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.

Abstract: A comprehensive, authoritative report of a National Research Council subcommittee reviews current knowledge concerning selenium (Se) in nutrition for nutrition, food, and health professionals. The report focuses on: the chemistry of Se and its analysis; Se distribution in soils, plants, animal feeds, human foods, and water; the Se cycle in nature; biochemical functions of Se (e.g., associations with glutathione peroxidase; nutritional and metabolic inter-associations); Se dietary forms and its absorption, transport, retention, distribution, and metabolism; Se nutritional aspects (dietary requirements and deficiencies in animals, and role in human nutrition); the toxic effects of excess Se; and the effects of high and low Se exposures in human health. A summary of the findings of this report and an extensive list of literature references cited are appended. (wz).

The goal of this book is to provide up to date information about the roles of Se in poultry nutrition and health. A special emphasis is given to the role of selenium as an essential part of the integrated antioxidant system. Se in feed and organic Se are characterised in detail with emphasis to selenomethionine as a storage form of Se in the body. Also specific Se-deficiency related diseases in poultry are described and the importance of Se in growth, development, immunity and reproduction is demonstrated. A link between poultry industry and human health via production of Se-eggs and Se-enriched meat is shown.

The Role of Selenium in Nutrition reviews the most pertinent scientific literature dealing with the basic aspects of the present understanding of the roles of selenium (Se) in nutrition and health. The book begins with a general discussion of Se, covering its various forms, chemistry and physical properties, and techniques for Se analysis. This is followed by separate chapters on the environmental aspects of Se, including its presence in mineral deposits, soils, water, air, and uptake by plants; Se contents of human foods and animal feedstuffs; biological utilization of dietary Se; and absorption, excretion, metabolism, and tissue concentrations of Se. Subsequent chapters deal with the biochemical functions of Se; Se-related diseases of animals and livestock; the role of Se in human health and in support of normal immune function and disease resistance; and the relationship of Se and cancer. The final chapter reviews the evidence concerning the toxicity of Se compounds and sets this in perspective with current knowledge of the roles of Se in nutrition and health, and of the normal exposures of animals and humans to Se compounds.

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.

Selenium plays a fascinating and still poorly understood role in the function of living cells and therefore in human health. Starting with investigations over 60 years ago into its role as a toxic agent in livestock disease, selenium studies have progressed rapidly with the application of tools from immunology and molecular biology. Selenium is now known to be important in human and animal nutrition, has been discovered as a structural component of so-called selenoproteins, and may play a number of physiological roles, ranging from cancer protection to hormone metabolism. Selenium in Biology and Human Health presents research syntheses on a range of topics involving selenium, written by specialists from around the world. It will be of interest to cell biologists and physiologists, nutritional scientists, and animal health researchers.

Selenium (Se) is an essential dietary trace element participating in the regulation of various physiological functions in both animals and humans through its incorporation into selenoproteins as the amino acid selenocysteine. Among many minerals Se has a special place being the most controversial trace element with a narrow gap between essentiality and toxicity. Indeed there are important environmental issues considering selenium as a pollutant from the one hand and global selenium deficiency on the other. In fact, Se deficiency is considered as a risk factor for the development of various diseases in human and animals. Decreased Se availability from soils as a result of low soil pH and usage of synthetic fertilizers is the major concern in European countries causing inadequate Se levels in food and feeds. Furthermore, it seems likely that sodium selenite used for the last 30 years as a feed supplement is not an optimal form of Se and the usage of organic selenium in animal diets could help to maintain optimal Se status as well as high immunocompetence, productive and reproductive performance. The aim of the present volume is to provide updated information on several important Se-related subjects, including Se status in Europe and ways of its improvement, advances in Se analysis and speciation in biological material, roles of selenium in poultry, pig and ruminant nutrition. Production of functional Se-enriched food, the relationship between selenium and mycotoxins, polyunsaturated fatty acids as well as reoviruses are also addressed. This collection of articles will provide nutritionists, veterinarians, human doctors, researchers and any other readers with new insights into the exciting world of the goddess of the moon - SELENIUM.
