Nutritional regulation of milk fat synthesis.
Certain diets cause a marked reduction in milk fat production in ruminants. Commonly referred to as milk fat depression (MFD), the mechanism involves an interrelationship between rumen microbial processes and tissue metabolism. Numerous theories to explain this interrelationship have been proposed and investigations offer little support for theories that are based on a limitation in the supply ...
متن کاملRecent advances in the regulation of milk fat synthesis.
In addition to its economic value, milk fat is responsible for many of milk's characteristics and can be markedly affected by diet. Diet-induced milk fat depression (MFD) was first described over a century ago and remains a common problem observed under both intensive and extensive management. The biohydrogenation theory established that MFD is caused by an inhibition of mammary synthesis of mi...
متن کاملRegulation of Milk Fat Synthesis by Dietary Fatty Acids
Title of Document: REGULATION OF MILK FAT SYNTHESIS BY DIETARY FATTY ACIDS ANIL KUMAR G. KADEGOWDA PhD. 2008 Directed By: Professor, Dr. RICHARD ERDMAN, Dept. of Animal and AvianSciences, UMCP. The objectives of this thesis research were to determine the molecular mechanisms by which dietary fatty acids (FA) regulate lipogenic gene expression and milk fat synthesis. Principal component and mult...
متن کاملRole of K on Rumen Fermentation and Milk Fat Synthesis
Diet-induced milk fat depression (MFD) continues to have major economic impact in the dairy industry and a priority for finding solutions. Current thinking links MFD with the formation of bioactive trans fatty acid intermediates produced from biohydrogenation of unsaturated fatty acids by the rumen microbial population. The most potent biohydrogenation intermediates linked to MFD include severa...
متن کاملManaging Milk Fat Depression
Milk fat concentration is variable within and between farms and is modified by genetics, season of the year, and physiological state, but is especially responsive to diet. Synthesis of milk fat is an energy demanding process, but also represents a significant portion of the economic and nutritional value of dairy products. First described over one and a half centuries ago, diet-induced milk fat...
