Resumo: This experiment was undertaken to determine the effect of one multienzimatic complex by using amilase, protease and xilanase suplemented in the corn and soybean meal based diets on the performance of broiler chickens. Eight hundred and nineteen broiler chicks were utilized. The chickens were distribuited in a 13 (thirteen) treatments with three replicates and 21 chickens in a plots . The experimen was in a completely randomized bock design, in a 3 x 2 x 2 + 1 additional factorial. The treatments studied were: corn + soybean meal-based diets with normal levels of nutrients without enzymes and others 12 treatments with normal and reduced levels (3% in the growth phase and 5% in the final phase) of energy and/or protein, with addition of 0.5; 1.0 and 1.5 g/kg of diet of the multienzimatic complex. The parameters evaluated were weight gain, feed intake, feed conversion, european productive efficiency index, carcass yield and abdominal fat yield. The results showed better performance for those broiler fed diets suplemented with enzymes, wich shown increase of the weight gain and improvement in the feed conversion at 28 days old maily for diets with 1.0 g/kg of enzyme as well as for the european productive efficiency index. Therefore broilers at 42 days old , the addition of enzymes in the diets shown no effects on european productive efficiency index, carcass yield as well as the abdominal fat yield in the chickens.

Foram utilizados 819 pintos de corte, distribuídos em 13 tratamentos, com três repetições e 21 aves por parcela com delineamento inteiramente casualizado, em fatorial 3 x 2 x 2 + 1. Os tratamentos estudados foram: dietas à base de milho + farelo de soja com níveis normais de nutrientes sem enzimas e mais 12 tratamentos com níveis normais e reduzidos (3% na fase de crescimento e 5% na fase final) de energia e/ou proteína, com adição de 0,5, 1,0 e 1,5 g/kg de dieta do complexo multienzimático. A significância estatística foi avaliada pelo teste de Tukey. Os parâmetros avaliados foram: ganho de peso (GP), consumo de ração (CR), conversão alimentar (CA), índice europeu de eficiência produtiva (IEEP), rendimentos de carcaças (RC) em relação ao peso vivo e teores de gordura abdominal (GA). Pelos resultados, verificou-se melhoria no desempenho zootécnico das aves devido à aplicação de enzimas, constatado pelo aumento do GP e melhoria na CA aos 28 dias de idade, quando foi adicionado 1,0 g/kg de enzima na dieta, influenciando o IEEP. Aos 42 dias de idade, a adição de enzimas não influenciou o IEEP, os RC e nem os teores de GA dos frangos.Editora da Universidade Federal de Lavras2003-12-012015-04-30T13:32:56Z2015-04-30T13:32:56Z2015-04-30info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articletext/htmlhttp://www.scielo.br/scielo.php?script=sci_arttext&pid=S1413-70542003000600027TORRES, D.
