A Nutritional Explanation for Body-Size Patterns of Ruminant and Nonruminant Herbivores
M. W. Demment,P.J. Van Soest +1 more
TL;DR: Calculations suggest that sufficient intake of a high-fiber diet cannot be maintained to provide the energy necessary to support larger body sizes, and changing body size is postulated as a mechanism for differentiating the feeding requirements of herbivores.
A nutritional explanation for body-size patterns of
TL;DR: In this article, the relationship between body size and digestive capacity is used in conjunction with a relationship between abundance and quality of plant food to discuss the relative efficiencies of ruminant and nonruminant digestion at different body sizes.

A theoretically-based model for predicting total digestible nutrient values of forages and concentrates
TL;DR: In this article, a model using concentrations of neutral detergent fiber (NDF), lignin, crude protein (CP), ash, fatty acids or ether extract, acid and neutral detergents insoluble crude protein, was developed for predicting total digestible nutrients (TDN) of feeds.
Journal ArticleDOI
Predicting intake and digestibility using mathematical models of ruminal function.
TL;DR: Steady-state models indicate fractional rates of digestion and passage can be used to define ideal nutritive entities and predict digestibility over a range of kinetic characteristics.

Invited review: Enteric methane in dairy cattle production: Quantifying the opportunities and impact of reducing emissions
TL;DR: The objectives of this review are to evaluate options that have been demonstrated to mitigate enteric CH4 emissions per unit of ECM (CH4/ECM) from dairy cattle on a quantitative basis and in a sustained manner and to integrate approaches in genetics, feeding and nutrition, physiology, and health to emphasize why herd productivity, not individual animal productivity, is important to environmental sustainability.

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.

Effect of level of intake on digestibility of dietary energy by high-producing cows.
P.W. Moe,J. T. Reid,H.F. Tyrrell +2 more
TL;DR: It is suggested that the dietary energy requirements of a 1,400-lb cow in body energy equilibrium increase per unit of milk produced as the milk output or feed input per day increases.

Net Energy Value for Lactation of a High and Low Concentrate Ration Containing Corn Silage
H.F. Tyrrell,P.W. Moe +1 more
TL;DR: In this paper, corn silage and either 30 or 60% of the dry matter from concentrate were fed to Holstein cows in amounts calculated to minimize body tissue change, and complete energy balance measurements were made at 6-week intervals throughout the lactation cycle.
