Abstract

The present work was carried out at Instituto de Zootecnia located in Nova Odessa county, São Paulo State, Brazil. The main objective was to evaluate some characteristics related to B. decumbens and B. brizantha cv. Marandu such as: dry matter production, crude protein, stem and leaf ratio and mineral composition. Cuttings were done in three frequencies (42, 56 and 84 days). The experiment was set in a complete randomized block design replicated four times. Dry matter percentage and yield did not show significant differences (P> 0.05) between the two grasses. There were differences (P < 0,05) between the two grasses for CP yield and percentage only in the 84 day frequency. Leaf percentage was superior for Marandu. Among the minerals, only P and Cu contents showed differences between the two grasses. Dry matter yields and percentages increased with plant age, while crude protein, phosphorus and copper contents and leaf percentage decreased in both grasses.
