Turnover of carbon in blood and plasma, growth stages and posture, japanese quails (Coturnix coturnix japonica)

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.
