Resumo: | Grains, brans, and vegetable meals may contain non-starch polysaccharides (NSP), which increases viscosity in the gastrointestinal tract (GIT) and interfere with the digestion and absorption of nutrients. This study aimed to evaluate the performance and determine the metabolizable energy of a sorghum-based broiler diet with and without the supplementation of an enzymatic complex. The experiments were conducted in a completely randomized design with 1200 chickens, using sorghum-based feed with and without the addition of 50 g of enzyme-CCE complex (?-glucanase and ?-xylanase), and with two levels of metabolizable energy (ME kg-1): ME; ME + CCE; reduced ME (-50 kcal kg-1); and reduced ME + CCE. The data were subjected to an analysis of variance and the means were compared using a Tukey’s test at the 5% significance level. At 42 and 47 days of age, the living weight of the birds fed with the reduced ME was low, while birds fed with reduced ME + CCE had the same weight as those fed with other energy diets (ME and ME + CCE). Feed conversion was poorest at 47 days of age for the birds on reduced ME diet. In the metabolic test (with fattening diets) to determine AME and AMEn, the reduced ME diet had the lowest result, confirming the effect of the addition of enzymes. The addition of CCE to sorghum-based diets provides enough enzymatic activity to increase the metabolizable energy of the diet (50 kcal of AME) and influence the growth performance of broilers at the slaughtering age. |

Objetivou-se avaliar o desempenho e determinar à energia metabolizável da dieta a base de sorgo, com e sem adição do complexo enzimático (CCE), para frangos de corte. Foram utilizados 1200 frangos de corte, distribuídos em delineamento inteiramente casualisado, alimentados com dois níveis de Energia Metabolizável (EM kg-1), em dietas à base de sorgo com ou sem a adição de 50g de completo enzimático (?-glucanase e ?-xylanase): Energia Metabolizável (EM); Energia Metabolizável com Complexo Enzimático (EM + CCE); EM reduzida (-50kcal EM kg-1) e EM reduzida + CCE. Os dados obtidos foram submetidos à análise de variância e as médias dos tratamentos em cada variável estudada foram comparadas entre si pelo Teste de Tukey a nível de 5% de significância. Aos 42 e 47 dias de idade o peso vivo das aves alimentadas com EM reduzida foi menor, enquanto que EM reduzida + CCE apresentou peso igual ao das dietas EM e EM + CCE. A conversão alimentar aos 47 dias de idade na dieta EM reduzida apresentou o pior resultado. No teste metabólico, com as dietas de engorda, os valores de Energia Metabolizável Aparente e Energia Metabolizável Aparente corrigida para nitrogênio (EMAn) foram menores na dieta com EM reduzida, comprovando o efeito da adição das enzimas. Concluiu-se que a adição de complexo enzimático (?-glucanase and ?-xylanase) melhora o desempenho de frangos de corte e aumenta a energia metabolizável aparente da dieta em 50 kcal.UEL2016-04-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisaPesquisaapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2109810.5433/1679-0359.2016v37n2p959Semina: Ciências Agrárias; Vol. 37 No. 2 (2016); 959-968Semina: Ciências Agrárias; v. 37 n. 2 (2016); 959-9681679-03591676-546Xreponame:Semina.
