If nutritional status is not limited (no nutrient deficiencies), the rate of substrate catabolism vs. anabolism is regulated by the

In the Net Energy Scheme, energy losses between Metabolizable Energy and Net Energy are defined as heat increment, ie., the heat generated by digestion and nutrient metabolism.  Major factors that influence heat increment____ 

The anaerobic environment of the rumen results in

As a coenzyme in the pyruvate dehydrogenase enzyme complex, thiamin is involved in reactions that remove CO2 from organic acids and transfer aldehydes to other compounds to form complexes such as acetyl coenzyme A. These reactions are
