Postingestive Feedback as an Elementary Determinant of Food Preference and Intake in Ruminants
TLDR
From an evolutionary standpoint, mechanisms that enable animals to experience feedback, sensations such as satiety and malaise, should be highly correlated with nutritional well being, toxicosis, and nutritional deficiencies, which are directly related with survival and reproduction.

TLDR
The subtle ways in which aversions diminish preference and cause animals to eat a variety of foods are discussed, one which encompasses the avoidance of toxins and the acquisition of nutrients.

Interactions between woody plants and browsing mammals mediated by secondary metabolites
Mammals must overcome several challenges to exploit woody plants; these include variation among plant species, individuals, growth stages, and parts in their nutritional value and mechanical and…

Experience Influences Diet Mixing by Herbivores: Implications for Plant Biochemical Diversity
TLDR
How sheep learned about their foraging environment was crucial to the development of their dietary habits, and that experience with foods that contained plant secondary metabolites (PSM) markedly enhanced their use of PSM-containing foods, even when familiar, nutritious alternatives were available ad libitum.

The Physics of Foraging
We relate findings in physics to biological processes like foraging. As in physics, the critical attribute of any individual (elementary particle or animal) is the fact that the dynamics of its…
Influence of free-choice vs mixed-ration diets on food intake and performance of fattening calves.
TLDR
Animals can more efficiently meet their individual needs for macronutrients when offered a choice among dietary ingredients than when constrained to a single diet, even if it is nutritionally balanced.
