Tresholds of blood variables obtained by receiver operating characteristic analysis for indication of fat and glycogen content in the liver of postpartum dairy cowsPodpečan, Ožbalt (Avtor) Zrimšek, Petra (Avtor) Mrkun, Janko (Avtor) Goličnik, Marko (Avtor) Radovanović, Anita (Avtor) Jovanović, Ljubomir (Avtor) Vujanac, Ivan (Avtor) Prodanović, Radiša (Avtor) Kirovski, Danijela (Avtor) cattle - metabolismliver - physiologyadipose tissuepostpartum periodbovine liverfatglycogenindicationThe 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.20202020-08-14 10:12:38Članek v reviji118029sl
