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 successfu...

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.

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...

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 pollutan...
