Resumo: | The objective of this work was to evaluate the influence of protein sources on feedlot lambs performance, carcass and meat characteristics, and to estimate starch digestibility of high grain diets. Twenty-eight Santa Inês ram lambs were selected in a complete randomized block design, according to body weight and age in the beginning of the experiment. Protein sources were the following meals: soybean, peanut, canola, and cottonseed in isonitrogenous diets with 90% concentrate and 10% roughage (coast-cross hay). Four ram lambs (48 kg) were used to determine starch digestibility in a 4x4 latin square design, and starch digestibility was estimated by fecal concentration of starch. There were no differences (p > 0.05) for dry matter intake, average daily gain, feed conversion, carcass characteristics and meat quality, among the protein sources evaluated. Determination coefficient for starch digestibility was 93%. Fecal starch content is an accurate indicator of the starch digestibility estimation in lambs feeding high grain diets, independently of the protein source used. |

Foram distribuídos 28 cordeiros Santa Inês, em blocos completos ao acaso, de acordo com o peso vivo e a idade, no início do experimento. As fontes protéicas foram os farelos de: soja, amendoim, canola e algodão, em dietas isonitrogenadas com 90% de concentrado e 10% de volumoso (feno de coast-cross). Na determinação da digestibilidade, foram utilizados quatro borregos em delineamento experimental em quadrado latino 4x4, e a digestibilidade do amido foi estimada a partir do teor de amido fecal. Não houve diferenças (p > 0,05) quanto ao consumo de matéria seca, ganho de peso vivo médio, conversão alimentar, características da carcaça e da carne, entre as fontes protéicas avaliadas. A digestibilidade do amido apresentou coeficiente de determinação de 93%. Independentemente da fonte protéica utilizada, o teor de amido nas fezes é um indicador eficiente na estimativa da digestibilidade do amido de dietas com alta proporção de concentrado para cordeiros.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraQueiroz, Mário Adriano ÁvilaSusin, IvanetePires, Alexandre VazMendes, Clayton QuirinoGentil, Renato ShinkaiAlmeida, Omer CavalcantiAmaral, Rafael Camargo doMourão, Gerson Barreto2008-10-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/434Pesquisa Agropecuaria Brasileira; v.43, n.9, set. 2008; 1193-1200Pesquisa Agropecuária Brasileira; v.43, n.9, set. 2008; 1193-12001678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/434/5500https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/434/317info:eu-repo/semantics/openAccess2012-06-17T11:43:23Zoai:ojs.seer.sct.embrapa.br:article/434Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2012-06-17T11:43:23Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
