This volume investigates the fundamental nutritional requirements and metabolic processes of livestock species critical to agricultural production. Sir David Cuthbertson, a prominent expert in nutritional science, compiles research to establish a comprehensive framework for understanding how dietary intake influences the growth, health, and productivity of farm animals. The text synthesizes physiological data to provide a standardized reference for agricultural researchers and practitioners.

Experts recognize this work as a foundational reference text within the International Encyclopaedia of Food and Nutrition series. Readers frequently note the technical density of the prose, which is intended for an audience of agricultural scientists and advanced students.
