Book Description
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.

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
This book contains an up to date and more focused examination of developments in the understanding of voluntary food intake and new ideas and studies related to diet selection. New chapters are introduced and old ones are rewritten and reorganized in a more readable style by using extensive reference to books and reviews. The book is intended for animal nutritionists, animal scientists, farm owners and managers, veterinarians and students.

Book Description
This book is developed from a British Society of Animal Science occasional meeting, held in September 2000. It brings together all of the scientific disciplines involved in the pre- and post-weaning biology of the piglet, concentrating on growth/development, nutrition, immunology/health, ethology and the physical environment.

Book Description
This monumental text-reference places in clear persepctive the importance of nutritional assessments to the ecology and biology of ruminants and other nonruminant herbivorous mammals. Now extensively revised and significantly expanded, it reflects the changes and growth in ruminant nutrition and related ecology since 1982. Among the subjects Peter J. Van Soest covers are nutritional constraints, mineral nutrition, rumen fermentation, microbial ecology, utilization of fibrous carbohydrates, application of ruminant precepts to fermentive digestion in nonruminants, as well as taxonomy, evolution, nonruminant competitors, gastrointestinal anatomies, feeding behavior, and problems fo animal size. He also discusses methods of evaluation, nutritive value, physical struture and chemical composition of feeds, forages, and broses, the effects of lignification, and ecology of plant self-protection, in addition to metabolism of energy, protein, lipids, control of feed intake, mathematical models of animal function, digestive flow, and net energy. Van Soest has introduced a number of changes in this edition, including new illustrations and tables. He places nutritional studies in historical context to show not only the effectiveness of nutritional approaches but also why nutrition is of fundamental importance to issues of world conservation. He has extended precepts of ruminant nutritional ecology to such distant adaptations as the giant panda and streamlined conceptual issues in a clearer logical progression, with emphasis on mechanistic causal interrelationships. Peter J. Van Soest is Professor of Animal Nutrition in the Department of Animal Science and the Division of Nutritional Sciences at the New York State College of Agriculture and Life Sciences, Cornell University.

Book Description
This report follows up on an interim report released in February 2004 that focused on immediate needs in the areas of animal care and management, recordkeeping, and pest control. The report finds that the zoo has made good-faith efforts to correct deficiencies noted in the interim report and has made some noticeable improvements in the past year in zoo operations and animal care. However, problems in areas such as staff training, workplace culture, and strategic planning still need to be addressed. Specifically, the report recommends that the zoo immediately develop and implement animal-care training programs to ensure that people who are directly responsible for the well-being of its animal collection are adequately prepared and competent. The report commends a zoo-initiated strategic planning process as a positive step, but recommends it contain a more detailed, comprehensive strategy of how it will meet short-term goals and that it should link plans to upgrade facilities with those to acquire animals. The zoo should also focus on improving communication among keepers, veterinarians, nutritionists, senior managers, and curators.

Book Description
Genetic-based animal biotechnology has produced new food and pharmaceutical products and promises many more advances to benefit humankind. These exciting prospects are accompanied by considerable unease, however, about matters such as safety and ethics. This book identifies science-based and policy-related concerns about animal biotechnologyâ€"key issues that must be resolved before the new breakthroughs can reach their potential. The book includes a short history of the field and provides understandable definitions of terms like cloning. Looking at technologies on the near horizon, the authors discuss what we know and what we fear about their effectsâ€"the inadvertent release of dangerous microorganisms, the safety of products derived from biotechnology, the impact of genetically engineered animals on their environment. In addition to these concerns, the book explores animal welfare concerns, and our societal and institutional capacity to manage and regulate the technology and its products. This accessible volume will be important to everyone interested in the implications of the use of animal biotechnology.
