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.

This new release presents the wealth of information gleaned about nonhuman primates nutrition since the previous edition was published in 1978. With expanded coverage of natural dietary habits, gastrointestinal anatomy and physiology, and the nutrient needs of species that have been difficult to maintain in captivity, it explores the impact on nutrition of physiological and life-stage considerations: infancy, weaning, immune function, obesity, aging, and more. The committee also discusses issues of environmental enrichment such as opportunities for foraging. Based on the world's scientific literature and input from authoritative sources, the book provides best estimates of nutrient requirements. The volume covers requirements for energy: carbohydrates, including the role of dietary fiber; proteins and amino acids; fats and fatty acids; minerals, fat-soluble and water-soluble vitamins; and water. The book also analyzes the composition of important foods and feed ingredients and offers guidelines on feed processing and diet formulation.

Updating two previous National Research Council publications, Nutrient Requirements of Sheep, Sixth Revised Edition, 1985, and Nutrient Requirements of Goats, First Edition, 1981, this new book provides an evaluation of the scientific literature on the nutrient requirements of small ruminants in all stages of life. In addition, effects of the environment, feed additives, and metabolism modifiers on nutrient requirements are addressed. Proper formulation of diets for small ruminants depends on adequate knowledge of their nutrient requirements. These requirements depend on the breed and age of the animal and whether he or she is exercising, pregnant, or lactating. Nutrient Requirements of Small Ruminants brings together a summary of this latest data with new and expanded information on the composition of feeds commonly consumed by small ruminants, both domestic and wild. For the first time this authoritative reference work includes information on cervids and camelids. Primarily intended for animal nutritionists, veterinarians, and other scientists, some sections will be useful to individual sheep and goat owners and managers and to those responsible for the care and management of wildlife species. As both a practical and a technical reference book, this material is written to ensure that diets of small ruminants contain adequate amounts of nutrients and that intakes of certain nutrients are not so excessive that they inhibit performance or impair health.

Since their inception in 1862, the U.S. land grant colleges have evolved to become the training ground for the nation's and the world's agriculturists. In this book, the committee examines the future of the colleges of agriculture in light of changing national priorities for the agricultural, food, and natural resource system. The effects of federal funding constraints also are examined, as are opportunities for growth presented by developments in science. The committee's preceding volume, Colleges of Agriculture at the Land Grant Universities: A Profile, is a compilation of the data that helped formulate the specific questions to be addressed. Colleges of Agriculture at the Land Grant Univerisities: Public Service and Public Policy is the deliberative report, rating conclusions and recommendations for institutional innovation and public policy. It addresses these and other questions: What education mission should colleges of agriculture adopt--and what strategies should they use--in light of significant changes in the agricultural complex? Research in agriculture is expected to respond to consumer demands, environmental concerns, world population growth, and increasing pressure on agricultural lands. Is the century-old structure of land grant university-based research up to the task? What is the role of extension in light of today's smaller farming communities and larger farming conglomerates? This volume is the culmination of a landmark evaluation of land grant colleges of agriculture, an American institution. This document will be of value to policymakers, administrators, and others involved in agricultural science and education.

Rain forests are rapidly being cleared in the humid tropics to keep pace with food demands, economic needs, and population growth. Without proper management, these forests and other natural resources will be seriously depleted within the next 50 years. Sustainable Agriculture and the Environment in the Humid Tropics provides critically needed direction for developing strategies that both mitigate land degradation, deforestation, and biological resource losses and help the economic status of tropical countries through promotion of sustainable agricultural practices. The book includes A practical discussion of 12 major land use options for boosting food production and enhancing local economies while protecting the natural resource base. Recommendations for developing technologies needed for sustainable agriculture. A strategy for changing policies that discourage conserving and managing natural resources and biodiversity. Detailed reports on agriculture and deforestation in seven tropical countries.

How can the United States meet demands for agricultural production while solving the broader range of environmental problems attributed to farming practices? National policymakers who try to answer this question confront difficult trade-offs. This book offers four specific strategies that can serve as the basis for a national policy to protect soil and water quality while maintaining U.S. agricultural productivity and competitiveness. Timely and comprehensive, the volume has important implications for the Clean Air Act and the 1995 farm bill. Advocating a systems approach, the committee recommends specific farm practices and new approaches to prevention of soil degradation and water pollution for environmental agencies. The volume details methods of evaluating soil management systems and offers a wealth of information on improved management of nitrogen, phosphorus, manure, pesticides, sediments, salt, and trace elements. Landscape analysis of nonpoint source pollution is also detailed. Drawing together research findings, survey results, and case examples, the volume will be of interest to federal, state, and local policymakers; state and local environmental and agricultural officials and other environmental and agricultural specialists; scientists involved in soil and water issues; researchers; and agricultural producers.

Eine kurze Geschichte der Menschheit

Krone der Schöpfung? Vor 100 000 Jahren war der Homo sapiens noch ein unbedeutendes Tier, das unauffällig in einem abgelegenen Winkel des afrikanischen Kontinents lebte. Unsere Vorfahren teilten sich den Planeten mit mindestens fünf weiteren menschlichen Spezies, und die Rolle, die sie im Ökosystem spielten, war nicht größer als die von Gorillas, Libellen oder Quallen. Vor 70 000 Jahren dann vollzog sich ein mysteriöser und rascher Wandel mit dem Homo sapiens, und es war vor allem die Beschaffenheit seines Gehirns, die ihn zum Herren des Planeten und zum Schrecken des Ökosystems werden ließ. Bis heute hat sich diese Vorherrschaft stetig zugespitzt: Der Mensch hat die Fähigkeit zu schöpferischem und zu zerstörerischem Handeln wie kein anderes Lebewesen. Anschaulich, unterhaltsam und stellenweise hochkomisch zeichnet Yuval Harari die Geschichte des Menschen nach und zeigt alle großen, aber auch alle ambivalenten Momente unserer Menschwerdung.

Dieses Buch wird als Atlas bezeichnet, nicht als Lehrbuch. Wir nehmen an, daß sein Benutzer Zugang zum Inhalt der Standardwerke theoretischer und praktischer Hämatologie hat. Wir haben daher nicht die Absicht, deren Dar legungen zu wiederholen. Wir sind der festen Uberzeugung, daß es keinen Ersatz für eigene Bemühungen um mikroskopische Präparate gibt. um Ver ständnis für die hämatologische Zytologie zu gewinnen, aber wir sind ebenfalls überzeugt, daß eine Sammlung von Farbmikrophotos eine nutzliche Ergänzung solcher mikroskopischer Studien darstellen kann. Es existieren gute Atlanten der Hämatologie, aber es besteht Bedarf für einen nicht zu umfangreichen Band von ausgezeichneten Mikrophotos üblicher Große, die eine praktische Hilfe für den täglichen Gebrauch am Mikroskopiertisch sind. Dies zu erreichen war unsere Absicht. Die Abbildungen zeigen Beispiele der meisten Zelltypen, auf die man üblicherweise stoßt. und einige, die seltener sind, aber wir haben eine ein seitige Darstellung von Seltenheiten vermieden. Wir haben auch keine Auswahl von überscharfen photogenen Ausschnitten getroffen, da unser Objektiv eher der Wirklichkeit als der Perfektion folgte. Wir beurteilen die Verschiedenheit in Färbung und Hintergrund unter der Sammlung von Aufnahmen nicht als praxis feindlich, sondern als Hilfe beim Abschätzen der farberischen Variationen, die bei den meisten Färbemethoden im Liblichen Laboratorium eingeschlossen sind.
