Chemical composition and in-vitro digestibility}, volume={82}, url={https://revistas.upr.edu/index.php/jaupr/article/view/3817}, DOI={10.46429/jaupr.v82i1-2.3817}, abstractNote={An experiment was conducted to determine the effects of including legume species (<em>Leucaena leucocephala</em>, <em>Stylosanthes guianensis</em>, <em>Centrosema pubescens</em> Benth or <em>Neonotonia wightii</em>) at levels of 0, 5, 10, 20, and 40% of the dry matter on the chemical composition (crude protein, CP neutral detergent fiber, NDF; acid detergent fiber, ADF) and on in vitro dry matter digestibility (IVDMD) of mixtures of each legume with four grass species (<em>Cynodon nlemfuensis</em> Vanderyst, <em>Panicum maximum</em> jacq., <em>Pennisetum purpureum</em> Schum., or <em>Sorghum bicolor</em> (L.) Moench). Of the legume species included, <em>Leucaena leucocephala</em> and <em>Centrosema pubescens</em> had the highest CP content and IVDMD, respectively. For the legumes, the mean CP and IVDMD values, respectively, were <em>Leucaena leucocephala</em>, 21.98 and 68.09; <em>Stylosanthes guianensis</em>, 13.70 and 63.44; <em>Centrosema pubescens</em>, 18.29 and 68.60; and <em>Neonotonia wightii</em>, 16.72 and 66.64%. For the grasses, they were, respectively, <em>Cynodon nlemfuensis</em>, 8.27 and 61.38; <em>Panicum maximum</em>, 7.64 and 60.06; <em>Pennisetum purpureum</em>, 8.02 and 53.47; and<em> Sorghum bicolor</em>, 7.57 and 59.62%. Neutral detergent fiber and ADF contents were higher in the grasses (<em>Cynodon nlemfuensis</em>, 73.03 and 44.45; <em>Panicum maximum</em>, 65.27 and 49.06; <em>Pennisetum purpureum</em>, 69.26 and 51.88; and <em>Sorghum bicolor</em>, 60.24 and 50.99%, respectively) than in the fegumes (<em>Leucaena leucocephala</em>, 50.52 and 28.50; <em>Stylosanthes guianensis</em>, 52.57 and 36.63; <em>Centrosema pubescens</em>, 58.43 and 34.84; and <em>Neonotonia wightii</em>, 54.11 and 33.23%, respectively). The chemical composition of the forages varied according to the relative proportions of the species included, as expected. However, the effects on IVDMD were not additive; rather, associative effects, mainly antagonistic, were observed in most of the mixtures.}, number={1-2}, journal={The Journal of Agriculture of the University of Puerto Rico}, author={Rodríguez, Abner A. and Riquelme, Ernesto O. and Randel, Paul F.}, year={1998}, month={Apr.}, pages={25–38} }
