Abstract

The aim of this study was to investigate the relationship between the parameters of lipid metabolism in plasma (non esterified fatty acids, β-hydroxy-butyrate, total cholesterol and triglyceride) and in liver (total lipid and triglyceride) of high producing dairy cows during the periparturient period. The data were obtained from two dairy herds with high lactation performance (over 9000 kg/lactation). Liver and blood samples were taken from 25 days before calving until 60th day of lactation. Plasma non esterified fatty acid level showed a positive correlation with plasma β-hydroxy-butyrate level and total lipid and triglyceride concentration. Plasma non esterified fatty acid to total cholesterol ratio positively correlated with β-hydroxy-butyrate level and total lipid and triglyceride content of liver (correlation coefficients: 0.618; 0.698; 0.691). The understanding of correlations between the metabolites of lipid metabolism provides the opportunity to develop a regression equation between plasma values and liver fat content. This regression and regular, representative metabolic profiling may serve as a simple and economical tool in identification of subclinical liver lipidosis.
