The processing of the guava fruit has generated residues that can be used in animal feed, in order not only to reduce feed production costs, but also to give destinations to industry by-products. This study aimed to evaluate the effect of including guava meal (Psidium guajava L.) in european quail diets (Coturnix coturnix coturnix) on egg quality, in the first laying cycle. For this, an experiment was carried out at the Rural Federal University of Pernambuco / Academic Unit of Serra Talhada (UFRPE / UAST), in the municipality of Serra Talhada – semiarid region of Pernambuco, Brazil. European quails were used in wire cages arranged on pyramidal stands. The treatments consisted of a reference diet (based on corn and soybean meal, without the inclusion of guava seed meal) and four levels of inclusion of guava seed meal (2, 4, 6 and 8%) to the detriment of inclusion of corn in diets. It was observed that there was no significant difference between the levels of guava bran, included in the european quail diets in terms of: albumen height, yolk height, shell thickness, yolk color and egg weight. Thus, it was concluded that guava bran can be included in diets for european quails in production at the expense of the inclusion of corn without affecting the quality of eggs.
