Book Description
How we produce and consume food has a bigger impact on Americans' well-being than any other human activity. The food industry is the largest sector of our economy; food touches everything from our health to the environment, climate change, economic inequality, and the federal budget. From the earliest developments of agriculture, a major goal has been to attain sufficient foods that provide the energy and the nutrients needed for a healthy, active life. Over time, food production, processing, marketing, and consumption have evolved and become highly complex. The challenges of improving the food system in the 21st century will require systemic approaches that take full account of social, economic, ecological, and evolutionary factors. Policy or business interventions involving a segment of the food system often have consequences beyond the original issue the intervention was meant to address. A Framework for Assessing Effects of the Food System develops an analytical framework for assessing effects associated with the ways in which food is grown, processed, distributed, marketed, retailed, and consumed in the United States. The framework will allow users to recognize effects across the full food system, consider all domains and dimensions of effects, account for systems dynamics and complexities, and choose appropriate methods for analysis. This report provides example applications of the framework based on complex questions that are currently under debate: consumption of a healthy and safe diet, food security, animal welfare, and preserving the environment and its resources. A Framework for Assessing Effects of the Food System describes the U.S. food system and provides a brief history of its evolution into the current system. This report identifies some of the real and potential implications of the current system in terms of its health, environmental, and socioeconomic effects along with a sense for the complexities of the system, potential metrics, and some of the data needs that are required to assess the effects. The overview of the food system and the framework described in this report will be an essential resource for decision makers, researchers, and others to examine the possible impacts of alternative policies or agricultural or food processing practices.

Book Description
Commercial Chicken Meat and Egg Production is the 5th edition of a highly successful book first authored by Dr. Mack O. North in 1972, updated in 1978 and 1984. The 4th edition was co-authored with Donald D. Bell in 1990. The book has achieved international success as a reference for students and commercial poultry and egg producers in every major poultry producing country in the world. The 5th edition is essential reading for students preparing to enter the poultry industry, for owners and managers of existing poultry companies and for scientists who need a major source of scientifically based material on poultry management. In earlier editions, the authors emphasized the chicken and its management. The 5th edition, with the emphasis shifted to the commercial business of managing poultry, contains over 75% new material. The contributions of 14 new authors make this new edition the most comprehensive such book available. Since extensive references are made to the international aspects of poultry management, all data are presented in both the Imperial and Metric form. Over 300 tables and 250 photos and figures support 62 chapters of text. New areas include processing of poultry and eggs with thorough discussions of food safety and further processing. The business of maintaining poultry is discussed in chapters on economics, model production firms, the use of computers, and record keeping. Updated topics include: breeders and hatchery operations; broiler and layer flock management; replacement programs and management of replacements; nutrition; and flock health. New chapters address flock behavior, ventilation, waste management, egg quality and egg breakage. Other new features include a list of more than 400 references and a Master List of the tables, figures, manufacturers of equipment and supplies, research institutions, books and periodicals, breeders, and trade associations. Commercial growers will find the tables of data of particular interest; scientists will be able to utilize the extensive references and to relate their areas of interest to the commercial industry's applications; and students will find that the division of the book into 11 distinct sections, with multiple chapters in each, will make the text especially useful.

Book Description
Tropical Layer Chicken Management Guide is designed to provide the layer-grower a broader understanding of the impact of animal production on our social and economic environment as well as methods to reduce its footprint on our physical environment. In other words, the layer-grower will explore ways to be sustainable using local feed resources, renewable energy and integrating different agricultural production systems.
