摘要：

The objective of this research was to evaluate three grazing systems with Coastcross-1 (CC) + 100kg N ha(-1) year(-1) + common vetch; CC + 100kg N ha(-1) year(-1) + arrowleaf clover; and CC + 200kg N ha(-1) year(-1). Thirteen grazing cycles were performed during the experimental period (345 days). Lactating Holstein cows were used in the evaluation. The forage mass, botanical composition, leaf/stem ratio; daily accumulation rate, production and forage intake; grazing efficiency and stocking rate were evaluated. The average of forage production and stocking rate were 21.0, 20.3, 24.3t ha(-1) and 7.0, 6.5, 7.7 animal units ha(-1) day(-1) for the respective forage systems. Better results were found on Coastcross-1 mixed with common vetch and Coastcross-1 alone.
