ABSTRACT

Animal liveweight gain can be augmented with the addition of a legume to a pasture system in the tropics, whether or not there is dry-season stress. However, where this occurs, the gain/unit area in pastures is highly dependent on its effect on the quality and quantity of plant material available to the grazing animal. When there is sufficient rainfall, the milk yield/unit area in nitrogen-fertilized grass pastures can be increased significantly over grass-legume pastures mainly due to higher carrying capacity.
