Resumo: | The objectives of this work were to evaluate animal production and its relationship with pasture characteristics of Brachiaria brizantha cultivars Marandu, Xaraés and Piatã. The experiment had a randomized complete block design, with three treatments and two replicates. Two-ha paddocks were divided into two and submitted to alternated grazing, with 28 days of grazing and 28 days of rest. Three tester steers were kept in each paddock; additional steers were placed in each paddock by the put-and-take technique, to assure post-grazing residues of about 3 Mg ha-1 of dry matter. The pastures were sampled monthly to estimate the nutritive value of the forage. The animals were weighted, and the stocking rate was adjusted twice a week. Despite the lower average daily gain (ADG), in the cv. Xaraés pasture, the stocking rate was greater, which resulted in greater productivity, in comparison with cvs. Marandu and Piatã. The pasture with cv. Piatã had the highest ADG. These results indicate that cvs. Xaraés and Piatã are new alternatives for Cerrado pastures. The choice of the forage cultivar should fit the animal and production system targets. |

O delineamento experimental foi o de blocos ao acaso, com três tratamentos e duas repetições. Os piquetes com 2 ha foram subdivididos em dois e submetidos ao pastejo alternado, com 28 dias de utilização e 28 dias de descanso. Foram utilizados três novilhos teste, por piquete, e novilhos reguladores para manter resíduos pós-pastejo em torno de 3 Mg ha-1 de matéria seca. Mensalmente, os pastos foram avaliados para se estimar o valor nutritivo da forragem. Os animais foram pesados, e as taxas de lotação foram ajustadas duas vezes por semana. No pasto da cv. Xaraés, apesar do menor ganho médio diário (GMD) dos animais, a taxa de lotação foi maior, o que resultou em maior produtividade da cv. Xaraés, em comparação às cvs. Marandu e Piatã. No pasto da cv. Piatã, houve aumento do GMD, o que indica que as cvs. Xaraés e Piatã são novas alternativas para a diversificação dos pastos no Cerrado. Assim, a escolha da forragem deve se dar em razão da meta do sistema de produção, ou seja, a produção por animal ou por área.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFUNDECT, CNPq e CAPESEuclides, Valéria Pacheco BatistaMacedo, Manuel Cláudio MottaValle, Cacilda Borges doDifante, Gelson dos SantosBarbosa, Rodrigo AmorimCacere, Everton Ronaldo2009-03-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/1239Pesquisa Agropecuaria Brasileira; v.44, n.1, jan. 2009; 98-106Pesquisa Agropecuária Brasileira; v.44, n.1, jan. 2009; 98-1061678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/1239/5635https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/1239/844https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/1239/845info:eu-repo/semantics/openAccess2014-11-18T18:31:28Zoai:ojs.seer.sct.embrapa.br:article/1239Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-11-18T18:31:28Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
