Abstract: This book discusses the factors which affect the heat produced by animals and man and the ways in which the energy of the organic components of their diets are used to support growth and reproduction. The general thermodynamic principles are considered in addition to the physical principles related to heat loss by radiation, convection, conduction and evaporation of water. Major parts of the book deal with the minimal or basal production of heat, with the heat produced during muscular work and as a result of physiological reactions to the climatic environment. The test is intended for undergraduates and postgraduates who are studying energy metabolism in the context of zoology, agriculture, ecology, or medicine.

Comparative Nutrition of Man and Domestic Animals, Volume I discusses practical phases in the evaluation of the nutrient requirements of man and his domesticated animals and the factors that modify these quanta. This book also covers various nutrients' biochemical nature, functions, and participation in the energy transactions of the body. Organized into 11 chapters, the book initially discusses the principles of the basal metabolism and the activity increment and their role in evaluating maintenance requirement of human and animal for energy. The subsequent chapter focuses on the maintenance requirement of protein under stress and non-stress conditions. Other chapters discuss nutrient requirements for maintenance, such as water and minerals. The book also examines the nutrient requirements for muscle activities, growth, senescence, reproduction, and lactation. A discussion on the storage of nutritive material, such as water, protein, minerals, vitamins, and energy, is included. This volume is an invaluable source for organic chemists, biochemists, animal physiologists, zoologists, and nutritionists.

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.

The Twelfth Annual Midwest Conference on Endocrinology and Metabolism continued the tradition of selecting a topic of inter est to a wide variety of scientists with interests in biology. The conference an "Hormones and Energy Metabolism" was dedicated appro priately to Dr. Samuel A. Brody, a leader in research in this field as described by Professor Johnson in this volume. A particular feature of these conferences has been the large proportion of time devoted to discussion of each paper and the pub lished proceedings have included edited transcripts of these dis cussions. Unfortunately, due to malfunction of the recording sys tem, major portians of the discussions were lost and, despite much effort, insufficient was salvageable tobe meaningful and helpful. Consequently, the editors decided to omit completely the discus sions except for a communication provided by Dr. Woodside. We again express our appreciation to the staff of Conferences and Short Courses, University of r~issouri-Columbia Extension Divi sion and especially to Dr. John Swanson who helped organize the multitude of administrative details; to ~lrs. Linda Bennett, CPS, for her continuing excellent efforts in typing the manuscripts for publication; and particularly to the sponsors, without whom there would have been no conference. Ralph R.
