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

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