Conteúdo: | Grazing  trials were conducted in central Brazil to measure the effects of pasture attributes on beef production. In the first grazing trial, located in the state of Minas Gerais, the area was cleared from the original cerrado vegetation and planted with a local cultivar of guineagrass Panicum maximum cv ´Guine' with N fertilizer (100 kg N/ha) or with a mixture of legumes (Macroptilium atropurpureum. Glycine wightii and Stylosanthes guianansis. The experimental animals used were Gir x Holstein steers, and the pastures were grazed under the adjusted stocking-rate method. A completely random design was used with three replications. The results showed that N fertilization of the grass of the grass pasture resulted in a stocking rate significantly higher than the grass-legume treatment. Animal performance was markedly affected by treatment and  seasonal conditions. Grass-legume and N-fertilized grass pasture produced gains up to 453 and 547 kg/ha/year, respectively. When each season was  considered separately, there was essentially no difference in the  daily gain per animal between the two treatments. Glycine wightii was the most persistent of the legumes in this experiment. Calcium, P and protein of the forage removed by the steers were not limiting the cattle growth in the fertilized pastures...
