Regulation of Feed Intake in Dairy Cows. I. Change in Importance of Physical and Physiological Factors with Increasing Digestibility
TLDR
It was concluded that physical and physiological factors regulating feed intake change in importance with increasing digestibility, and intake appeared to be dependent on metabolic size, production, and digestibility at higher digestibilities.About:

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.

Regulation of Forage Intake
TL;DR: Although intake is more important than digestibility in assessing forage quality, progress in understanding the basic factors that affect intake has been hampered by the inability to measure it accurately and to separate the influences of animal and diet on intake.

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.

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.

Urges to eat and drink in rats.
TL;DR: The investigation was designed to ascertain how an animal solves conflicts, and practices priorities, in its bodily maintenance, by forcing into the metabolism of an animal considerable quantities of various ingested materials that would ordinarily be refused.

The regulation of food intake by sheep
TL;DR: A series of experiments with adult sheep were carried out in an attempt to place on a quantitative basis the generalisation that the voluntary food intake of ruminants increases with the quality of the fodder they are given.

Studies of the Energy Requirements of Chickens 1. The Effect of Dietary Energy Level on Growth and Feed Comsumption
F. W. Hill,L. M. Dansky +1 more
TL;DR: The energy requirement of growing chicks has been studied in two widely different ways: Mitchell, Card and Hamilton as discussed by the authors, who estimated the net energy requirements for maintenance and growth from the determination of basal metabolic rate and changes in body composition, and Robertson, Miller and Heuser (1948), and Panda and Combs (1950).
