Popis:	Background: Use of novel biomarkers is the need of hour for prediction and early diagnosis of bovine production diseases such as hepatic lipidosis (HL). Liver ultrasonography and estimation of liver specific enzymes activities have been successfully used for diagnosis of HL. However, use of inflammatory mediator like tumor necrosis factor-á (TNF–á) or acute phase proteins (APPs) like C reactive protein (CRP), serum amyloid A (SAA) and haptoglobin (Hp) as biomarkers of HL has not been elucidated. The present study was therefore designed to evaluate liver ultrasonography and serum APPs concentrations as early predictive biomarkers of bovine HL. Methods: This study included one hundred one (101) multiparous crossbred cows in advanced pregnancy from dairy farm in Punjab, India. The cows were grouped according to their transition stage i.e., Far off dry (FOD), close up dry (CUD) and Fresh (F). Liver ultrasonography along with hemato-biochemical analysis and estimation of acute phase proteins was carried out during different stages of transition period. Result: This study included 101 cows, of which 71 (70.3%) had ultrasonographic features of normal liver and 30 (29.7%) had ultrasonographic features of HL (Grade I, 10 cows; Grade II, 12 cows; Grade III, 8 cows). Cows with HL had significantly lower levels of hemoglobin (Hb), packed cell volume (PCV), total erythrocyte count (TEC), total plasma protein (TPP), glucose, total calcium (Ca) and zinc (Zn) and significantly higher levels of plasma urea nitrogen (PUN), non-esterified fatty acid (NEFA), beta hydroxyl butyric acid (BHBA), alkaline phosphatase (ALP), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT), glutamate dehydrogenase (GDH), lactate dehydrogenase (LDH), TNF–á, CRP, SAA and Hp compared to the negative controls. The APPs, liver ultrasonography, liver enzymes along with NEFA and BHBA could be used as biomarkers for prediction and early diagnosis of HL in cows.
