Resumo: | The objective of this research was to study the composition and the nutritive value of ramie (Boehmeria nivea, Gaud) leaf flour. The rat (Ratus norvegicus) was used as experimental model. Chemical determinations showed that ramie leaf flour contained all macronutrients and minerals in excess to the need of growing rats but deficiency of methionine, phosphorus and copper. Complementation of the flour with the three limiting nutrients and vitamins, given to the rats, did not promote growth and caused body weight loss. Pair-fed tests with ramie leaf flour and a reference diet revealed that the rats lost weight and died, due to rejection of the ramie flour and the physiological stress caused by the high content of fiber and phenolic compounds. Autoclaving the ramie flour did not improve the condition and performance of the rats, compared with the unheated flour. Replacement of up to 20% of the reference diet by the complemented ramie flour did not affect the rat growth and performance. Replacements above 25% decreased growth significantly (p≤0.01) and at 40% substitution occurred death of the rats. Treating the diet with 40% substitution by ramie flour with gamma rays (1 Mrad) improved nutritional indexes significantly and eliminated the deaths of the rats. |

Utilizou-se o rato (Ratus norvegicus) como modelo experimental. Determinações químicas revelaram macronutrientes e minerais em excesso para o rato em crescimento, mas deficiência de metionina, fósforo e cobre. A farinha, complementada com esses nutrientes e enriquecida com vitaminas para atender às necessidades dos ratos, não promoveu o crescimento, verificando-se perda de peso dos animais. Testes pareados da farinha com uma dieta-referência revelaram que os ratos perdiam peso e morriam por rejeição à dieta e pelo estresse fisiológico causado pelos elevados teores de compostos fenólicos e componentes fibrosos. A autoclavagem não melhorou as características nutritivas da farinha nem eliminou a perda de peso e a morte dos animais. A substituição da dieta-referência até 20% por farinha de folhas não afetou o crescimento dos ratos. A partir de 25% de substituição observaram-se diferenças significativas; aos 40% de substituição verificaram-se mortes. Tratamento da dieta contendo 40% de farinha de folhas de rami com raios gama (1 Mrad) resultou em melhora significativa do valor nutritivo e na eliminação da mortalidade dos ratos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraDuarte, Ângela de AlmeidaSgarbieri, Valdemiro CarlosJúnior, Romeu Benatti1997-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4775Pesquisa Agropecuaria Brasileira; v.32, n.12, dez. 1997; 1295-1302Pesquisa Agropecuária Brasileira; v.32, n.12, dez. 1997; 1295-13021678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4775/7257info:eu-repo/semantics/openAccess2015-05-06T18:40:13Zoai:ojs.seer.sct.embrapa.br:article/4775Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2015-05-06T18:40:13Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
