Abstract

The present work was carried out at Faculdade de Ciéncias Agrárias e Veterinária de Jaboticabal. SP, Brazil, with the aim to study the effect of nitrogen fertilization (100kg N/ha/year) or legumes (Neonotonia wightii Willd. and Centrosema pubescens Benth.) and two stocking rat (1.5 and 2.0 heads/ha) on Guinea grass (Panicum maximum Jacq.) pastures composition. Available forage. chemical and botanical composition of pastures were determined. Animals used were crossbred steers of 200-250kg live weight and 9€”12 months o!d. Vegetation samples taked at intervals of 56 days showed higher available dry matter in nitrogen fertilizer pasture. However in dry season this higher production showed a low quality forage with respectively 2.74% and 81.75% for crude protein and ceil wail constituents. When the stocking rate increased legumes increased in the grass/legumes pastures and resulted in higher crude protein percentage in grass.
