Abstract
Este experimento foi conduzido para avaliar o efeito da inclusão de levedura de cana-de-açúcar (Saccharomyces cerevisiae) na ração sobre o desempenho de codornas japonesas em postura. Foram utilizadas 240 aves distribuídas em um delineamento experimental inteiramente casualizado com seis tratamentos (0, 3, 6, 9, 12, 15% de inclusão), contendo oito repetições de cinco aves. Os níveis de inclusão de levedura não afetaram a percentagem de postura nem a massa de ovo; entretanto, o consumo de ração e o peso dos ovos aumentaram linearmente com o acréscimo de levedura nas rações, enquanto a conversão alimentar piorou. Não foram observadas diferenças significativas para percentagem de albúmem e percentagem de gema, mas houve efeito quadrático sobre a percentagem de casca e a coloração da gema. A inclusão de levedura nas rações de codorna em postura deve ser de no máximo 11%.
This experiment was carried out to evaluate the effects of diets containing different levels of sugar cane yeast (Saccharomyces cerevisiae) on production performance of laying quails. Two hundred and forty birds were distributed in a completely randomized design with six treatments (0, 3, 6, 9, 12 e 15% of sugar cane yeast) and eight replications of five quails. Egg production and egg mass were not affected by treatments. Feed intake and egg weight increased linearly as the level of sugar cane yeast increased in diets, while feed conversion decreased. Percentages of egg albumen and egg yolk were not affected by diets. However a quadratic effect was found for shell percentage and egg yolk color. The sugar cane yeast can be included up to 11% in diets for laying quails.
