Resumo: | The objective of this study was to evaluate the effect of L-glutamine and organic zinc in diets for broilers on the parameters of carcass and meat yields, chemical composition and nutrient deposition in poultry carcasses at 21 days of age. Ross chicks (n=630) were distributed in a 2 x 3 + 1 completely randomized design, using levels of 1 and 2% L-glutamine with 0, 90 and 120 mg organic zinc/kg feed and a control diet, totaling seven treatments and five repetitions, with 18 birds each. The combination of L-glutamine and organic zinc did not influence the parameters evaluated. However, zinc supplementation alone interfered in a linearly increasing way with breast yield, in a linearly decreasing way with abdominal fat, and protein content in the carcass. Still, independently, regarding the chemical composition of poultry carcass, the level of 2% L-glutamine provided a higher concentration of dry matter and ash. Likewise, it showed the highest ash deposition. Supplementation of 2% L-glutamine in broiler diets improves the dry matter and the ash content in poultry carcasses and the inclusion of organic zinc positively interferes with the yield of breast, abdominal fat and crude protein |

Foram utilizados 630 pintos da linhagem Ross, distribuídas em delineamento inteiramente casualizados, em esquema 2 x 3 + 1, sendo utilizados os níveis de 1 e 2% de L-glutamina com 0, 90 e 120 mg de zinco orgânico/kg de ração e uma dieta controle, totalizando sete tratamentos e cinco repetições, com 18 aves cada. A associação de L-glutamina e zinco orgânico não influenciaram nos parâmetros avaliados. No entanto, a suplementação isolada de zinco interferiu de forma linear crescente para o rendimento de peito, de forma linear decrescente para a gordura abdominal e de maneira linear decrescente quanto ao teor de proteína na carcaça. Ainda, de maneira independente, quanto à composição química na carcaça das aves, o nível de 2% de L-glutamina proporcionou maior concentração de matéria seca e cinzas. Da mesma forma, apresentou a maior deposição de cinzas. A suplementação de 2% de L-glutamina em dietas para frangos de corte melhora o teor de matéria seca e de cinzas na carcaça das aves e a inclusão de zinco orgânico interfere positivamente no rendimento de peito, gordura abdominal e proteína bruta.Sociedade de Medicina Veterinária do Estado do Rio de Janeiro.2021-05-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionpeer reviewedAvaliado pelos paresapplication/pdfhttps://rbmv.org/BJVM/article/view/113310.29374/2527-2179.bjvm113320Brazilian Journal of Veterinary Medicine; Vol. 42 No. 1 (2020); e113320Revista Brasileira de Medicina Veterinária; v. 42 n. 1 (2020); e1133202527-21790100-2430reponame:Brazilian Journal of Veterinary Medicineinstname:Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)instacron:SBMVenghttps://rbmv.org/BJVM/article/view/1133/1018Copyright (c) 2020 Daniela Cristina Pereira Lima, Elvania Maria da Silva Costa Moreira, Sandra Regina Gomes da Silva, Mirian Lima Fernandes, Mabell Nery Ribeiro, Tatiele Pereira Araújo , Jackelline Cristina Ost Lopes, Jefferson Douglas Martins Ferreira , João Batista Lopes , Agustinho Valente de Figueiredo http://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessPereira Lima, Daniela Cristina da Silva Costa Moreira, Elvania Maria Gomes da Silva, Sandra Regina Lima Fernandes, MirianNery Ribeiro, Mabell Pereira Araújo , Tatiele Cristina Ost Lopes, Jackelline Martins Ferreira , Jefferson DouglasBatista Lopes , João Valente de Figueiredo , Agustinho 2021-05-13T13:46:40Zoai:ojs.rbmv.org:article/1133Revistahttps://rbmv.org/BJVMONGhttps://rbmv.org/BJVM/oaicontato.rbmv@gmail.com2527-21790100-2430opendoar:2021-05-13T13:46:40Brazilian Journal of Veterinary Medicine - Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)false |
