The study aimed to evaluate the turnover of 13C in the blood and plasma of Japanese quail using the technique of stable isotopes to obtain the level of isotopic equilibrium that will be the foundation for studies of traceability. A total of 300 birds during the experimental period of 1-42 and 49-97 days of age. The first phase of the treatments consisted of diets based on rice (C3), with or without meat and beef bones and a diet based on corn (C4). This was first examined the turnover signal farm matrix isotope-based diets based diets C4 to C3, as well as isotopic differences of diets with or without animal meal In the second stage there was a substitution of diets, or C4 treatment of the first stage passes to consume C3-based diet than before treatment and diet consumed C3 to C4 diet. To determine the turnover rate and the estimated percentage of participation of flour in the composition of the collected material was used isotope dilution model using δ13C values. A comparison of the half-lives of blood and plasma from the first phase discloses the enrichment of dietary δ 13C, in the second phase was observed after incorporation speeds exchange diets.
