Resumo: | The objective of this work was to evaluate the effect of different leaf lamina biomass over animal performance. A mixture of oat (Avena strigosa Schreb) and Italian ryegrass (Lolium multiflorum Lam.) was used to determine adequate levels of leaf lamina biomass for pasture management. Two trials were made, in 2002 and 2003 cool seasons. In 2002 evaluation, leaf lamina biomass values were of 360 kg ha-1 (low) and 630 kg ha-1 (high). In 2003, values obtained for leaf lamina biomasses were of 352, 422 and 507 kg ha-1, being classified as low, medium and high, respectively. Grazing method was continuous, with variable stocking rate; testing animals were calves of Charolais breed and its crosses with Nelore breed, with initial age of nine months. Evaluated variables in animal production, in both years, were: average daily gain, stocking rate and live weight gain per area. Leaf lamina biomasses evaluated are not limiting factors to animal performance. |

Utilizou-se mistura de aveia (Avena strigosa Schreb) e azevém (Lolium multiflorum Lam.), para determinar quantidades adequadas de sua biomassa no manejo da pastagem. Foram realizados dois experimentos, na estação fria de 2002 e 2003. Na avaliação de 2002, os valores de biomassa de lâminas foliares foram de 360 kg ha-1 (baixa) e 630 kg ha-1 (alta). Em 2003, foram obtidas biomassas de 352, 422 e 507 kg ha-1, classificadas como baixa, média e alta, respectivamente. O método de pastejo foi contínuo, com taxa de lotação variada; os animais utilizados foram terneiros da raça Charolês e cruzados com Nelore, com idade inicial de nove meses. As variáveis de produção animal avaliadas, nos dois anos, foram: ganho médio diário, carga animal e ganho de peso vivo por área. As distintas biomassas de lâminas foliares mantidas não são fatores limitantes ao desempenho animal.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBandinelli, Duilio GuerraQuadros, Fernando Luiz Ferreira deMaixner, Antônio RudiSomões, Luiz Felipe CattaniMartins, Carlos Eduardo NogueiraSilva, Alexandre Coradini Fontoura daTrevisan, Naíme de BarcellosBrum, Marcos da SilvaAurélio, Niumar Dutra2005-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7089Pesquisa Agropecuaria Brasileira; v.40, n.12, dez. 2005; 1231-1238Pesquisa Agropecuária Brasileira; v.40, n.12, dez. 2005; 1231-12381678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7089/4137info:eu-repo/semantics/openAccess2014-09-19T16:59:10Zoai:ojs.seer.sct.embrapa.br:article/7089Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-19T16:59:10Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
