Resumo: | The objective of this work was to evaluate the effects of dietary glutamine and glutamic acid supplementation on carbon turnover (δ13C) in the muscles of piglets, on animal performance, and on feed economic feasibility. The diets consisted of: control (C), 1% glutamine (G), and 1% glutamic acid (GA). In experiment I, 111 piglets were used to assess carbon turnover in the Masseter, Psoas major, and Abdominal internal oblique muscles in terms of their isotopic composition and 13C substitution over time. In experiment II, 72 piglets were assigned randomly to blocks (eight replicates per treatment and three animals per experimental unit), in order to evaluate animal performance and feed economic feasibility. The GA diet promoted the best 13C acceleration in the studied muscles. No diet effects were observed on performance variables. The G and GA diets presented higher costs than the C diet. Although supplementation with 1% glutamine or glutamic acid accelerates carbon turnover in the studied muscles, which suggests a faster recovery during post-weaning and proves the anabolic effect of these additives, its use is not economically viable for weanling piglets. |

As dietas consistiram em: controle (C), 1% de glutamina (G) e 1% de ácido glutâmico (AG). No experimento I, 111 leitões foram usados para avaliar o turnover do carbono nos músculos Masseter, Psoas major e Abdominal internal oblique, quanto à composição isotópica e à substituição do 13C no tempo. No experimento II, 72 leitões foram alocados em blocos ao acaso (oito repetições por tratamento e três animais por unidade experimental), para avaliar o desempenho dos animais e a viabilidade econômica das rações. A dieta AG promoveu a melhor aceleração de 13C nos músculos estudados. Não se constatou efeito das dietas nas variáveis de desempenho. As dietas G e AG apresentaram maiores custos que a dieta C. Embora a suplementação com 1% de glutamina ou ácido glutâmico acelere o turnover do carbono nos músculos estudados, o que sugere rápida recuperação no pós-desmame e comprova o efeito anabólico desses aditivos, seu uso não é economicamente viável para leitões recém-desmamados.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFundação de Amparo à Pesquisa do Estado de São Paulo (Fapesp, process No. 2011/17844-1)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq, process No. 501190/2013-9)Amorim, Alessandro BorgesDib Saleh, Mayra AntonMiassi, Gabriela de MelloBerto, Dirlei Antonio2018-03-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/25389Pesquisa Agropecuaria Brasileira; v.53, n.2, fev. 2018; 229-237Pesquisa Agropecuária Brasileira; v.53, n.2, fev. 2018; 229-2371678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/25389/14143https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/25389/17163https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/25389/17164Direitos autorais 2018 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2018-03-16T20:48:08Zoai:ojs.seer.sct.embrapa.br:article/25389Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2018-03-16T20:48:08Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
