This textbook on the Micronutrient Nutrition in Farm Animals presents concise, up-to-date information on mineral and vitamin nutrition for livestock and poultry. The text in this textbook is categorized into three sections i.e. section A - Mineral Nutrition and section B - Vitamin Nutrition and section C - Role of Micronutrients in Oxidative Stress and Immunity. The mineral section is comprised of 20 chapters; which provide a comprehensive overview of the mineral’s history, dietary sources, distribution in the body, metabolism, biological functions, as well as their requirements, deficiency and toxicity for various animals and mineral status of common feedstuffs. The vitamin section is comprised of 16 chapters and devoted to the history of vitamins, classification, structure of different vitamins, sources, absorption and metabolism, biological functions, requirements and hypervitaminosis. The role of micronutrients in oxidative stress and immunity detailed about the oxidative stress and its impact on the immune status. A unique feature of this book is the detailed description of the practical implications of micronutrient deficiencies and excesses, and of the conditions that might result. The book is intended for undergraduate and post-graduate students with a basic understanding of animal and veterinary science. This book also forms a useful reference for veterinary practitioners and those concerned with human nutrition.

She joined the Agricultural Research Services in 1985. In the early years of her service, she worked in the area of protection of proteins and lipids forimproved production performance of dairy animals. Since the last one and a half decade, she is doing research in the area of micronutrients with an emphasis on mineral nutrition. She had conducted a number of experiments to study the effect of different toxic metals (As, Cd and Pb) on growth and milk production as well as the secretion of these metals through milk. Studies were also convened in the direction of amelioration of adverse effects of these toxic metals by dietary supplementation of certain binders and anti-oxidants. Apart from this, generated the database on the status of toxic and essential heavy metals in feeds, fodders milk and water from Haryana. Presently, she is working in the area of newer trace elements (chromium, boron and vanadium) which may have a beneficial role in ruminant rations. The dietary requirements of Cr have been established for growing and lactating animals which can be advocated in mineral mixtures for better immune health as well as productive performance even under physiological or climatic stress conditions. She also generated the information on the bioavailability of major and trace minerals from commonly used feedstuffs. During her research carrier, Dr. Mani has guided 15 Masters and 7 Ph.D. students. She has published more than 80 research papers in high impact journals and has several invited papers. She has published several other publications like folders, technical bulletin, technical papers, book chapters and popular articles to her credit. She has authored and edited technical manuals for mineral analysis, a handbook on milk analysis and also contributed to “Nutrient Requirements of Cattle and Buffaloes” published by ICAR. To her credit are also two books in Hindi which provide information on feeding aspects of dairy animals. She developed technology for the formulation of area specific mineral mixture and anionic mineral mixture and the latter has proved a potential strategy for transition animals and is showing good results at farmer’s door. Dr. Mani is associated with a number ofresearch projects. She has a membership in various professional societies. Dr. Gulab Chandra was born in District Siddharthnagar, Uttar Pradesh.
