Resumo: The aim of this study was was to determine the nutritional requirements of digestible methionine+cystine (M+C) for white-egg layers aged one to six weeks. A completely randomized design with five methionine+cystine levels, six replicates, and 30 birds per experimental unit was adopted. Dietary treatments consisted of five diets supplemented with DL-Methionine with resulted in five levels of digestible methionine + cystine, 80% (0.516%), 90% (0.578%), 100% (0.640%), 110% (0.702%), and 120% (0.764%), based on Brazilian tables of nutritional requirements. Performance, serological blood, and histological data were evaluated. Feed intake, feed conversion, hepatic glycogen deposition, enzymatic activity of alanine aminotransferase and gamma-glutamyl transferase, and serum creatinine and albumin levels had showed a quadratic response to the levels of digestible M+C, with the respective requirements: 89.78% (0.575%), 114.33% (0.732%), 86.50% (0.554%), 100% (0.640%), 100.40% (0.643%), 104.30% (0.668%), and 111.88% (0.716%). Increasing levels of methionine+cystine elevated the relative liver weight and the deposition of hepatic glycogen, in addition to promote higher growth in pullets, with better body weight and body weight gain and feed conversion ratio. Our findings suggest that 0.732% digestible methionine+cystine is recommended, which corresponds to an intake of 151.20 mg/bird/d and a Met+Cys:Lys  ratio 83%, for light pullets from one to six weeks.

Se adoptó un diseño completamente al azar con cinco niveles de metionina + cistina, seis réplicas y 30 aves por unidad experimental. Los tratamientos dietéticos consistieron en cinco dietas suplementadas con DL-Metionina que dieron como resultado cinco niveles de metionina + cistina digeribles, 80% (0.516%), 90% (0.578%), 100% (0.640%), 110% (0.702%), y 120% (0.764%), basado en tablas brasileñas de requerimientos nutricionales. Se evaluaron el rendimiento, la sangre serológica y los datos histológicos. El consumo de alimento, la conversión alimenticia, el depósito de glucógeno hepático, la actividad enzimática de alanina aminotransferasa y gamma-glutamil transferasa, y los niveles séricos de creatinina y albúmina mostraron una respuesta cuadrática a los niveles de M + C digestible, con los requisitos respectivos: 89.78% (0.575 %), 114.33% (0.732%), 86.50% (0.554%), 100% (0.640%), 100.40% (0.643%), 104.30% (0.668%) y 111.88% (0.716%). Los niveles crecientes de metionina + cistina elevaron el peso relativo del hígado y la deposición de glucógeno hepático, además de promover un mayor crecimiento en las pollitas, con un mejor peso corporal y ganancia de peso corporal y relación de conversión alimenticia. Nuestros hallazgos sugieren que se recomienda 0.732% de metionina + cistina digerible, lo que corresponde a una ingesta de 151.20 mg / ave / día y una relación Met + Cys: Lys 83%, para pollitas de una a seis semanas.Objetivou-se determinar a exigência nutricional de metionina+cistina (M+C) digestíveis para aves de reposição leves de 1 a 6 semanas de idade. Utilizou-se um delineamento inteiramente ao acaso com cinco níveis de metionina+cistina, seis repetições e 30 aves por unidade experimental (UE). Os tratamentos dietéticos consistiram em cinco dietas suplementadas com DL-Metionina que resultou em cinco níveis de metionina+cistina digestíveis 80% (0.516%), 90% (0.578%), 100% (0.640%), 110% (0.702%), and 120% (0.764%), baseado nas tabelas brasileiras de exigências nutricionais. Foram avaliados dados de desempenho, sorologia e histologia. Houve comportamento quadrático para consumo de ração, conversão alimentar, deposição de glicogênio hepático, atividade enzimática da alanina aminotransferase, gama-glutamiltransferase e níveis séricos da creatinina e albumina em função dos níveis de M+C digestíveis, sendo as exigências para estas características: 89.78% (0.575%), 114.33% (0.732%), 86.50% (0.554%), 100% (0.640%), 100.40% (0.643%), 104.30% (0.668%), and 111.88% (0.716%), respectivamente. Recomenda-se a utilização de 0,732% de metionina+cistina digestíveis, que corresponde a um consumo de 151.20 mg/ave/dia, e uma relação com a lisina de 83%, para aves de reposição leves de 1 a 6 semanas de idade.Research, Society and Development2020-06-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/524210.33448/rsd-v9i8.5242Research, Society and Development; Vol. 9 No. 8; e74985242Research, Society and Development; Vol. 9 Núm. 8; e74985242Research, Society and Development; v. 9 n. 8; e749852422525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/5242/4518Copyright (c) 2020 Jalceyr Pessoa Figueiredo Junior, Fernando Guilherme Perazzo Costa, Ricardo Romão Guerra, Marcelo Helder Medeiros Santana, Matheus Ramalho Lima, Sarah Gomes Pinheiroinfo:eu-repo/semantics/openAccessFigueiredo Junior, Jalceyr PessoaCosta, Fernando Guilherme PerazzoGuerra, Ricardo RomãoSantana, Marcelo Helder MedeirosLima, Matheus Ramalho dePinheiro, Sarah Gomes2020-08-20T18:00:17Zoai:ojs.pkp.sfu.ca:article/5242Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:28:49.246742Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
