Aimed to evaluate the benefits of adding the cell wall of Saccharomyces cerevisiae (CWSC) and its best level in the diet on the performance and quality of eggs produced by Japanese quail (Coturnix coturnix japonica), during the production phase. 400 Japanese quails, were distributed in a complete random design, with five treatments and 10 replicates with 8 birds each. It was used five diets with different levels of cell wall of S. cerevisiae (0 kg/t; 0.5kg/t; 1.0kg/t; 1.5kg/t; 2.0kg/t). To analyze the performance of birds and egg quality, the variables evaluated were: feed intake, egg production, egg weight, egg mass, feed conversion per dozen of eggs produced, feed conversion per mass of eggs produced, viability, percentage of the yolk, percentage of the albumen, percentage of the shell and shell thickness. Egg weight, percentage of yolk and percentage of albumen were not influenced by the inclusion of cell wall of S. cerevisiae in the diet of Japanese quails. The increasing levels of cell wall of S. cerevisiae to the level of 1.5kg/t in the diet improved production, feed conversion per dozen, feed conversion per mass and shell quality of eggs produced by Japanese quail during the production phase.
