Studies in the Agricultural and Food Sciences: Energy Metabolism is a compilation of works on the energy metabolism in animals, especially animals of agricultural importance. The book is written by authoritative workers in the field and is divided into six parts; each chapter is based on a selected paper presented at the Eighth Symposium on Energy Metabolism held at Cambridge in September 1979. The text discusses feed evaluation; use of energy for maintenance and growth; and simulation models for energy exchange and growth. The book also covers the comparative aspects of energy metabolism; use of energy in production and lactation; and metabolic responses in the growing animal. The monograph is recommended for those who plan to study about energy metabolism of farm animals and its relationship with certain biological processes. The book will also appeal to those who develop feeds and methods that can help improve energy metabolism of farm animals.
