The aim of this study was to evaluate the metabolic profile of protein, energy and enzyme in crossbred dairy cows with low body condition score (BCS) in the peripartum period. Blood samples were collected from 36 animals with 2.6±0.5 BCS, eutocia, physiological postpartum and without any treatment, on following days: one week before calving, calving and 7, 14, 21, 28 and 43 days in milk (DIM). It was evaluated serum total protein, albumin and globulins for protein profile; AST, ALT, GGT and alkaline phosphatase for mineral profile; nonesterified fatty acids (NEFA), β-hydroxybutyrate (BHBA), triglycerides, cholesterol and lipoproteins (VLDL, HDL and LDL) for energy profile. Crossbred dairy cows had hypoproteinemia, hypoalbuminemia, hypocholesterolemia and increased that both enzymes AST and GGT at the precalving. There were lipolysis and hypoglobulinemia at parturition. It was concluded that crossbred dairy cows with low BCS have negative energy balance, hypoproteinemia with hypoalbuminemia and hepatic injury in the peripartum. This condition is restored at 30 DIM, but there is no recovery of the body condition by the end of puerperium.
