Journal ArticleDOI
Methods for dietary fiber, neutral detergent fiber, and nonstarch polysaccharides in relation to animal nutrition.
TL;DR: In addition to NDF, new improved methods for total dietary fiber and nonstarch polysaccharides including pectin and beta-glucans now are available and are also of interest in rumen fermentation.

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.

Voluntary food intake and diet selection in farm animals.
TL;DR: Feeding behaviour feedback signals ruminant gastrointestinal tract metabolites and hormones central nervous control integrative theories of food intake control growth and fattening reproduction and lactation diet digestability and concentration of available energy specific nutrients affecting intake.
Journal ArticleDOI
Characteristics of plant cell walls affecting intake and digestibility of forages by ruminants.
TL;DR: A simple model of cell-wall digestion and passage in which ruminal fill is a function of rates of digestion and Passage, as well as the indigestible fraction of thecell-wall indicates that cell- wall concentration and rate of passage are the most critical parameters determining ruminalFill.

Journal ArticleDOI
Proposal to use time spent chewing as an index of the extent to which diets for ruminants possess the physical property of fibrousness characteristic of roughages.
TL;DR: Exerssion of the roughage index as total time spent chewing per kg dietary dry matter largely eliminates differences resulting from variation in the amount of food consumed, and Differences resulting from the time of access to the food.

Forage quality and rumination time in cattle.
J.G. Welch,A.M. Smith +1 more
TL;DR: Three experiments investigated how forages of different chemical composition affect rumination time of cattle, using four dairy heifers and two dairy steers in Experiment I and three single reversal designs in Experiments II and III.

The effect of specific gravity and size on the mean time of retention of inert particles in the alimentary tract of the cow.
R. C. Campling,M. Freer +1 more
TL;DR: Campling et al. as mentioned in this paper examined the effect of the specific gravity of inert particles on their mean retention time in the alimentary tract of the cow, and have given particular attention to the relative time the particles were retained in the reticulo-rumen and in the remainder of the aliment tract.

Density and Size as Factors Affecting Passage Rate of Ingesta in the Bovine and Human Digestive Tracts
K.W. King,W.E.C. Moore +1 more
TL;DR: The effect of density and size of the passage rate of particles through the digestive tract of cattle and humans has been estimated, using inert plastic particles as discussed by the authors, and the significance of this equation and of a pronounced shoulder in the excretion curve is discussed.
