Resumo: The objective of this work was to evaluate the nutritive value, sward structure, herbage intake and animal performance on xaraés palisade grass (Urochloa brizantha cv. Xaraés) pastures with 15, 30 and 45 cm sward heights, under continuous stocking, during rainy season. Monthly, the pastures were sampled for estimating the sward characteristics and the animals were weighted. Forage production decreased with the increase of grazing intensity; however, the 15-cm sward height pasture showed the greatest nutritive value. Dry matter intake was lower in the 15-cm pasture (1.89% live weight – LW) than in the 30 cm (2.26% LW) and 45 cm (2.34% LW) pastures. The average daily gain was similar among the different sward heights, with 730 g per steer average. The stocking rates were lower for the 45 cm (2.0 AU ha-1) and 30 cm (2.5 AU ha-1) pastures than for the 15 cm (3.5 AU ha-1) pasture. There was a greater gain per area for the 15 cm (678 kg ha-1) pasture than for the 45 cm (324 kg ha-1) pasture.

Xaraés), manejados a 15, 30 e 45 cm de altura, sob lotação contínua, durante o período das águas. Mensalmente, foram realizadas amostragens para estimar as características dos pastos e determinar o peso dos animais. A produção de forragem decresceu com o aumento da intensidade de pastejo; no entanto, o pasto com 15 cm de altura apresentou o maior valor nutritivo. O consumo de matéria seca foi menor no pasto com 15 cm (1,89% peso vivo – PV) do que nos com 30 cm (2,26% PV) e 45 cm (2,34% PV). O ganho médio diário foi semelhante entre as diferentes alturas de manejo, em média, 730 g por novilho. As taxas de lotação foram menores para os pastos com 45 cm (2,0 UA ha-1) e 30 cm (2,5 UA ha-1) do que para o com 15 cm (3,5 UA ha-1). Houve maior ganho por área no pasto com 15 cm (678 kg ha-1) do que no com 45 cm (324 kg ha-1).Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFUNDECT, CNPqCarloto, Marciele NevesEuclides, Valéria Pacheco BatistaMontagner, Denise BaptaglinLempp, BeatrizDifante, Gelson dos Santosde Paula, Cássia Cristina Lemes2011-03-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/8550Pesquisa Agropecuaria Brasileira; v.46, n.1, jan. 2011; 97-104Pesquisa Agropecuária Brasileira; v.46, n.1, jan. 2011; 97-1041678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/8550/6188https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/8550/4270info:eu-repo/semantics/openAccess2014-05-16T17:32:59Zoai:ojs.seer.sct.embrapa.br:article/8550Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-05-16T17:32:59Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
