Resumo: | An experiment was conducted to evaluate the performance, bone densitometry and carcass yield of broilers chicks, using different levels of phytase enzyme. Nine hundred and sixty male one-day-old broiler chicks were used. The birds were distributed in a completely randomized experimental design, involving five treatments and six replications of 32 chicks each. The treatments consisted of a control diet for each phase, and four other diets were formulated adding growing levels of the phytase enzyme (250, 500, 750 and 1,000 FTU of phytase kg-1 feed). When adding the phytase enzyme, the nutritional matrix was valued to guarantee the same nutritional levels as the control diet. In general, the addition of phytase enzyme determined a linear decrease on the performance of the birds. However, the performance obtained with the level of 250 FTU phytase kg-1 feed were no different from the control treatment. The best bone density results were observed in the control treatment with no phytase, and the highest leg and thigh yield were obtained at the level of 514 FTU phytase kg-1. |

Foram utilizados 960 pintainhos de corte com um dia de idade, da marca comercial Ross, distribuídos em um delineamento inteiramente casualizado, com quatro tratamentos mais uma testemunha (quatro níveis da enzima fitase - 250, 500, 750 e 1.000 FTU de fitase kg-1 de ração + testemunha) e seis repetições de 32 aves cada. Ao adicionar a enzima fitase, a matriz nutricional da mesma foi valorizada para garantir os mesmos níveis nutricionais da dieta testemunha. Foram avaliados os índices de desempenho, de densitometria óssea e o rendimento de carcaça e de partes nas diferentes fases de criação. De maneira geral o aumento na inclusão da enzima fitase determinou declínio linear sobre o desempenho das aves. Entretanto, até o nível de 250 FTU de fitase kg-1 de ração não foram observadas diferenças expressivas em relação ao tratamento isento de fitase. Os melhores resultados de densitometria óssea foram observados no tratamento controle sem a adição da enzima fitase e o maior rendimento de coxa+sobrecoxa foi obtido com o nível de 514 FTU de fitase kg-1 de ração.Universidade Estadual Paulista Júlio de Mesquita Filho Faculdade de Ciências Agrárias e Veterinárias de Jaboticabal Departamento de ZootecniaUniversidade Estadual Paulista Júlio de Mesquita Filho Faculdade de Engenharia de Ilha Solteira Departamento de BiologiaUniversidade Estadual Paulista Júlio de Mesquita Filho Faculdade de Ciências Agrárias e Veterinárias de Jaboticabal Departamento de ZootecniaUniversidade Estadual Paulista Júlio de Mesquita Filho Faculdade de Engenharia de Ilha Solteira Departamento de BiologiaEditora da Universidade Estadual de Maringá (EDUEM)Universidade Estadual Paulista (Unesp)Junqueira, Otto Mack [UNESP]Duarte, Karina Ferreira [UNESP]Assuena, Vinícius [UNESP]Filardi, Rosemeire Da Silva [UNESP]Laurentiz, Antonio Carlos De [UNESP]Menegucci, Maria Fernanda Ferreira [UNESP]2014-10-01T13:08:50Z2014-10-01T13:08:50Z2011-09-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article301-307application/pdfhttp://dx.doi.org/10.4025/actascianimsci.v33i3.10702Acta Scientiarum.
