Suplementação de enzimas amilase, fitase e protease para codornas japonesas em postura

Abstract

O objetivo deste trabalho foi avaliar os efeitos da suplementação das enzimas amilase, fitase e protease de formas isoladas e em associação, em dietas para codornas japonesas em postura. Foram utilizadas 300 codornas, distribuídas em um delineamento inteiramente ao acaso, com cinco tratamentos e seis repetições de dez aves por unidade experimental. Os tratamentos foram: uma dieta controle e dietas formuladas com a suplementação de 300 ppm de amilase, 300 ppm de protease e 500 FTU/kg de fitase e com a associação de enzimas. Nas fórmulas com inclusão de enzimas houve aplicação de redução na exigência nutricional de um ou mais dos seguintes componentes: proteína, aminoácidos digestíveis, energia, cálcio e fósforo, valorizando o uso das enzimas. As avaliações foram realizadas em quatro períodos de 21 dias cada. Foram avaliados desempenho (produção média de ovos, consumo de ração, peso médio dos ovos e conversão alimentar), qualidade dos ovos (proporção dos constituintes do ovo e peso específico dos ovos) e digestibilidade dos nutrientes da ração (coeficiente de metabolizabilidade aparente da matéria seca e da proteína bruta). Não houve efeito significativo dos tratamentos nas variáveis analisadas (P>0,05), indicando que as enzimas têm efeito benéfico, isoladamente ou em associação, mantendo o desempenho e qualidade dos ovos de codornas japonesas.
