LISTA, Fábio Nunes et al. Evaluation of sampling methods for quality evaluation of tropical forages under rotational stocking. R. Bras. Zootec. [online]. 2007, vol.36, n.5, pp. 1413-1418. ISSN 1806-9290. http://dx.doi.org/10.1590/S1516-35982007000600026.
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.
