Patterns of Energy Output During Reproduction in Carnivores
TL;DR: Female reproduction involves substantial commitment of nutritional resources: for example, the energy required by a female ungulate to rear a single offspring from conception to weaning is similar to maintenance energy needs for approximately 100–150 days.

Urinary excretion of allantoin and allantoin precursors by sheep after different rates of purine infusion into the duodenum
TL;DR: Results show urinary allantoin to be a useful index to estimate duodenal input of purines when animals are fed close to or above their energy maintenance requirements.

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.

Effect of the tropical forage calliandra on microbial protein synthesis and ecology in the rumen.

Toward a new theory of feed intake regulation in ruminants
TL;DR: In this paper, the authors present a new theory that feed consumption creates both benefits to the animal (in a non-reproducing animal the intake of net energy for maintenance and gain) and costs (the total oxygen consumption of the animal).
