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.

Metabolic Diseases in Farm Animals discusses metabolic diseases in farm livestock, focusing on four clinical syndromes—parturient hypocalcaemia, hypomagnesaemia, ketosis, and bloat. This book discusses metabolic disorders associated with water, calcium, magnesium, sodium, potassium, nitrogen, and phosphorus. The parturient paresis, which causes considerable metabolic stress and disrupts the daily pattern of feeding and digestion of dairy cows is also elaborated. This text covers the changes in mineral metabolism at parturition; factors predisposing dairy cows to parturient paresis; cause of paresis in milk fever; and downer syndrome in dairy cows. The complexity of energy metabolism and its associated disorders are likewise described. This publication is a good source for veterinarians and livestock farmers concerned with metabolic diseases in farm animals.

In the past decade, animal scientists have learned that administering recombinantly derived somatotropin (growth hormone) to cows improves milk production and that giving beta-adrenergic agonists to meat animals improves productivity and leanness. In order for these metabolic modifiers to yield benefits, however, sound management of the animals' nutrition is necessary. This volume reports on how these substances work in the animals' metabolism, what effects they might have on nutrient requirements of domestic livestock, and what information should be developed further by investigators. The book explores the current understanding of the biology, structure, mechanisms of action, and treatment effects of somatotropin, beta-adrenergic agonists, and anabolic steroids. A companion volume to the Nutrient Requirements of Domestic Animals series, this authoritative volume will be required reading for animal scientists, researchers, veterinarians, livestock farmers, and faculty and students in university animal veterinary science programs.

Protein Deposition in Animals explores the factors controlling protein deposition in farm animals including fish, poultry, and ruminants. Topics covered range from protein biosynthesis in eukaryotic cells and protein metabolism in intact animals to whole-body amino acid metabolism, synthesis of egg proteins, and metabolism of the fetus. The energy costs of protein metabolism, dietary constraints on nitrogen retention, and metabolism in muscle are also discussed. Emphasis is placed on the factors that influence protein production by animals. This book is comprised of 15 chapters; the first of which explains some fundamental aspects of protein synthesis, followed by a topic of the molecular control of protein breakdown. Two chapters then consider the measurement of whole-body protein metabolism and the integration of the metabolism of individual organs with the rest of the animal. Two 'tissues', the muscle and the fetus, are singled out for detailed analysis in subsequent chapters, while another chapter describes the synthesis of egg proteins. The factors that influence overall nitrogen retention by the animals are also examined, along with the energy costs of protein deposition, hormonal influences on protein deposition, and the use of anabolic agents to manipulate growth. Two chapters, one on poultry and the other on ruminants, are concerned with predicting rates of protein deposition. This text concludes by discussing the protein metabolism in fish. This book will be of interest to scientists working in the fields of applied biochemistry, animal nutrition and physiology, physiology, and agriculture.

Mineral Nutrition of Animals reviews the research on the mineral nutrition of animals. This book explores the biological function and metabolism of minerals in the body, as well as mineral feeding of various species of farm animals. Topics range from water metabolism and mineral composition of feeds to the physiological role of macroelements such as calcium and potassium and microelements such as iron and copper. This text is comprised of 16 chapters; the first of which provides a historical overview of the science of mineral feeding of animals; mineral elements and their function in animal nutrition; and mineral feeding of animals under industrial conditions. The chapters that follow present general information on minerals, describe the link between biogeochemical regions and biochemical ecology, and analyze the factors affecting the mineral composition of animals' bodies. The reader is also introduced to water metabolism and the water requirements of animals; the metabolism of minerals absorbed into the digestive tract; and the kinetics of mineral metabolism in the blood, organs, and tissues. The next section is devoted to mineral feeding of various species of farm animals such as cattle, sheep, pigs, and poultry. This text concludes by looking at methods of controlling the adequacy of farm animals' mineral diet. This book will be of interest to students and practitioners in agriculture and food science.

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.
