The transition period (last 3 weeks prepartum until 3 weeks postpartum) is the most critical stage in the lactation of dairy cow, characterized by lipid mobilization, proinflammatory state and insuline resistance during peripartum. The aim of this study was to evaluate the insuline-signaling pathway and certain proinflammatory factors in the liver and metabolic biomarkers in plasma during the transition period in cows with different body condition score (BCS). Sixteen grazing dairy cows from a commercial dairy farm were classified according to BCS using the 5-point scale as high BCS (HBCS, >3.5, n=8) and low BCS (LBCS,
