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.
Although nutrition is thought to be a completed science, it is not, neither in theory or practice. Rationale for Animal Nutrition addresses the incorrect ideas and unsettled issues, and far beyond the standard, protein builds muscle and vitamin A is good for the eyes, nutritional pabulum. Dr. Wysong?s experience in veterinary surgery and medicine, nutritional and food science research, and building and running food manufacturing facilities gives him the 'in the trenches? insight to take issue with a wide variety of common nutritional givens. These are some of the myths he challenges:? Processed packaged pet food are "100% complete and balanced"? Synthetic nutrients are the same as natural? Better digestibility equals better food? Supplementing commercial pet foods is dangerous? NRC requirements are well founded in fact? A food's merit can be determined by its list of ingredients or analyses? Foods in paper bags can have a six month or greater shelf-life? Modern nutrition is better than that of our ancestors? More technology and more medicine will mean less disease? Science knows what nutrients we requireDr. Wysong gives readers fundamental, philosophic understandings of their place - and that of their companion animals - in the natural order of things. This empowers people with the insight needed to make independent, healthful decisions when confronting the confusing and dangerous commercial marketplace.
This book contains 16 chapters by individual authors reviewing feed enzymes within the context of their mode of action, interaction with intestinal physiology, economic and environmental impacts, and application of the technology to the diets of various livestock species.
Mathematical modelling is increasingly applicable to the practical sciences. Here, mathematical approaches are applied to the study of mechanisms of digestion and metabolism in primary animal species. It also explores common themes between species, and provides an integrated approach to mathematical modelling in animal nutrition.
This book comprises the contributions of the international workshop Boron 2001 which was aimed at gathering all relevant information on recent developments in boron research in soils, plants, animal and men over the past years. Review articles and original contributions deal with both applied and basic aspects in this area, comprising topics such as methods for B determination, the physiological functions of boron in plant and animal metabolism, including use of 10B for diagnostic purposes and cancer treatment. Genetic and molecular aspects of boron efficiency and tolerance to toxic levels in plants and the early physiological reactions to boron deprivation are further important topics of this volume. The role of boron for reproductive development is dealt with in further contributions. Furthermore, improved methods for the diagnosis of the available boron status in soils, plants appropriate timing and leaf fertilizer application are addressed. Special emphasis is given in the contributions to highlight the most recent developments in the aforementioned areas.

The science of animal nutrition has made significant advances in the past century. In looking back at the discoveries of the 20th century, we can appreciate the tremendous impact that animal nutrition has had on our lives. From the discovery of vitamins and the sweeping shift in the use of oilseeds to replace animal products as dietary protein sources for animals during the war times of the 1900s-to our integral understanding of nutrients as regulators of gene expression today-animal nutrition has been the cornerstone for scientific advances in many areas. At the milestone of their 70th year of service to the nation, the National Research Council's (NRC) Committee on Animal Nutrition (CAN) sought to gain a better understanding of the magnitude of recent discoveries and directions in animal nutrition for the new century we are embarking upon. With financial support from the NRC, the committee was able to organize and host a symposium that featured scientists from many backgrounds who were asked to share their ideas about the potential of animal nutrition to address current problems and future challenges.
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.
