Resumo: | The objective of this work was to evaluate the digestibility of sorghum (Sorghum bicolor) or millet (Pennisetum glaucum) diets with the addition of a commercial enzymatic complex formed by amylase, carbohydrases, proteases and phytase, and broiler performance. For performance evaluation, 1,800 male broilers were distributed in a randomized complete block design in a 2x2 factorial arrangement, with four treatments (sorghum or millet diet with or without addition of enzymatic complex), and five replicates of 60 birds per experimental unit. In the metabolism assays carried out at 10 to 14 and 24 to 28 days, 420 male broilers were distributed in a completely randomized block design in a 2x2 factorial arrangement (millet or sorghum diet with or without addition of enzymatic complex). Data were submitted to variance analysis and averages were compared by the F test for orthogonal contrasts. In diets formulated with sorghum, the addition of the enzymatic complex provided better coefficients of digestibility of fat and nitrogen. The addition of the enzymatic complex in diets formulated with sorghum improves feed conversion ratio only in the initial phase of raising broilers, while the addition of the enzymatic complex does not improve broiler performance in diets formulated with pearl millet. |

Para avaliação de desempenho, foram alojados 1.800 pintos de corte machos em delineamento em blocos ao acaso, em arranjo fatorial 2x2, com quatro tratamentos (rações com sorgo ou milheto com ou sem adição de complexo enzimático) e cinco repetições com 60 aves por unidade experimental. Nos ensaios de metabolismo realizados dos 10 aos 14 e dos 24 aos 28 dias, foram distribuídos 420 pintos machos em delineamento inteiramente casualizado, em esquema fatorial 2x2 (rações com milheto ou sorgo com ou sem adição de complexo enzimático). Os dados foram submetidos à análise de variância e as médias comparadas com o teste F para contrastes ortogonais. Nas rações elaboradas com sorgo, a adição do complexo enzimático proporcionou melhores coeficientes de digestibilidade da gordura e do nitrogênio. A adição de complexo enzimático em rações formuladas com sorgo melhora a conversão alimentar somente na fase inicial de criação dos frangos, enquanto a adição de complexo enzimático não melhora o desempenho de frango nas rações elaboradas com milheto.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraLeite, Paulo Ricardo Sá da CostaLeandro, Nadja Susana MogycaStringhini, José HenriqueCafé, Marcos BarcellosGomes, Natali AlmeidaJardim Filho, Roberto de Moraes2011-06-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/8597Pesquisa Agropecuaria Brasileira; v.46, n.3, mar. 2011; 280-286Pesquisa Agropecuária Brasileira; v.46, n.3, mar. 2011; 280-2861678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/8597/6267https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/8597/4322info:eu-repo/semantics/openAccess2012-06-17T12:07:07Zoai:ojs.seer.sct.embrapa.br:article/8597Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2012-06-17T12:07:07Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
