Principles Of Animal Nutrition And Feed Technology

The field of animal nutrition and feed technology has moved forward at an accelerated pace year by year. The present book is a result of the author’s long experience in the field whereby which the information documented has been presented in a simple, illustrative and lucid manner keeping in the mind the level of the readers. Less important information has been eliminated, while the general framework, character and flavour of the literature have been preserved, the text presents the animal nutrition and feed technology in an updated manner with the interpretation for the theory in practical manner.

The text presents the principles of nutrition and their applications to feeding practice.

Animals are biological transformers of dietary matter and energy to produce high-quality foods and wools for human consumption and use. Mammals, birds, fish, and shrimp require nutrients to survive, grow, develop, and reproduce. As an interesting, dynamic, and challenging discipline in biological sciences, animal nutrition spans an immense range from chemistry, biochemistry, anatomy and physiology to reproduction, immunology, pathology, and cell biology. Thus, nutrition is a foundational subject in livestock, poultry and fish production, as well as the rearing and health of companion animals. This book entitled Principles of Animal Nutrition consists of 13 chapters. Recent advances in biochemistry, physiology and anatomy provide the foundation to understand how nutrients are utilized by ruminants and non-ruminants. The text begins with an overview of the physiological and biochemical bases of animal nutrition, followed by a detailed description of chemical properties of carbohydrates, lipids, protein, and amino acids. It advances to the coverage of the digestion, absorption, transport, and metabolism of macronutrients, energy, vitamins, and minerals in animals. To integrate the basic knowledge of nutrition with practical animal feeding, the book continues with discussion on nutritional requirements of animals for maintenance and production, as well as the regulation of food intake by animals. Finally, the book closes with feed additives, including those used to enhance animal growth and survival, improve feed efficiency for protein production, and replace feed antibiotics. While the classical and modern concepts of animal nutrition are emphasized throughout the book, every effort has been made to include the most recent progress in this ever-expanding field, so that readers in various biological disciplines can integrate biochemistry and physiology with nutrition, health, and disease in mammals, birds, and other animal species (e.g., fish and shrimp). All chapters clearly provide the essential literature related to the principles of animal nutrition, which should be useful for academic researchers, practitioners, beginners, and government policy makers. This book is an excellent reference for professionals and a comprehensive textbook for senior undergraduate and graduate students in animal science, biochemistry, biomedicine, biology, food science, nutrition, veterinary medicine, and related fields.

The book has been written specifically to cater the need of undergraduate/postgraduate students of veterinary science by providing all the needed information comprehensively, as per the new VCI regulations, modified in the year 2009-2010 on animal nutrition subject at a single course. Complete information in a comprehensible way is the watchword of the book. The book consists of three parts and each part provides a structured approach to learning by covering all the topics in a uniform and systematic format. The topics under each part have been carefully designed to conform to the VCI syllabus. Part I deals with principles of animal nutrition and feed technology which comprehensively covered about the proximate principles and estimation of common macro elements like calcium and phosphorus. It also includes about the cell wall fractionation and estimation of common toxic principles present in feeds. Part II deals with applied animal nutrition-I, where the feeding on ruminant animals specifically the cattle, buffalo, sheep and goats in their different physiological stages are discussed and requirements of different nutrients as well as formulation of their respective ration has been taken care of. Part III deals with applied animal nutrition-II, where the feeding on non-ruminant animals specifically the swine and poultry in their different physiological stages are discussed and requirements of different nutrients as well as formulation of their respective diet has been taken care of. In addition to that principles of mixing and compounding of feed has also been considered. The book is similarly useful for the post graduate students of animal sciences, teachers and scientists of animal nutrition discipline, personnel of feed industry involved in feed manufacturing and marketing, field veterinarian, animal husbandry extension worker and progressive animal farmers and animal lovers.
