Vitamins in Animal and Human Nutrition

Vitamins in Animal and Human Nutrition contains concise,
up-to-date information on vitamin nutrition for both animals and
humans. The author defines these nutrients and describes their
fascinating discovery, history and relationship to various diseases
and deficiencies. Discussion of vitamins also includes their
chemical structure, properties and antagonists; analytical
procedures; metabolism; functions; requirements; sources;
supplementation and toxicity. Vitamin-like substances, essential
fatty acids and vitamin supplementation considerations are also
examined.

This book will be useful worldwide as a textbook and as an
authoritative reference for research and extension specialists,
feed manufacturers, teachers, students and others. It provides a
well-balanced approach to both animal and clinical human nutrition
and compares chemical, metabolic and functional aspects of vitamins
and their practical and applied considerations. A unique feature of
the book is its description of the implications of vitamin
deficiencies and excesses and the conditions that might occur in
human and various animal species.
