Metabolizable energy of roughage in Taiwan
Small Ruminant Research, 2000The fixed metabolizable energy (ME) values from the NRC do not represent the true ME values of the various feedstuff used in livestock rations. Therefore, a rapid and effective method for evaluating the ME value of forage crops is required for proper ration formulation to improve production efficiency.

Heritability of beef cow metabolizable energy for maintenance
Journal of Animal Science, 2023Abstract Most of the metabolizable energy that a cow uses during a production year is for maintenance; however, less is known about the heritability of maintenance compared to other traits that can be measured directly. Feed intake is a heritable trait in the mature cow and most of the feed consumed is used for maintenance.

Metabolizable energy of macronutrients
The American Journal of Clinical Nutrition, 1995I describe recent advances in assessing the amount of energy available from diets of varied composition. Empirical models of food energy prediction have grown in preference to factorial models over the past 20 y and knowledge of the quantitative aspects of energy salvage in the colon have modified our thoughts on how to best calculate food energy ...
