Description
Beef production in Brazil is based on the high dry-matter production of tropical grasses, but yields are not always satisfactory. Nitrogen fertilization results in linear increases of drymatter production (Gomide et al., 1984) and also in the liveweight-gain (LWG) of the animals (Addison et al., 1985). However, due to the high cost of fertilizers, the utilization of grass pastures associated to herbaceous or shrub legumes may be an economic way to increase animal production. The aim of this work was to study the availability of dry-matter and the L WG of steers in Guineagrass (Panicum maximum Jacq.) pastures fertilized with N or associated with perennial soybean (Neonotonia wightii Lackey) or pigeon pea (Cajanus cajan L. Mill. sp).
