This book is intended to be a companion volume to 'Protein Nutrition in Ruminants' (1982, Academic Press), which emphasized both the role of proteins and new systems for their evaluation. Here the focus is on energy-yielding nutrients and problems involved in evaluating them. Nonetheless in both volumes there is explicit recognition of the interdependence of energy and protein nutrition. I have not attempted to review comprehensively all the literature relating to ruminant energy nutrition and must apologize to colleagues whose work is not fully reported. Where possible tables and figures are taken from the studies of our group at the Rowett Research Institute since, if for no other reason, I am most familiar with these data. I have first considered the nutrition of the newborn and have stressed the role of behaviour 'in determining whether nutrients enter or bypass the rumen. The development of the rumen, the of anaerobic fermentation and the roles of various principles . species of rumen bacteria, protozoa and fungi in relation to different substrates, are summarized. This is followed by accounts of the factors affecting the utilization of different substrates and the v vi Preface absorption and metabolism of the end-products of fermentation and digestion, together with estimates of digestive capacity in various segments of the gut. The ruminant's requirements for energy-yielding nutrients is considered in relation to the per formance of various activities and to environmental conditions, particular attention being paid to the requirement for glucose precursors.

Lipid Metabolism in Ruminant Animals is a nine-chapter book that first discusses the anatomy, physiology, and microbiology of the ruminant digestive tract. Subsequent chapters center on lipid metabolism in the rumen; digestion, absorption and transport of lipids in ruminant animals; the composition, structure and function of lipids in the tissues of ruminant animals; and the effects of diet and other factors on the lipid composition of ruminant tissues and milk. Other chapters focus on lipid metabolism in the mammary gland, adipose tissue, liver, and other selected tissues of ruminant animals.

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.

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.

Ruminants were domesticated in the Middle East about 10,000 years ago and have since become an inseparable part of human diet, society, and culture. Ruminants can transform inedible plant fiber and non-protein nitrogen into meat, milk, wool and traction, thus allowing human utilization of non-tillable land and industrial by-products. The nutritional flexibility of ruminants is conferred by the rumen´s complex microbial community. Driven by rising income and population growth in emergent economies, the global demand for livestock products, including milk and meat from ruminants, has been increasingly growing, and is predicted to continue growing in the next few decades. The increase in production necessary to satisfy this rising demand is putting much pressure on already dwindling natural resources. There are also concerns about the emissions of methane and nitrous oxide, potent greenhouse gases associated to ruminant production. The need to make ruminant production more efficient in the use of natural resources poses a big challenge to ruminant science, and within it, rumen microbiology. Recent years have seen important advances in basic and applied rumen microbiology and biochemistry. The knowledge generated has significant implications for the efficiency and sustainability of ruminant production and the quality of ruminant products for human health. The present compilation is an update of recent advances in rumen microbiology and ruminant digestion and fermentation, including original research, reviews, and hypothesis and theory articles. We hope that the experimental results, discussion, models and ideas presented herein are useful to foster future research contributing to sustainable ruminant production.

The first edition of this book. Published in 1993, was very well received as providing a comprehensive review of the digestion and metabolism of ruminant animals. Since its publication, much new research has been conducted in the subject and knowledge has increased. This new edition includes Dr. Dijkstra as an additional editor and four completely new chapters. These cover: the gas production technique in feed evaluation; the relationship between pasture characteristics and animal performance; calorimetry; and feed processing. Other chapters have been expanded or updated as appropriate.

The book is intended to provide in-depth reviews of the recent advances in major areas of metabolism in growing domestic animals. The study of metabolism represents a nexus of biological phenomenon that integrates the impact of nutrition, physiology, endocrinology, immunology, biochemistry, and cell biology in an organism. The development of new methodological techniques and experimental approaches have provide scientists with a greater understanding of how key nutrients or substrates are metabolized at the cellular, organ, and whole animal level. This book presents contributions from leading scientists in nutrition and physiology that highlight important new developments in interorgan and tissue-specific metabolism of protein and amino acids, lipids and fatty acids, and carbohydrates in monogastric and runinant species. Authors will describe the impact of specific biochemical pathways and expression of critical enzymes, routes of nutrient or substrate input, and anatomical or structural influences on the rates of metabolism in a given tissue or cell type. Major substrates/ fuels for oxidative metabolism, key signaling pathways, and intracellular molecules that regulate the major metabolic processes will be described. Also included is how the metabolism of growing animals is influenced by ontogeny, stage of differentiation, and major changes in diet, or the environment. The concepts and specific findings in each area are discussed in the context of their impact on the nutrient requirements, growth, environmental impact, healt and well-being of animals. The book will be a useful reference for research scientists, teachers and students interested in and advanced understanding of metabolism in growing animals. The book is written by leading experts and highlights some of the most recent advances in the field of metabolism. It is a useful reference for researchers and advanced level graduate students in nutrition, physiology and animal science. Presents recent advances in the field of metabolism.
