Book Description
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.

Book Description
Animal production systems have changed dramatically over the last two decades. Knowledge of energy metabolism and environmental physio logy has increased as appears from many textbooks on these disciplines. The contents of the symposia on energy metabolism of farm animals show this and they have initially focussed on feed evaluation and later on com parative aspects of energy metabolism. They show part of the progress being made. Application of knowledge of energy metabolism for animals has a long history since Lavoisier. In addition to this, studies about the environ mental requirements of animals have shown that we are still far from ac curate assessment of these requirements in terms of nutrients and ener gy. I n model studies on energy metabolism researchers have recognized the interaction between the environment and the energy requirements of animals. Estimation of energy requirements has been done in physiolo gical, physical and behavioural studies. The impact of conditions as en countered by animals in various production systems has been approached from different viewpoints related to these different disciplines. In addi tion, various kinds of infections (bacterial, parasitic: subclinical, clini cal) have been evaluated only recently with regard to their effect on pro tein and/or energy metabolism and thus on production. People working in the field of feed evaluation have defined how che mical and physical properties of nutrition infiuence energy to be derived for maintenance and production.

Book Description
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.

Book Description
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.

Book Description
An Outline of Energy Metabolism in Man provides an overview of the whole energy metabolic process among humans. The book is comprised of seven chapters that are organized according to the lecture series conducted by the author. The text first covers the basic principles of metabolism, and then proceeds to covering catabolism and resynthesis of simple units. Next, the book tackles the storage forms and control mechanisms. The remaining chapters detail the integration of pathways within cells and the metabolism of the body as a whole. The text will be of great use to students of biochemistry and other related fields, such as nutrition and nursing.

Book Description
This volume provides a comprehensive survey of the theory, practice, and techniques of calorimetry as applied to the study of energy metabolism in humans and animals. Calorimetry is used to estimate nutritional requirements of man and farm livestock and to evaluate different foods. It is also a powerful tool used in research into fundamental nutritional and physiological life processes and in the evaluation of stresses imposed by abnormal or severe environments. It is currently being applied in various branches of medical research and can be used as a diagnostic tool in hospitals for investigation of metabolic disorders. The authors discuss both direct calorimetry, which measures heat loss directly, and indirect calorimetry, where heat loss is inferred by measurement of some of the chemical byproducts of metabolism. In addition, guidance is provided to the instrumentation, technical problems, and precautions necessary to obtain accurate calorimetric measurements.

Book Description
Energy metabolism is central to life and altered energy expenditure (EE) is often cited as a central mechanism responsible for development of the obese phenotype. Resting EE, EE of physical activity, cold induced thermogenesis and thermic effect of feeding add to produce total EE but can also affect each other. It is thus very important that each component be well measured. Measuring energy expenditure by indirect calorimetry is extremely simple in theory but the practice if far more difficult. Taking into account temperature in small sized animals, measuring accurately the effect of activity on EE, correcting EE for body size body composition, age sex etc… add difficulties in producing reliable data. The goal of this Research Topic was to call for the practical experience of main investigators trained to practice calorimetry in order to get their feedback and the way they deal with the various and specific problems of humans and animal calorimetry. The goal is to share the questions/solutions experienced by the contributors to inititate a “guide of the good practices” that can be periodically updated and used by all those who are and will be interested in measuring energy metabolism from the 20g mouse to the human and large farm animals.

Book Description
"This book is the result of the 2nd International Symposium on Energy and Protein Metabolism and Nutrition. It presents the latest results on energy and protein metabolism and nutrition. It is oriented towards livestock science but also addresses general aspects of protein and energy metabolism as applied to animals or biomedical sciences. The book is based around the following five key topics: * Nutrition and mitochondrial functions * Regulation of body composition and/or product quality by tissue metabolism * ""Omics"" in metabolism and nutrition studies * Coordination between tissues for the metabolic utilisation of nutrients * From the parts to the whole or how to use detailed information to answer applied questions Widely different approaches ranging from fundamental to integrative approaches are applied to key concepts of nutrition. Fundamental research is translated into practical outcomes through active links with applied research and practical applications. The newest research techniques and methods are also addressed and the outcomes presented provide an integrated view of this topic. The conclusions may eventually be integrated into systems of nutritional recommendations as new nutritional challenges emerge. This book will be of interest to all professionals and researchers who concern themselves with developments in animal and human nutrition."
