Resumo: This work was carried out aiming to compare lignin concentration of some grass forages through two analytical methods (acid detergent lignin - ADL and permanganate lignin - PerL) as well to verify a possible relationship of lignin concentration with fiber digestion of the following grass hays: andropogon (Andropogon gayanus); oats (Avena sativa); a good quality and another of poor quality coast-cross (Cynodon dactylon). Acid detergent and permanganate lignin values were different (p £ 0.05) among the hays, however PerL concentrations were consistently lower than ADL values. There were differences (p £ 0.05) among the digestibility of neutral and acid detergent fiber fractions, however a clear relationship between these values with lignin concentration could not be assessed. The data suggested that lignin concentration, taken individually, is not the only factor to explain a given value of digestibility.

Os valores de LDA e LPer foram diferentes (p £ 0,05) entre as gramíneas estudadas, com as concentrações de LPer consistentemente mais baixas do que as de LDA. Foram detectadas diferenças (p £ 0,05) nos valores de digestibilidade da fibra em detergente neutro (FDN) e da fibra em detergente ácido (FDA), porém, não foi detectada clara relação desses valores com teores de lignina. Os dados sugerem que a concentração de lignina não é o principal fator a explicar um dado valor de digestibilidade.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFukushima, Romualdo ShigueoRosa, Artur Jordão de Magalhãesde Lima, César Gonçalvesda Cunha, José Aparecido1999-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5283Pesquisa Agropecuaria Brasileira; v.34, n.6, jun. 1999; 1025-1030Pesquisa Agropecuária Brasileira; v.34, n.6, jun. 1999; 1025-10301678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5283/2475info:eu-repo/semantics/openAccess2010-07-12T11:47:21Zoai:ojs.seer.sct.embrapa.br:article/5283Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-07-12T11:47:21Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
