Resumo: | The objective of this study was evaluate the per-formance, egg quality and production costs of commercial laying hens fed with rice meal and formulated on total and digestible amino acids basis. During 5 periods of 28 days 192 Lohmann LSL hens 25 weeks of age were distributed in a completely random experiment in a factorial scheme with 8 treatments and 3 replications of 8 birds each. The factorial scheme consisted in two amino acid recommen-dation (total and digestible) and four inclusion levels of rice meal (0, 5, 10 and 15%). The performance and egg quality were evaluated during five cycles of 28 days. Un-der the conditions of this experiment, the use of digest-ible amino acid values determined low performance and higher production cost in comparison with the total amino acid values. The diets formulated with different rice meal levels did not affected performance and egg quality pa-rameters evaluated, however, the use of rice meal in lay-ing hens diets should be determined depending on avail-ability and cost, while was observed over 6% of inclusion the egg production costs was increased.KEY-WORDS: Alternative feed, amino acid recommendation, egg quality, performance. |

Empregaram-se 192 poedeiras da linhagem Lohmann LSL com 26 semanas de idade, distribuídas em um delineamento inteiramente ao acaso em esquema fato-rial 2 x 4 (duas recomendações de aminoácidos x 4 níveis de inclusão do farelo de arroz), sendo utilizadas três repe-tições de oito aves por tratamento. Os tratamentos consis-tiram da combinação de duas recomendações de aminoá-cidos (totais ou digestíveis) e quatro níveis de inclusão do farelo de arroz (0 %, 5 %, 10 % e 15 %). Durante cinco ciclos de 28 dias, avaliaram-se parâmetros de desempenho e qualidade de ovos. As recomendações de aminoácidos digestíveis determinaram pior desempenho e maior cus-to de produção de ovos em relação às recomendações de aminoácidos totais. Os níveis de inclusão do farelo de ar-roz não afetaram de forma significativa o desempenho ou a qualidade dos ovos, entretanto acima de 6,0% de farelo de arroz ocorre aumento no custo de produção dos ovos, ficando a utilização desse ingrediente dependente da dis-ponibilidade e custo.PALAVRAS-CHAVES: Alimento alternativo, desempenho, qualidade de ovos, recomendação de aminoácidos.Universidade Federal de Goiás2007-09-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresPesquisaapplication/pdfhttps://revistas.ufg.br/vet/article/view/167710.5216/cab.v8i3.1677Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 8 No. 3 (2007); 397-406Ciência Animal Brasileira / Brazilian Animal Science; v. 8 n. 3 (2007); 397-4061809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/1677/1647Filardi, Rosemeire da SilvaJunqueira, Otto MackLaurentiz, Antonio Carlos deCasartelli, Elenice MariaAssuena, ViniciusPileggi, JeanineDuarte, Karina Ferreirainfo:eu-repo/semantics/openAccess2007-09-15T15:26:12Zoai:ojs.revistas.ufg.br:article/1677Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:54:57.503600Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true |
