Recent Advances in Animal Nutrition 1990 focuses on technologies and controls needed to ensure meat quality. The book first discusses allergic responses to diets in humans. Changes in meat consumption and consumer attitudes; improving the quality of meat; and implications for the future are described. The text looks at legislation and its effect on the feed compounder, including marketing of feeds, medicated feeds, bovine spongiform encephalopathy (BSE), and safety regulations. The book also underscores the control of feed-born bacterial and viral pathogens in farm animals. Animal infections and diseases connected with feeds; control measures during manufacture of feeds; and public health implications are noted. The text also discusses chemical probiosis, effects of mycotoxins on animal performance, and nutritive value of wheat and its effect on broiler performance. The book then focuses on water requirement of growing-finishing pigs. Water input/output relationships in pigs; factors affecting the relative contribution of different water losses/uses; and factors affecting the supply of water to pigs are described. The text also discusses water requirement of poultry, piglets, and lactating cows. The book is a valuable source of data for readers interested in studying the controls and technologies needed to improve meat quality.
The science of animal nutrition has made significant advances in the past century. In looking back at the discoveries of the 20th century, we can appreciate the tremendous impact that animal nutrition has had on our lives. From the discovery of vitamins and the sweeping shift in the use of oilseeds to replace animal products as dietary protein sources for animals during the war times of the 1900s-to our integral understanding of nutrients as regulators of gene expression today-animal nutrition has been the cornerstone for scientific advances in many areas. At the milestone of their 70th year of service to the nation, the National Research Council's (NRC) Committee on Animal Nutrition (CAN) sought to gain a better understanding of the magnitude of recent discoveries and directions in animal nutrition for the new century we are embarking upon. With financial support from the NRC, the committee was able to organize and host a symposium that featured scientists from many backgrounds who were asked to share their ideas about the potential of animal nutrition to address current problems and future challenges.
Authored by international experts in the animal-production industry, this record of the proceedings of the 42nd University of Nottingham Feed Conference explores topics such as the improvements of feed efficiency, the impact of biofuel co-products, the use of enzymes to increase nutritive value, and the techniques for coping with disease outbreaks. Filled with comprehensive analyses of the issues as well as practical applications, this is an essential read for researchers, consultants, animal science students, legislators, and practitioners. The newest volume in the series, this detailed account contains the most recent information in the livestock industry.
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 preparationâ€"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.
By 2050 the world's population is projected to grow by one-third, reaching between 9 and 10 billion. With globalization and expected growth in global affluence, a substantial increase in per capita meat, dairy, and fish consumption is also anticipated. The demand for calories from animal products will nearly double, highlighting the critical importance of the world's animal agriculture system. Meeting the nutritional needs of this population and its demand for animal products will require a significant investment of resources as well as policy changes that are supportive of agricultural production. Ensuring sustainable agricultural growth will be essential to addressing this global challenge to food security. Critical Role of Animal Science Research in Food Security and Sustainability identifies areas of research and development, technology, and resource needs for research in the field of animal agriculture, both nationally and internationally. This report assesses the global demand for products of animal origin in 2050 within the framework of ensuring global food security; evaluates how climate change and natural resource constraints may impact the ability to meet future global demand for animal products in sustainable production systems; and identifies factors that may impact the ability of the United States to meet demand for animal products, including the need for trained human capital, product safety and quality, and effective communication and adoption of new knowledge, information, and technologies. The agricultural sector worldwide faces numerous daunting challenges that will require innovations, new technologies, and new ways of approaching agriculture if the food, feed, and fiber needs of the global population are to be met. The recommendations of Critical Role of Animal Science Research in Food Security and Sustainability will inform a new roadmap for animal science research to meet the challenges of sustainable animal production in the 21st century.
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.
In recent years the gastrointestinal microflora has featured strongly in scientific, veterinary and medical research. As a result it has become obvious that the gut microflora is an essential component of the healthy animal. Not only is it involved in digestion of food, it is essential for the optimal resistance to disease. The first part of this book records the research that has been done on the factors affecting colonization of the gut and the effect that the flora has on the host animal. The second part discusses the way in which this basic knowledge affects the choice of organism being used as a probiotic. The evidence for the involvement of the gut microflora in the health and well-being of the animal is incontrovertible, but the development of probiotics has been largely empirical, failing to capitalize on the relevant research data. The bringing together of the basic information on gut microecology and the development of probiotic preparations is long overdue. It is hoped that this exercise will result in a more scientific approach to probiotic development and the emergence of new and improved preparations for animals and man. The authors involved are all experts in their field and I am greatly indebted to them for their contributions to the book. R. Fuller Abbreviations used for - generIc names Aspergillus A.B.
