Title: CHANGES OF STABLE ISOTOPES CARBON-13 AND NITROGEN-15 IN DIFFERENT TISSUES OF CATTLE
Abstract: Stable isotope analysis is a potential tool for tracing food origin.The stable carbon and nitrogen isotope composition in different tissues of two varieties of cattle under the same culture condition were investigated.δ(~(13)C) and δ~(15)N values of different defatted muscle and crude fat,cattle tail hair,blood,liver and feed were determined by isotope ratio mass spectrometry,and statistical analysis was carried out.The results showed that stable isotopes of carbon and nitrogen composition was not affected by cattle variety;the δ(~(13)C) values between different defatted muscle,blood,liver and cattle hair were not significantly different,but δ~(15)N value in the liver was much higher than other muscle and the δ(~(13)C) values didn't show difference among all the crude fat samples.So these results indicated that isotope fractionation in the various tissue was discrepant.
