The aim of this paper was to trace the presence of meals from animal origin, in diets for broilers with or without yeast and wheat meal, through the analysis of breast muscle, by using carbon and nitrogen stable isotope techniques. Two hundred ten male chicks (Cobb) one‑day old were randomly distributed to seven treatments (30 birds each), with a control diet (exclusively vegetal), and six diets containing meat and bone meal or poultry offal meal, with or without yeast and wheat meal in their compositions. At 42 days ofage, four broilers randomly chosen, by treatment were slaughtered, and their breast muscles were collected for isotopic ratio analysis. The isotopic results were analyzed by multivariate statistical analysis of variance. The treatments differed from the control and the inclusion of meals of animal origin was identified by stable isotope techniques, even when there was yeast or wheat meal included in the diet.
