Animals are biological transformers of dietary matter and energy to produce high-quality foods and wools for human consumption and use. Mammals, birds, fish, and shrimp require nutrients to survive, grow, develop, and reproduce. As an interesting, dynamic, and challenging discipline in biological sciences, animal nutrition spans an immense range from chemistry, biochemistry, anatomy and physiology to reproduction, immunology, pathology, and cell biology. Thus, nutrition is a foundational subject in livestock, poultry and fish production, as well as the rearing and health of companion animals. This book entitled Principles of Animal Nutrition consists of 13 chapters. Recent advances in biochemistry, physiology and anatomy provide the foundation to understand how nutrients are utilized by ruminants and non-ruminants. The text begins with an overview of the physiological and biochemical bases of animal nutrition, followed by a detailed description of chemical properties of carbohydrates, lipids, protein, and amino acids. It advances to the coverage of the digestion, absorption, transport, and metabolism of macronutrients, energy, vitamins, and minerals in animals. To integrate the basic knowledge of nutrition with practical animal feeding, the book continues with discussion on nutritional requirements of animals for maintenance and production, as well as the regulation of food intake by animals. Finally, the book closes with feed additives, including those used to enhance animal growth and survival, improve feed efficiency for protein production, and replace feed antibiotics. While the classical and modern concepts of animal nutrition are emphasized throughout the book, every effort has been made to include the most recent progress in this ever-expanding field, so that readers in various biological disciplines can integrate biochemistry and physiology with nutrition, health, and disease in mammals, birds, and other animal species (e.g., fish and shrimp). All chapters clearly provide the essential literature related to the principles of animal nutrition, which should be useful for academic researchers, practitioners, beginners, and government policy makers. This book is an excellent reference for professionals and a comprehensive textbook for senior undergraduate and graduate students in animal science, biochemistry, biomedicine, biology, food science, nutrition, veterinary medicine, and related fields.
In the years since the third edition of this indispensable reference was published, a great deal has been learned about the nutritional requirements of common laboratory species: rat, mouse, guinea pig, hamster, gerbil, and vole. The Fourth Revised Edition presents the current expert understanding of the lipid, carbohydrate, protein, mineral, vitamin, and other nutritional needs of these animals. The extensive use of tables provides easy access to a wealth of comprehensive data and resource information. The volume also provides an expanded background discussion of general dietary considerations. In addition to a more user-friendly organization, new features in this edition include: A significantly expanded section on dietary requirements for rats, reporting substantial new findings. A new section on nutrients that are not required but that may produce beneficial results. New information on growth and reproductive performance among the most commonly used strains of rats and mice and on several hamster species. An expanded discussion of diet formulation and preparationâ€"including sample diets of both purified and natural ingredients. New information on mineral deficiency and toxicity, including warning signs. This authoritative resource will be important to researchers, laboratory technicians, and manufacturers of laboratory animal feed.
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.
This book covers the wide area of developmental physiology of the intestine: changes in the structure and function of the gut during perinatal period and weaning in mammals, role of nutrients (in particular colostrum and milk), neuroendocrine function of the intestine, intestinal motility, secretion and absorption and their neurohormonal regulation, novel knowledge on gut metabolism, and the structural and functional expression of circadian variability in the gut. It also contains unique information on the luminal action of gut regulatory peptides, and the role of the electric current generated by intestinal smooth muscle on gastrointestinal microbial growth.
Nutrition has long been considered more the domain of medicine and agriculture than of the biological sciences, yet it touches and shapes all aspects of the natural world. The need for nutrients determines whether wild animals thrive, how populations evolve and decline, and how ecological communities are structured. 'The Nature of Nutrition' addresses nutrition's enormously complex role in biology, both at the level of individual organisms and in their broader ecological interactions.

By 2050 the world's population is projected to grow by one-third, reaching between 9 and 10 billion. With globalization and expected growth in global affluence, a substantial increase in per capita meat, dairy, and fish consumption is also anticipated. The demand for calories from animal products will nearly double, highlighting the critical importance of the world's animal agriculture system. Meeting the nutritional needs of this population and its demand for animal products will require a significant investment of resources as well as policy changes that are supportive of agricultural production. Ensuring sustainable agricultural growth will be essential to addressing this global challenge to food security. Critical Role of Animal Science Research in Food Security and Sustainability identifies areas of research and development, technology, and resource needs for research in the field of animal agriculture, both nationally and internationally. This report assesses the global demand for products of animal origin in 2050 within the framework of ensuring global food security; evaluates how climate change and natural resource constraints may impact the ability to meet future global demand for animal products in sustainable production systems; and identifies factors that may impact the ability of the United States to meet demand for animal products, including the need for trained human capital, product safety and quality, and effective communication and adoption of new knowledge, information, and technologies. The agricultural sector worldwide faces numerous daunting challenges that will require innovations, new technologies, and new ways of approaching agriculture if the food, feed, and fiber needs of the global population are to be met. The recommendations of Critical Role of Animal Science Research in Food Security and Sustainability will inform a new roadmap for animal science research to meet the challenges of sustainable animal production in the 21st century.
