Polyphenols are increasingly used in animal feeding in order to delay the lipid oxidation of meat and, eventually, increase the deposition of beneficial compounds for the consumer. Interestingly, the biological activities of polyphenols go beyond their widely known antioxidant capacity, being able to modify several physiological pathways. Therefore, the aim of this study was to evaluate the effect of grazing on sainfoin or alfalfa â legumes rich in polyphenols but with different amount of proanthocyanidins â during lactation in the metabolite profile of lambsâ muscle, by using HPLC-ESI-QTOF MS analysis. Thirteen metabolites were modified in the polar fraction of muscle in Sainfoin lambs, as compared with Alfalfa lambs (P<0.05). Among them, 6 were related to fat metabolic fate (biliary acids, fatty acids, etc.), showing the wide variety of processed affected by polyphenols. Further studies should evaluate the effect of these strategies on the whole metabolome of lamb muscle, in particular considering their health implications.
