Performance of laying quails fed diets containing sugar cane yeast

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.
