Resumo: | Mannan oligosaccharides, as an alternative to an-tibiotics, show promising results related to bird perfor-mance, immunity stimulus and improvement of intestinal mucosa. Enzyme inclusion in diets containing mannan oli-gosaccharides could improve these results. Poultry diets consist of corn and soybean meal, and approximately 30% of the phosphorus (P) in these ingredients is bound to phytic acid. Phytase is capable of release not only the P but also other nutrients that can be better used by the birds while corn is relatively free of viscosous nonstarch poly-saccharides (NSP), soybean has about 20% of NSP, whose digestibility is almost null. NSP`s insoluble component of corn and soybean encapsulate nutrients and are responsive to exogenous enzymes. Negative environmental and nutri-tional consequences of dietary phytic acid are reduced by phytase inclusion in monogastric diets. Additionally, the enzymatic complex supplementation improves the nutri-tional value of feedstuffs through higher digestibility in birds. Finally, the use of exogenous enzymes allows re-duction in feed costs. KEY-WORDS: Animal nutrition, enzymatic supplementation, prebiotic. |

Os mananoligossacarídeos, como alternativa aos antibióticos, têm apresentado resultados promissores no que se refere tanto ao desempenho das aves quanto ao estímulo da imunidade e à melhora da mucosa intestinal. A inclusão de enzimas nas dietas contendo mananoligossacarídeos poderia melhorar ainda mais esses resultados. As dietas para aves são compostas de milho e farelo de soja, principalmente, e cerca de 30% do fósforo (P) desses in-gredientes estão ligados ao ácido fítico. A fitase libera não só o P, mas também outros nutrientes para que sejam me-lhor utilizados pelas aves. O milho é relativamente isento de polissacarídeos não-amiláceos (PNAs) viscosos e a soja apresenta cerca de 20% de PNAs, com digestibilidade praticamente nula. Os componentes insolúveis dos PNAs do milho e da soja encapsulam nutrientes e são responsi-vos às enzimas exógenas. As conseqüências ambientais e nutricionais negativas do ácido fítico dietético são amenizadas pela inclusão de fitase na dieta dos monogástricos. Além disso, a adição de complexos enzimáticos incre-menta o valor nutritivo dos alimentos ao complementar a produção de enzimas endógenas nas aves e melhorar a disponibilidade dos nutrientes. Por fim, a suplementação enzimática das dietas apresenta vantagens econômicas, pois reduz o custo das rações. PALAVRAS-CHAVES: Nutrição animal, prebiótico, suplementação enzimática.
