Selenium (Se) is an essential dietary trace element participating in the regulation of various physiological functions in humans and farm animals through its incorporation into a range of selenoproteins. Low Se content in main feed ingredients is a common problem worldwide and dietary Se supplementation is a current practice in ruminant nutrition. Recent research clearly proved that sodium selenite, used for the last 50 years as a feed supplement, is not an optimal form of Se. However, use of organic selenium in dairy and beef diets can help meet Se requirement and maintain health/high immunocompetence, productive and reproductive performance. The goal of this book is to provide up-to-date information about the roles of Se in ruminant nutrition and health. A special emphasis is given to the role of selenium as an essential part of the integrated antioxidant system. The concept of using organic Se in ruminant nutrition is described in detail with emphasis on selenomethionine as a storage form of Se in the body. Also, specific Se deficiency-related disorders in ruminants are described and the importance of Se in growth, development, immunity and reproduction is demonstrated. Molecular mechanisms of protective effects of Se under stressful conditions of commercial milk and meat production are characterized. This book will be of practical importance to dairy and beef producers, to nutritionists and vets as well as for animal scientists, students of agricultural colleges and universities. It will also be of interest for researchers in areas related to environmental sciences, food sciences, physiology, etc.

This book provides information about selenium as an important part of integrated antioxidant systems in animal and human bodies responsible for maintaining health. It contains practical advice in relation to effective usage of selenium supplements, including optimal forms and doses. It also combines fundamental information on selenium biochemistry and metabolism. It also presents the most recent findings, unresolved puzzles and future directions for selenium research. In recent years, natural antioxidants have received tremendous attention in relation to human health and food quality. However, the scientific background of many health-promoting claims for natural antioxidants is not always understandable for the general public and needs further clarification. Furthermore, agricultural applications of antioxidants await further investigation.

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.

Vitamins in Animal and Human Nutrition contains concise, up-to-date information on vitamin nutrition for both animals and humans. The author defines these nutrients and describes their fascinating discovery, history and relationship to various diseases and deficiencies. Discussion of vitamins also includes their chemical structure, properties and antagonists; analytical procedures; metabolism; functions; requirements; sources; supplementation and toxicity. Vitamin-like substances, essential fatty acids and vitamin supplementation considerations are also examined. This book will be useful worldwide as a textbook and as an authoritative reference for research and extension specialists, feed manufacturers, teachers, students and others. It provides a well-balanced approach to both animal and clinical human nutrition and compares chemical, metabolic and functional aspects of vitamins and their practical and applied considerations. A unique feature of the book is its description of the implications of vitamin deficiencies and excesses and the conditions that might occur in human and various animal species.

Abstract: An authoratitive reference text for nutritionists, clinicians, and other health professionals provides an extensive review of the most pertinent scientific literature dealing the basic aspects of the present understanding of the roles of selenium (Se) in nutrition and health. Following a brief discussion of the chemistry and analysis of Se, attention is focused on: the occurrence of Se in the environment and in foods and feeds; the bioavailability of Se in foods and feeds; Se uptake, metabolism, a nd excretion; the biological functions of Se; Se deficiency diseases in laboratory animals and livestock; the role of Se in human nutrition and health; its role in immunity and infection; associations between Se and cancer; and the effects of Se toxicity in animals and humans. Numerous detailed data tables and illustrations are presented throughout the text, and literature citations are appended to each chapter.

Milk is nature’s most complete food, and dairy products are considered to be the most nutritious foods of all. The traditional view of the role of milk has been greatly expanded in recent years beyond the horizon of nutritional subsistence of infants: it is now recognized to be more than a source of nutrients for the healthy growth of children and nourishment of adult humans. Alongside its major proteins (casein and whey), milk contains biologically active compounds, which have important physiological and biochemical functions and significant impacts upon human metabolism, nutrition and health. Many of these compounds have been proven to have beneficial effects on human nutrition and health. This comprehensive reference is the first to address such a wide range of topics related to milk production and human health, including: mammary secretion, production, sanitation, quality standards and chemistry, as well as nutrition, milk allergies, lactose intolerance, and the bioactive and therapeutic compounds found in milk. In addition to cow’s milk, the book also covers the milk of non-bovine dairy species which is of economic importance around the world. The Editors have assembled a team of internationally renowned experts to contribute to this exhaustive volume which will be essential reading for dairy scientists, nutritionists, food scientists, allergy specialists and health professionals.
