Resumo: The objective was to evaluate the effect of breeding laying hens system on performance, egg quality and rectal temperature of birds. One hundred laying hens Hy-Line W-36 and 100 laying hens Hy-Line Brown with 30 weeks of age distributed in a completely randomized design in a factorial 2 x 2, wi five replicates and ten birds each. The performance variables studied were egg with eight, feed intake, feed conversion (kg / kg), feed conversion (kg / dz) and egg production. For quality were analyzed percentage of albumen, yolk percentage, yolk index, Haugh unit, shell thickness and non-commercial eggs. Rectal temperature was assessed at 34; 38; 42 and 46 weeks of age. The results were submitted to analysis of variance and means compared by Tukey test at 5% probability, using the SAS statistical software. The conversion (kg / dz), yolk percentage, yolk index, Haugh unit, percentage of egg production, not commercial eggs percentage did not differ between housing systems. The feed intake, feed conversion (kg / kg), and egg weight were higher for the floor system. Rectal temperature was higher in breeding system in cages. Brown birds had higher yolk percentage, yolk index and Haugh unit. Lightweight birds showed higher percentage albumen, shell thickness. It was concluded that laying hens can achieve satisfactory results when compared to conventional cage rearing system.

Se utilizaron cien gallinas ponedoras Hy-Line W-36 y 100 gallinas ponedoras Hy-Line Brown de 30 semanas de edad en un diseño completamente al azar en un esquema factorial 2 x 2, con cinco repeticiones y diez aves por unidad experimental. Las variables de rendimiento estudiadas fueron peso del huevo, consumo de alimento, conversión alimenticia (kg / kg), conversión alimenticia (kg / dz) y producción de huevo. Para la calidad, se analizaron el porcentaje de albúmina, el porcentaje de yema, el índice de yema, la unidad Haugh, el grosor de la cáscara y los huevos no comerciales. La variable de temperatura rectal se evaluó en el período 34; 38; 42 y 46 semanas de edad. Los resultados se sometieron al análisis de varianza y las medias comparadas por la prueba de Tukey con una probabilidad del 5%, con la ayuda del programa estadístico SAS. La conversión (kg / dz), porcentaje de yema, índice de yema, unidad Haugh, porcentaje de producción de huevo, porcentaje de huevo no comercial no difirió entre los sistemas de cría. La ingesta de alimento, la conversión alimenticia (kg / kg) y el peso del huevo fueron mayores para el sistema de piso. La temperatura rectal fue mayor en el sistema de cría en jaula. Las aves semipesadas presentaron mayor porcentaje de yema, índice de yema y unidad Haugh. Las aves ligeras presentaron mayor porcentaje de albúmina y grosor de corteza. Se concluyó que las gallinas ponedoras pueden lograr resultados satisfactorios en comparación con el sistema convencional de cría en jaulas.Objetivou-se avaliar o efeito do sistema de criação de poedeiras comerciais sobre o desempenho, qualidade dos ovos e temperatura retal das aves. Foram utilizadas 100 poedeiras da linhagem Hy-Line W-36 e 100 poedeiras Hy-Line Brown com 30 semanas de idade distribuídas em delineamento inteiramente casualizado em esquema fatorial 2 x 2, com cinco repetições e dez aves por unidade experimental. As variáveis de desempenho estudadas foram peso do ovo, consumo de ração, conversão alimentar (kg/kg), conversão alimentar (kg/dz) e produção de ovos. Para qualidade foram analisados percentual de albúmen, percentual de gema, índice de gema, Unidade Haugh, espessura da casca e ovos não comerciais. A variável de temperatura retal foi avaliada no período de 34; 38; 42 e 46 semanas de idade. Os resultados foram submetidos à análise de variância e as médias comparadas pelo teste Tukey a 5% de probabilidade, com auxílio do programa estatístico SAS. A conversão (kg/dz), percentual de gema, índice de gema, Unidade Haugh, percentual de produção de ovos, percentual de ovos não comerciais não diferiram entre os sistemas de criação. O consumo de ração, conversão alimentar (kg/kg) e peso dos ovos foram maiores para o sistema de piso. A temperatura retal foi maior no sistema de criação em gaiolas. Aves semipesadas apresentaram maior percentual de gema, índice de gema e Unidade Haugh. Aves leves apresentaram maior percentual de albúmen e espessura da casca. Conclui-se que poedeiras em sistema de criação em piso podem alcançar resultados satisfatórios quando comparado com sistema de criação em gaiolas convencionais.Research, Society and Development2020-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/220910.33448/rsd-v9i2.2209Research, Society and Development; Vol. 9 No. 2; e140922209Research, Society and Development; Vol. 9 Núm. 2; e140922209Research, Society and Development; v. 9 n. 2; e1409222092525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/2209/1780Copyright (c) 2020 PAULO VITOR DIVINO XAVIER DE FREITAS, Paulo Ricardo de Sá da Costa Leite, Mônica Maria de ALmeira Brainer, Leticia Mariano Barbosa, Vanessa Cristina de Souza Resende, Júlia Marixara Sousa da Silvainfo:eu-repo/semantics/openAccessFreitas, Paulo Vitor Divino Xavier deLeite, Paulo Ricardo de Sá da CostaBrainer, Mônica Maria de ALmeiraResende, Vanessa Cristina de SouzaBarbosa, Leticia MarianoSilva, Júlia Marixara Sousa da2020-08-20T18:08:48Zoai:ojs.pkp.sfu.ca:article/2209Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:26:56.244177Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
