TLDR
In this paper, two complete energy balance trials were performed with lactating and dry cows consuming 40% of the dry matter from concentrate and 60% from corn silage, and two concentrate mixtures were given so that the total diets contained 16.0 and 11.2% crude protein.About:

Methane Production in Dairy Cows
P.W. Moe,H.F. Tyrrell +1 more
TL;DR: The relationship among diet composition, intake, and methane production was investigated with data during 404 total energy balance trials with Holstein cows as discussed by the authors, and the most useful predictor of total methane productin was amounts of soluble residue, hemicellulose, and cellulose that apparently were digested.

Protein-Energy Interrelationships in Dairy Cows
TL;DR: In dairy cows two distinct and important aspects of the interrelationship between protein and energy-yielding nutrients can be identified; that changing "protein" supply to tissues can alter the pattern and efficiency of absorbed nutrient use and that at high levels of feeding rumen microbial demand for nitrogen per unit fermentable organic matter is high.

Effect of Intake on Digestive Efficiency

TL;DR: More research on factors affecting digestive efficiency of the structural carbohydrate of plant cell walls is needed to develop a precise method for predicting total ration nutritive value of diets fed to the high producing dairy cow.

A mechanistic model of whole-tract digestion and methanogenesis in the lactating dairy cow: model development, evaluation, and application.
TL;DR: In this article, a dynamic mechanistic model of the whole rumen function was proposed to predict methane production over a range of dietary inputs to develop novel dietary regimes for the limitation of feed energy loss to methane.

TL;DR: It is concluded that feed intake is the main determinant of total CH4 production and that CH4-E/GE is negatively related to feeding level and dietary fat concentration and positively to diet digestibility, whereas dietary carbohydrate composition has only minor effects.

Energetics of Body Tissue Mobilization
P.W. Moe,H.F. Tyrrell,W.P. Flatt +2 more
TL;DR: It appears unrealistic to relate tissue energy changes to live weight change without some consideration being given to the change in rumen fill, but data from this laboratory suggest that milk may be produced from body tissue reserves with an efficiency of 82 to 84% and that theBody tissue reserves may be replenished in late lactation by deposition of body tissue with a efficiency equal to or exceeding that of milk production.

Net Energy Value of Feeds for Lactation
P.W. Moe,W.P. Flatt,H.F. Tyrell +2 more
TL;DR: In this article, the authors summarized 543 energy balance trials with lactating cows to partition the energy required by cows into maintenance and production components and to determine the influence of energy source on the efficiency with which dietary energy is used for milk production.
