GOES, R.H.T.B. et al. Method of sampling and chemical characterization of Marandu grass intake by cattle. Arch. zootec. [online]. 2014, vol.63, n.241, pp.203-206. ISSN 1885-4494.  https://dx.doi.org/10.4321/S0004-05922014000100021.

The main objective of this study the Marandu grass using total dry matter (CS), hand-plucking sample (PS) and extrusa (EXT) in a completely randomized design. The samples were analyzed for dry matter (DM), crude protein, ether extract, neutral (NDF) and acid-detergent fiber (ADF), hemicellulose, cellulose, lignin, ash, in vitro dry matter digestibility, total, and non fiber carbohydrates. The samples for PS presented DM, NDF and ADF values of 25.19, 65.31, and 28.91 %. The EXT values for NDF and ADF were 73.21 and 33.46 %, respectively, reflecting the selectivity of the animal. The ADF value for CS was 36.01 %, due to the high proportion of senescent material in the forage. The CS and hand plucked samples obtained did not represent the diet consumed by the animals. The chemical composition of the forage is influenced by the different sampling methods.
