Amino acids (AAs) are not only building blocks of protein, but are also signalling molecules as well as regulators of gene expression and the protein phosphorylation cascade. Additionally, AAs are key precursors for syntheses of hormones and low-molecular weight nitrogenous substances with each having enormous biological importance. For example, physiological concentrations of AA metabolites (e.g., nitric oxide, polyamines, glutathione, taurine, thyroid hormones, and serotonin) are required for cell functions. Growing evidence shows that humans and animals have dietary requirements for all proteinogenic AAs. Mammals, birds and fish also have species- and age-dependent needs for some AA-related substances. However, elevated levels of other products (e.g., ammonia, homocysteine, H2S, and asymmetric dimethylarginine) are pathogenic factors for neurological disorders, oxidative stress, and cardiovascular disease. Thus, optimal amounts of AAs and their ratios in diets and circulation are crucial for whole body homeostasis and health. Adequate provision of one or a mixture of functional AAs or metabolites may be beneficial for ameliorating health problems at various stages of the life cycle (e.g., fetal growth restriction, neonatal morbidity and mortality, weaning-associated intestinal dysfunction and wasting syndrome, obesity, diabetes, cardiovascular disease, the metabolic syndrome, and infertility). Dietary supplementation of these nutrients can also optimize the efficiency of metabolic transformations to enhance muscle growth, milk production, and athletic performance, while preventing excess fat deposition and reducing adiposity. Therefore, functional AAs hold great promise in improving the growth, health and well-being of individuals.

The latest edition of this classic text, now in a larger format with improved artwork, continues to provide a clear and comprehensive introduction to the science and practice of animal nutrition. Animal Nutrition covers four main areas. Chapters 1-9 explain the basic chemistry and biochemistry of feed constituents, digestion and metabolism; Chapters 10-18 evaluate the energy and nutrient content of feedstuffs and discuss the assessment of nutritional requirements and ration formulation; Chapters 19-25 describe the characteristics of commonly used feedstuffs such as forages, concentrates and by-products; and the Appendix provides comprehensive tables on the composition of foods and feeding standards for dairy and beef cattle, sheep, pigs and poultry, and horses.

This edited volume comprehensively highlights recent advances in the metabolism, nutrition, physiology, and pathobiology of amino acids in all the systems of humans and other animals (including livestock, poultry, companion animals, and fish). It enables readers to understand the crucial roles of amino acids and their metabolites in the health and diseases of the circulatory, digestive, endocrine, immune, muscular, nervous, reproductive, respiratory, skeletal, and urinary systems, as well as the sense organs (eyes, ears, nose, skin, and tongue). Readers will learn that amino acids are not only the building blocks of protein, but are also signalling molecules, as well as regulators of gene expression, metabolic processes and developmental changes in the body. This knowledge will guide nutritional practices to improve the growth, development and health of humans and other animals, as well as prevent and treat chronic (e.g., obesity, diabetes, and cardiovascular disorders) and infectious (e.g., bacterial, fungal, parasite, and viral) diseases. Editor of this volume is an internationally recognized expert in nutritional biochemistry. He has over 38 years of experience with research and teaching at world-class universities in the area of amino acid biochemistry, nutrition, and physiology. He has published more than 625 papers in peer-reviewed journals, 62 chapters in books, and authored two text/reference books, with an H-index of 117 and more than 55,000 citations in Google Scholar. This publication is a useful reference for professionals as well as undergraduate and graduate students in animal science, biochemistry, biomedical engineering, biology, human medicine, food science, kinesiology, nursing, nutrition, pharmacology, physiology, toxicology, veterinary medicine, and other related disciplines. In addition, all chapters provide general and specific references to amino acids in systems health for researchers and practitioners in biomedicine, animal and plant agriculture, and aquaculture, and for government policy makers.

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.
