Whole body oxidative metabolism in dairy cows with a different liver fat content in early lactation
Chapter
Abstract
During the transition from late pregnancy to early lactation, high-yielding dairy cows mobilize large amounts of adipose tissue resulting in increased plasma concentrations of non-esterified fatty acids (NEFA). NEFA are mostly oxidized to CO2 whereas at excessive concentrations, NEFA are re-esterified to form triacylglycerides leading to the development of fatty liver. Thus, the capacity for fatty acid oxidation - among others - determines the fat load of the liver. We hypothesized that whole-body fat oxidation adapts to the extent of fat mobilization during early lactation.
