The management of Xaraés palisade grass was similar in both systems, differing only regarding shading in the ICLF system provided by eucalyptus trees (average 65% crown cover). Grass samples were incubated for 0, 3, 6, 9, 12, 24, 36, 48, 72, and 96 hours. Considering the passage rate 2% h-1, the Xaraés palisade grass of ICL system had greater NDF effective degradability in relation to ICLF (46.38 vs 44.98%). However, the palisade grass CP potential degradability was greater in the ICLF than in the ICL system (68.92% vs. 65.40%). The presence of trees in the pasture has effect on nutritional traits of the Xaraés palisade grass, increasing its protein content and degradability and reducing its fiber degradability. 2021 artículo científico 1806-2636 https://www.redalyc.org/articulo.oa?id=303168054049 https://www.redalyc.org/journal/3031/303168054049/ https://www.redalyc.org/journal/3031/303168054049/html/ https://www.redalyc.org/journal/3031/303168054049/303168054049.epub https://www.redalyc.org/journal/3031/303168054049/movil 10.4025/actascianimsci.v43i1.53004 en http://www.redalyc.org/revista.oa?id=3031 Acta Scientiarum.
