Selenium in Nutrition and Health
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.
Natural Antioxidants in Avian Nutrition and Reproduction
The main aim of this volume is to provide up-to-date information about natural antioxidants in relation to avian physiology, nutrition and reproduction. A comparison with farm animals and humans is made where appropriate.
Current advances in selenium research and applications
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 usag...
Selenium in ruminant nutrition and health
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 i...
Selenium in Poultry Nutrition and Health
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.
Silymarin Puzzle
For the last 30 years, polyphenols were in the centre of research work worldwide. Silymarin, an extract from a medicinal plant Silybum marianum, also known as milk thistle, has a special place in this group, having been used in human medicine for the management of liver diseases since ancient times. Accumulating scientific evidence indicates that silymarin is characterised by a wide range of protective pharmacological activities and this topic has received tremendous attention in recent years. However, until now there has been no single monograph addressing major questions related to silymarin chemistry, biochemistry and practical applications. The goal of this book is to provide up to date ...
Selenium in Ruminant Nutrition and Health
This is the first monograph devoted to biological roles of selenium in nutrition and health of ruminants including dairy and beef cows and small ruminants. It is written by the world's expert in the area.
Selenium in Pig Nutrition and Health
The goal of this book is to provide up to date information about the roles of Se in pig nutrition and health. Specific Se-deficiency related disorders in pigs are also 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 pig production are characterised.
Vitagenes in Avian Biology and Poultry Health
The goal of this book is to provide up to date information about the roles of vitagenes in avian biology and poultry health. Special emphasis is put on the role of vitagenes as an essential part of the redox homeostasis maintenance, stress adaptation, and development of adaptive homeostasis. The book provides data to indicate that nutritional modulation of vitagenes is a new direction in nutritional sciences. Practical results of the successful usage of the vitagene concept in poultry production are also presented.
Bioactive Egg Compounds
Bioactive Egg Compounds presents the latest results and concepts in the biotechnological use of egg compounds. Following an introduction to the different compounds of egg white, yolk and shell, the nutritive value of egg compounds is discussed. The text describes procedures for processing egg compounds to improve their nutritive value, including so-called enriched eggs. Also described is the isolation and application of egg compounds with special properties, such as antibiotic action.
