The objective was to determine optimal thresholds of blood variables that are associated withliver lipid and glycogen content in dairy cows. Liver specimens of 15 Holstein dairy cows weretaken 2 weeks postpartum (PP) and used for determination of lipid and glycogen content,respectively. Blood samples were collected weekly, starting from week 2 antepartum (AP) up toweek 2 PP. Selected blood parameters and body condition scoring (BCS) were evaluatedthrough receiver operating characteristic curve analysis as indication of fat and glycogen con-tent in the liver. Postpartal low liver glycogen content (mode20%, stereological quantification of fat content in the liver tissue samples) can be indi-cated if values are higher than 3.5 for BCS at week 2 AP. Optimal time for indicating both lowliver glycogen/high fat content is 1 week PP, with LDLcut off point set at 0.88 mmol/L. Established cut off values in this study can be used forindication of fat and glycogen content in the liver of dairy cows.
