The tenth edition of this essential reference presents new knowledge about the nutritional needs of swine that consider such factors as growth rate, carcass leanness, gender, health, environment, and repartitioning agents. New sections are presented on requirements for amino acids and other nutrients. In addition, an original modeling approach to arriving at energy and amino acid needs for given animals is incorporated in this revision. The book comes with a CD-ROM that allows users to create tables of nutrient requirements for swine of a specific body weight and level of productivity. Nutrient Requirements of Swine covers: Biological concepts that underlie nutrient needs for growth and function. New data on amino acid and energy requirements and the factors that shape them. New findings on lysine and the bioavailability of amino acids. New research results on minerals and vitamins. Nutrient composition of an expanded list of feedstuffs. The role of water in swine physiology, including factors that affect the quality of drinking water. Expanded tables of feed ingredients and their nutrient composition provide bioavailability estimates, fatty acid composition of fats typically used in swine diets, and important information on estimating the amino acid content of crude protein.

How much do animals eat? Why do eating patterns change? How do physiological, dietary, and environmental factors affect feed intake? This volume, a comprehensive overview of the latest animal feed intake research, answers these questions with detailed information about the feeding patterns of fishes, pigs, poultry, dairy cows, beef cattle, and sheep. Equations for calculating predicted feed intake are presented for each animal and are accompanied by charts, graphs, and tables.
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.
Updating recommendations last made by the National Research Council in the mid-1980s, this report provides nutrient recommendations based on physical activity and stage in life, major factors that influence nutrient needs. It looks at how nutrients are metabolized in the bodies of dogs and cats, indications of nutrient deficiency, and diseases related to poor nutrition. The report provides a valuable resource for industry professionals formulating diets, scientists setting research agendas, government officials developing regulations for pet food labeling, and as a university textbook for dog and cat nutrition. It can also guide pet owners feeding decisions for their pets with information on specific nutrient needs, characteristics of different types of pet foods, and factors to consider when feeding cats and dogs.
Abstract: A comprehensive, authoritative report of a National Research Council subcommittee reviews current knowledge concerning selenium (Se) in nutrition for nutrition, food, and health professionals. The report focuses on: the chemistry of Se and its analysis; Se distribution in soils, plants, animal feeds, human foods, and water; the Se cycle in nature; biochemical functions of Se (e.g., associations with glutathione peroxidase; nutritional and metabolic inter-associations); Se dietary forms and its absorption, transport, retention, distribution, and metabolism; Se nutritional aspects (dietary requirements and deficiencies in animals, and role in human nutrition); the toxic effects of excess Se; and the effects of high and low Se exposures in human health. A summary of the findings of this report and an extensive list of literature references cited are appended. (wz).
This Web site is an electronic version of the book Nutrient requirements of mink and foxes, revised by the Board on Agriculture in 1982. Visitors can get information on these fur-bearing species and discover why foxes were raised commercially earlier than mink and what nutritional requirements are needed for commercial coat value. Much of the information that is available relates to the growth period for young and pelted mink.
Many feedstuffs and forages do not provide the dietary vitamins necessary for optimum growth and development, making supplementation necessary. This volume offers a practical, well-organized guide to safe levels of vitamin supplementation in all major domestic species, including poultry, cattle, sheep, and fishes. Fourteen essential vitamins are discussed with information on requirements in various species, deficiency symptoms, metabolism, indications of hypervitaminosis, and safe dosages.
In the years since the third edition of this indispensable reference was published, a great deal has been learned about the nutritional requirements of common laboratory species: rat, mouse, guinea pig, hamster, gerbil, and vole. The Fourth Revised Edition presents the current expert understanding of the lipid, carbohydrate, protein, mineral, vitamin, and other nutritional needs of these animals. The extensive use of tables provides easy access to a wealth of comprehensive data and resource information. The volume also provides an expanded background discussion of general dietary considerations. In addition to a more user-friendly organization, new features in this edition include: A significantly expanded section on dietary requirements for rats, reporting substantial new findings. A new section on nutrients that are not required but that may produce beneficial results. New information on growth and reproductive performance among the most commonly used strains of rats and mice and on several hamster species. An expanded discussion of diet formulation and preparation--including sample diets of both purified and natural ingredients. New information on mineral deficiency and toxicity, including warning signs. This authoritative resource will be important to researchers, laboratory technicians, and manufacturers of laboratory animal feed.
