pastures of Coastcross + Arachis pintoi; Coastcross + Arachis pintoi with 100 kg ha-1 of N; Coastcross + Arachis pintoi with 200 kg ha-1 of N and Coastcross with 200 kg ha-1 of N, during winter, spring, summer and autumn. The experimental design was complete randomized blocks with split-plot parcels, with two repetitions. The study evaluated the accumulation of forage mass and dairy accumulation of forage mass, average daily gain (ADG), live weight gain and stocking rate. The used of Coastcross + 200 kg ha-1 of N and the best climatic conditions in the spring and summer, favored the accumulation of forage mass (26,764 kg ha-1 of DM) and daily accumulation of forage mass (82 kg ha-1 day-1 of DM). The use of the association between Arachis pintoi + 200 kg ha-1 of N and Coastcross + 200 kg ha-1 of N, produces best animal performance, with ADG of 0.570 and 0.500 kg and stocking rate of 3,.1 and 3.26 AU ha-1, respectively. The use of pasture intercropping without association with doses of nitrogen (100 and 200 kg ha-1) did not favor (p > 0.05) the accumulation of forage mass and dairy accumulation of forage mass. The utlization of 200 kg ha-1 of N, with and without the legume, favored greater animal performance and stocking rate.
