TLDR
In this article, the authors evaluated 40 rations with varying digestibility and density and found that fill limited intake of these sheep when the digestible energy of the rations was less than 2.5 kcal/g, whereas above this level energy intake was regulated.About:

Toward a new theory of feed intake regulation in ruminants 1. Causes of differences in voluntary feed intake: critique of current views.
TL;DR: It is concluded that the framework offers an incomplete and unsatisfactory explanation for the observed variation in intake and doubt is expressed as to the validity of the basic assumption that feeding behaviour aims at achieving a maximum nutrient intake.

The feeding strategies of two freshwater gastropods, Ancylus fluviatilis Müll. and Planorbis contortus Linn. (Pulmonata), in terms of ingestion rates and absorption efficiencies.
TL;DR: Radiotracer and gravimetric techniques were used to investigate the effects of starvation, temperature, body size and food quality on both the ingestion rates and absorption efficiencies of A. fluviatilis and P. contortus and found that snails showed a considerable potential for adaptation.

Factors affecting the voluntary intake of food by sheep
TL;DR: Sheep equipped with rumen and abomasal cannulas were given ad lib.

Regulation of fat intake in the absence of flavour signalling
TL;DR: The results support the existence of a gut–brain dopamine axis that functions as a flavour‐independent central sensor of fat calories and support the hedonic orosensory properties of fats.

Dry Matter and Energy Intake in Relation to Digestibility in White-Tailed Deer
TL;DR: The data indieate that these animals were able to maintain a constant energy balanee, elose to the maintenanee requirements of fawns, by adjusting dry matter intake when fed diets of medium to high digestibility (DE > SO pereent ), and the threshold at which digestive traet fill began to limit the dry matter and energy intake of these animals.

Regulation of Feed Intake in Dairy Cows. I. Change in Importance of Physical and Physiological Factors with Increasing Digestibility
TL;DR: 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.

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.
