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.

This book is an up to date reference work covering all aspects of macro and trace element nutrition in farm livestock. Sufficient information is given on metabolism, functions and interactions to explain why needs, feeds and imbalances are not always easy to define or anticipate. The major emphasis is on the mineral nutrition of ruminant livestock since they are most likely to be affected by imbalances but where pigs and poultry are the more vulnerable, extensive coverage of the non-ruminant is given. This new edition of a highly successful text has been thoroughly revised and significantly expanded. Many chapters have been extensively updated and several chapters on new topics introduced. * Calcium, phosphorus, sodium and potassium are now treated separately * Over 40 new figures are presented, and extensive use made oftables to summarise important data * Chapters on trace elements have been drastically revised * Claims for enhanced availability for new chelated sources arecritically reviewed * Completely new chapters focus on: The unique need of the ruminant for elemental sulphur Occasionally beneficial elements and essentially toxic elements The improved conduct and interpretation of supplementation trials

This practical book provides crucial information necessary to formulate diets with appropriate amounts of amino acids, minerals, and vitamins. The factors that influence how well animals obtain these critical nutrients and methods for determining bioavailability are reviewed in this comprehensive text. In addition, data from both ruminants and nonruminants are included as well as established estimates of bioavailability for particular feed stuffs and feed supplements.

This comprehensive textbook and reference manual presents concise, up-to-date information on mineral nutrition for livestock and poultry, as well as comparative aspects with laboratory animals and humans. Chapters are organized by established and most common minerals, and present information on each mineral's history, properties, distribution, and natural sources, as well as their requirements, metabolism, functions, deficiencies, supplementation methods, and toxicity for various animals. Those minerals for which naturally occurring deficiencies or excesses are known to be of economic importance are emphasized. A unique feature of this book is the description of the practical implications of mineral deficiencies and excesses, and of the conditions that might result. A large number of classic photographs illustrate mineral deficiencies and toxicities in farm livestock, laboratory animals and humans. Furthermore, it places strong emphasis on mineral supplementation in each chapter, and devotes an entire chapter to this subject.

Excess minerals in the diet and water of animals can have an adverse effect on animal health, consumers, and the environment. Preventing unsafe mineral exposure is a fundamental part of animal nutrition and management. At the request of the Food and Drug Administration, the National Academies convened a committee to make recommendations on animal tolerances and toxic dietary levels, updating a 1980 report on mineral tolerance in domestic animals. Based on a review of current scientific data and information, the report sets a "maximum tolerable level" (MTL) for each mineral as it applies to the diets of farm animals, poultry, and fish. The report includes an analysis of the effects of toxic levels in animal diets, and it identifies elements that pose potential human health concerns. The report recommends research that includes a better characterization of animal exposure to minerals through feedstuffs; a better understanding of the relationship between mineral concentrations in feed and water and the levels in consumer products such as meat, milk, and eggs; and more research on the maximum tolerable level of minerals for aquatic and companion animals.

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.
