In this new edition, the editor has retained chapters imparting strength to the first version, while introducing authors with new ideas and vision, as well as chapters on other animals such as cats and dogs. The book is theamatically structured and includes chapters of an introductory and general nature with applications to a wide range of animal species, species-related sections, including pigs, poultry, ruminants and other animals and cover applications and perspectives.

Bringing together international expertise in rabbit production, topics covered in this fully updated volume include digestive physiology, feed formulation and product quality, as well as feeding strategies, feed processing, feed management around weaning and the relationship between nutrition and intestinal health. Brand new to this edition, the chapters also discuss the development of immune response and the role of intestinal microbiota, new dietary sources and additives, and feeding behaviour in pasture and organic feeding. A valuable resource for researchers and students of animal nutrition and production, this book provides a comprehensive, research-based review of nutrition for these important animals.

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.

Poultry are farmed and are important sources of protein throughout the world. All students of agriculture are likely to be required to study poultry science to at least an introductory level. However, hitherto there has been no suitable textbook serving the needs of students taking a general introductory course in poultry science. This book aims to fill this gap. It explains the science underlying the productive processes of growth, reproduction and incubation. The applications of nutrition and breeding techniques are described. The book covers all the commercially important poultry species, including turkeys, quail, guinea fowls, ducks and geese, but the main emphasis is on the domestic fowl. The overall purpose is to provide the student with an understanding of the characteristics and physiological responses of domesticated poultry, with particular reference to production. The emphasis is on modelling responses rather than on biochemical and hormonal processes. The author stresses basic concepts and models, rather than practical production systems, so that the book should have worldwide applicability. The book represents a key text for degree and advanced diploma courses in agriculture.

Their importance is also increasing in intensive feeding systems and in large farms. They are highly adaptable due to their unique feeding habits and have become popular livestock animals in a range of environments, from temperate grasslands to subtropical, semi-arid and mountainous areas. Moreover, goat milk products are finding a growing acceptance in the world market and research has increased in feeding strategies for improved productivity and quality. Examining all aspects of dairy goat feeding and nutrition, this book represents a long awaited review of recent scientific research and updated techniques. Chapters discuss aspects such as the modelling and production of goat's milk as well as the estimation of nutrient requirements and food intake of goats.

The immunologist and bestselling author Attilio Speciani dispels the cliches about so-called 'food intolerances' and guides the reader to a healthy and better relationship with food. Colitis, migraines, hormonal changes, arthritis, autoimmune diseases, imbalances of metabolism and many other disorders, from the most common to the most severe, are often related to diet. There is a close relationship between food and health, and when the natural and physiological relationship with food changes, due to food excesses or the repeated introduction of food, the organism generates measurable inflammatory signals that induce and maintain many conditions or diseases

This book is an officially authorised advisory manual that implements the recommendations on the energy and protein requirements of cattle, sheep and goats made by the AFRC Technical Committee on Responses to Nutrients (TCORN) since its establishment in 1982. TCORN has produced a series of numbered reports including No. 5 in 1990 on 'Nutrient Requirements on Ruminant Animals: Energy' and in 1992, No. 9 'Nutrient Requirements of Ruminant Animals: Protein'. The former recommended, with only minor modifications, the adoption of the AFRC's 1980 Technical Review's full recommendations on energy requirements of ruminants, while the latter recommended the adoption of a protein system based on Metabolisable Protein as the unit. Opportunity has been taken to include material from TCORN Report No. 8, 1991 on the 'Voluntary Intake of Silage by Cattle' and from an unpublished TCORN Report on the 'Nutrition of Goats'. The current volume presents these recommendations in a practical form designed for use by advisors, farmers, lecturers, research workers and students concerned with the nutrition of ruminant animals. The manual includes 45 tables of requirements (incorporating agreed safety margins) and 29 example diets.
