Book Description
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.

Book Description
This book is intended to be a companion volume to 'Protein Nutrition in Ruminants' (1982, Academic Press), which emphasized both the role of proteins and new systems for their evaluation. Here the focus is on energy-yielding nutrients and problems involved in evaluating them. Nonetheless in both volumes there is explicit recognition of the interdependence of energy and protein nutrition. I have not attempted to review comprehensively all the literature relating to ruminant energy nutrition and must apologize to colleagues whose work is not fully reported. Where possible tables and figures are taken from the studies of our group at the Rowett Research Institute since, if for no other reason, I am most familiar with these data. I have first considered the nutrition of the newborn and have stressed the role of behaviour 'in determining whether nutrients enter or bypass the rumen. The development of the rumen, the of anaerobic fermentation and the roles of various principles . species of rumen bacteria, protozoa and fungi in relation to different substrates, are summarized. This is followed by accounts of the factors affecting the utilization of different substrates and the v vi Preface absorption and metabolism of the end-products of fermentation and digestion, together with estimates of digestive capacity in various segments of the gut. The ruminant's requirements for energy-yielding nutrients is considered in relation to the per formance of various activities and to environmental conditions, particular attention being paid to the requirement for glucose precursors.

Book Description
This book is an officially authorized 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: Energyand 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.

Book Description
As members of the public becomes more concious of the food they consume and its content, higher standards are expected in the preparation of such food. The updated seventh edition of Nutrient Requirements of Beef Cattle explores the impact of cattle's biological, production, and environmental diversities, as well as variations on nutrient utilization and requirements. More enhanced than previous editions, this edition expands on the descriptions of cattle and their nutritional requirements taking management and environmental conditions into consideration. The book clearly communicates the current state of beef cattle nutrient requirements and animal variation by visually presenting related data via computer-generated models. Nutrient Requirements of Beef Cattle expounds on the effects of beef cattle body condition on the state of compensatory growth, takes an in-depth look at the variations in cattle type, and documents the important effects of the environment and stress on food intake. This volume also uses new data on the development of a fetus during pregnancy to prescribe nutrient requirements of gestating cattle more precisely. By focusing on factors such as product quality and environmental awareness, Nutrient Requirements of Beef Cattle presents standards and advisements for acceptable nutrients in a complete and conventional manner that promotes a more practical understanding and application.

Book Description
In the past decade, animal scientists have learned that administering recombinantly derived somatotropin (growth hormone) to cows improves milk production and that giving beta-adrenergic agonists to meat animals improves productivity and leanness. In order for these metabolic modifiers to yield benefits, however, sound management of the animals' nutrition is necessary. This volume reports on how these substances work in the animals' metabolism, what effects they might have on nutrient requirements of domestic livestock, and what information should be developed further by investigators. The book explores the current understanding of the biology, structure, mechanisms of action, and treatment effects of somatotropin, beta-adrenergic agonists, and anabolic steroids. A companion volume to the Nutrient Requirements of Domestic Animals series, this authoritative volume will be required reading for animal scientists, researchers, veterinarians, livestock farmers, and faculty and students in university animal veterinary science programs.

Book Description
Ruminant animals are the most important source of meat and milk consumed by humans. In addition, they do not need to compete with humans for food but can thrive on feed unsuitable for monogastric animals. The particular nature of ruminant digestion and the special role played by the rumen micro-organisms involves an extra dimension of complexity compared with other mammals. Feeding ruminants is, at least in part, the process of feeding the complex community of microorganisms of all types that inhabit the rumen. The interplay between the members of this community and their host is not only of great intrinsic interest, but of vital importance if the world's ruminants are to be fed and managed to give the best results. Particular progress has been made in the last decade in the understanding of rumen fungi and their role in digestion. New methods of measuring amino acid requirements have also been developed and led to some interesting observations in this respect. Improved studies of urea recycling and the measurement of purine excretion have enabled better estimates of rumen microbial protein production, as well as progress in how to manipulate fat stores in ruminants via protein supply. In the Second Edition of his book, Dr. Orskov brings this subject up to date, providing both a comprehensive reference and an invaluable primer for advanced students and research scientists in animal nutrition and husbandry. Particular attention has been paid to management systems able to put this new knowledge to work in practical situations.
