Resumo: | Twelve castracted and mature rams of Morada Nova breed were used in a 3 x 2 factorial experiment to study 3 rations containing 60, 70 and 80% of corn crop residue and 23, 13 and 3% corn meal respectively in two different periods. In the second period, animals were rotated among treaments. All rations contained 17% of cottonseed meal, about 9.2% of crude protein in dry matter and were isonitrogenous. There were no significant differences between rations (P>0.05) in digestibilities of dry matter, crude protein, nitrogen-free extract and total digestible nutrients. Differences between rations (P<0.05) were observed in digestibilities of crude fibre, crude energy and ether extract. The digestibility of crude fibre and crude energy declined when corn crop residue was increased from 60 to 70% and remained at that low level at 80%. The digestibility of ether extract exhibited a marked decline when corn crop residue was increased from 70 to 80%. A marginal reduction in the consumption of dry matter was observed with increase in the proportion of corn crop residue, but was not significant (P>0.05). |

No segundo período, foi feita uma rotação dos animais para cada ração. Todas as rações continham 17% de torta de algodão. As rações foram isoprotéicas com 9,2% de proteína bruta na matéria seca. Os resultados mostraram que não houve diferença (P>0,05), entre rações, na digestibilidade da matéria seca, proteína bruta, extrativo não nitrogenado e nutrientes digestíveis totais. Diferença significativa (P<0,05) foi observada na digestibilidade da fibra bruta, extrato etéreo e energia bruta, entre as rações. A digestibilidade da fibra bruta e da energia bruta declinaram quando a proporção de resíduo de cultura foi elevada de 60 para 70%, e permaneceu com nível baixo quando foi elevada para 80%. A digestibilidade do extrato etéreo mostrou marcado declínio quando o resíduo de cultura foi elevado de 70 para 80%. O consumo de matéria seca também decresceu quando o restolho de cultura foi elevado de 70 para 80%. Contudo, a análise estatística mostrou que esta redução não foi significativa (P>0,05).Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraArruda, Francisco de Assis V.Souza, Antonio Alves deJohnson, William L.Pant, Kant P.2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15792Pesquisa Agropecuaria Brasileira; v.19, n.6, jun. 1984; 777-782Pesquisa Agropecuária Brasileira; v.19, n.6, jun. 1984; 777-7821678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15792/9847info:eu-repo/semantics/openAccess2014-04-16T19:22:43Zoai:ojs.seer.sct.embrapa.br:article/15792Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T19:22:43Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
