Resumo: | To evaluate the grass B. brizantha cv. Marandu, under grazing, we use three sampling methods: total availability (TA), hand plucked (HP) and extrusa (EXT) in a completely randomized design with four replications. The hand plucked method was collected manually after observing the behavior of grazing animals. TA was determined by cutting at ground level, using a metallic square (0.25 m²) and EXT was collected by rumen evacuation. The values for dry matter (DM), neutral detergent fiber (NDF) and acid detergent fiber (ADF), were 27.20, 88.52 and 43.70% in the treatment and HP, and 25.53, 87.70 and 45.50% in TA. The extrusa had the lowest DM content (15.88%) and higher crude protein (CP) (15.22%), possibly due to the presence of saliva. The levels checked for extrusa NDF, ADF and in vitro digestibility of dry matter were 81.98, 36.90 and 79.10%, demonstrating the selectivity of the animals. The high levels of FDA for TA reflect the composition of the forage with the high proportion of senescent material. The samples obtained by the total availability were not representative of the diet consumed by cattle. The different sampling methods influence the chemical composition of B. Brizantha cv. Marandu. |
