Carbon isotopic ratio of lipid fraction to trace fractionation processes in cull cows organism and to discriminate between different feeding regimes

In the present work, quantification of lipids and carbon isotopic ratio (δ13C) diet, rumen, liver meat cows fed on different diets (based either C3 or C4 plants) are provided. The δ13C four compartments had trends in two diets, which could give information about fractionation processes factors influencing metabolic path regimes. resulted to be statistically for groups C4, can therefore a suitable tool discriminate between groups.
