AB Blood indicators are used as a tool to diagnose metabolicdisorders. The present work was conducted to study therelationships among blood indicators of lipomobilization andhepatic function in high-yielding dairy cows. Two groups ofHolstein cows were studied: 27 early lactation cows and 14mid lactation cows from four different herds with similarhusbandry characteristics in Galicia, Spain. Blood sampleswere obtained to measure beta-hydroxybutyrate (BHB),non-esterified fatty acids (NEFA), triglycerides (TG), andthe activity of aspartate transaminase (AST) andgamma-glutamyl transferase. Cows in early lactation hadhigher levels of BHB and NEFA than mid lactation cows.High lipomobilization (NEFA ＞ 400 μmol/L) was detectedin 67% and 7% of early lactation and mid lactation cows,respectively, while subclinical ketosis (BHB ＞ 1.2 mmol/L)was detected in 41% and 28% of the early lactation andlactation cows, respectively. TG concentrations were lowin all cows suffering subclinical ketosis and in 61% of thecows with high lipomobilization. During early lactation,30% of cows suffered hepatic lipidosis as detected bylevels of AST. Compromised hepatic function wasobserved in early lactation cows as shown by lowerconcentrations of glucose, total protein, and urea
