The carbon isotope composition of cattle tissues is compared, and the effect which cattle species, feeds on them is studied. The aim of the paper was providing the theory basis and methodology foundation which use a stable isotope analysis to trace cattle origin. 【Method】The δ13C values of cattle hair, de-fatted muscle and muscle crude fat were tested using isotope ratio mass spectrometry (IRMS) MAT253, and the correlations between them were analyzed. 【Result】The tissues δ13C values decreased from hairdefatted musclemuscle crude fat, and the pairs δ13C values between them were significantly correlated. Diet composition hada large effect on stable carbon isotope composition of cattle tissues. The stable carbon isotope compositions of cattle tissues mainly depended on staple feeds. Concentrates and additives had less effect on them.【Conclusion】The δ13C value was an important indicator which showed cattle diets and traced cattle origin.Read More
