On day 20 of lactation, treatment significantly increased plasma cholesterol, folate and α-tocopherol and lowered NEFA, with a tendency for increased glucose and choline phospholipids, and reduced β-hydroxybutyrate. These differences indicate improved lipid and methyl group metabolisms. Milk production tended to be increased. RPC supplementation seems useful for optimizing the metabolic profile of transition dairy cows. AU - Pinotti, L. AU - Campagnoli, A. AU - Sangalli, L. AU - Rebucci, R. AU - Dell’Orto, V.
