Resumo: | The objective was to evaluate the productivity, chemical composition, ruminal degradability of dry matter and digestibility of BRS capiaçu grass (Pennisetum purpureum Schum.) managed at five regrowth ages. A completely randomized design with ten replications was used in the BRS capiaçu elephant grass subjected to five cutting intervals (30, 60, 90, 120 and 150 days) in the summer, making a total of 50 plots with a useful area of 4 x 2 m. There were daily increases in the dry matter production in the order of 382 kg ha-1, with 49,859 kg ha-1 being produced at 150 regrowth days. The dry matter content and organic matter linearly increased (P < 0.01) at different regrowth ages. The crude protein content, in vitro dry matter digestibility and in vitro digestibility of neutral detergent fiber linearly reduced (P < 0.01) 0.037%, 0.196% and 0.256% per day, respectively. Potential degradability of dry matter decreased from 68.9% at 30 days to 44.7% at 150 regrowth days (0.194 percentage units per day). The rate of degradation of fraction B 'c' was not modified (P = 0.94), averaging 1.46% hour-1. In the cultivation of BRS capiaçu elephant grass in the summer season, in the northern region of Minas Gerais, the age for harvesting between 90 and 120 days of regrowth is recommended. |

Foi utilizado o delineamento inteiramente casualizado com dez repetições, na cultivar BRS capiaçu de capim-elefante submetida a cinco intervalos de corte (30, 60, 90, 120 e 150 dias) no verão, perfazendo um total de 50 parcelas com área útil de 4 x 2 m. Foram verificados incrementos diários na produção de matéria seca na ordem de 382 kg ha-1, sendo 49.859 kg ha-1 a produção aos 150 dias de rebrota. O teor de matéria seca e matéria orgânica aumentaram (P < 0,01) linearmente nas diferentes idades de rebrota. O teor de proteína bruta, digestibilidade in vitro da matéria seca e digestibilidade in vitro da fibra em detergente neutro reduziram (P < 0,01) linearmente de 0.037%, 0.196% e 0.256% por dia, respectivamente. A degradabilidade potencial da matéria seca reduziu de 68.9% aos 30 dias para 44.7% com 150 dias de rebrota (0.194 unidades percentuais por dia). A taxa de degradação da fração B ‘c’ não foi modificada (P=0.94), média de 1.46% hora-1. No cultivo do Capim-Elefante BRS capiaçu na estação verão, na região norte de Minas Gerais, recomenda-se a idade para colheita entre 90 e 120 dias de rebrota.UEL2019-07-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa científica de campo e laboratórioapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3454410.5433/1679-0359.2019v40n5p2045Semina: Ciências Agrárias; Vol. 40 No. 5 (2019); 2045-2056Semina: Ciências Agrárias; v. 40 n. 5 (2019); 2045-20561679-03591676-546Xreponame:Semina.
