Novel Mechanisms Involved With Lipid Metabolism In Adipose Tissue Of Dairy Cows, Dawn Koltes

Graduate Theses and Dissertations

Proper lipid metabolism is essential to the maintenance of milk production and fitness in the modern dairy cow. Little is known about the regulation of lipid metabolism in adipose tissue in dairy cattle, including the roles of adipokines and lipid droplet associated proteins. Therefore, the objectives of this study were to characterized changes in transcript abundances of adipokines during three different energy altering models, and lipid droplet associated proteins throughout the transition period and with leptin induced lipolysis. Transcript abundances of leptin decreased during feed restriction, while angiopoietin like protein 4 (ANGPTL4) increased during early lactation, feed restriction, and following ...
