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.

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 information about silymarin chemistry, biochemistry and molecular mechanisms of protective actions of this phytochemical with a special emphasis to its vitagene- and transcription factor-modulating properties. Silymarin applications in human diseases, including hepatoprotection, neuroprotection, anti-diabetic, anti-arthritis and other protective activities are reviewed. Immunomodulating, anti-inflammatory, anti-toxic protective activities of silymarin are characterised in detail. Practical applications of silymarin in poultry and animal industry with a special emphasis on its protective roles in gut health maintenance are also presented. This book will be of practical importance to medical and pharmaceutical scientists, including medical doctors, pharmacists, consultants, etc. as well as to poultry/animal scientists, poultry producers, nutritionists and vets, as well as to students of medical, biological and agricultural backgrounds. It can also be of interest for researchers in areas related to physiology, biochemistry, nutrition and veterinary medicine.
