Evaluation of sampling methods for quality evaluation of tropical forages under rotational stocking

Chemical composition and IVDMD of elephantgrass (Pennisetum purpureum, Schum. cv. Napier) and mombaçagrass (Panicum maximum, cv. Mombaça) were evaluated using samples of esophageal extrusa and hand-plucked samples. Greater DM, CP, and non-protein N concentrations were observed in the elephantgrass. Chemical composition of mombaçagrass, mainly DM and N concentration, varied with grazing day. Potentially degradable carbohydrate fraction differed between sampling techniques. No differences were observed regarding the kinetics of carbohydrates degradation for both grasses.
