Book Description
Air Emissions from Animal Feeding Operations: Current Knowledge, Future Needs discusses the need for the U.S. Environmental Protection Agency to implement a new method for estimating the amount of ammonia, nitrous oxide, methane, and other pollutants emitted from livestock and poultry farms, and for determining how these emissions are dispersed in the atmosphere. The committee calls for the EPA and the U.S. Department of Agriculture to establish a joint council to coordinate and oversee short - and long-term research to estimate emissions from animal feeding operations accurately and to develop mitigation strategies. Their recommendation was for the joint council to focus its efforts first on those pollutants that pose the greatest risk to the environment and public health.
Alternative Beef Production Systems

ISBN: 9781457845574
Category : Technology & Engineering
Languages : en
Pages : 34
Book Description
Beef markets in the U.S. are rapidly changing as alternative production systems and technologies evolve in response to consumer demands and compete with conventional grain-fed beef production. Beef produced through distinguishable systems results in products with different marketable attributes that may attract price premiums, for ex., claims relating to input and other resource use, environental impacts, animal welfare, slaughter/processing infrastructure and efficiencies, and providing continuous supplies of safe products. Markets are rapidly changing as consumers demand various combinations of these attributes in their beef products and as science and consumer knowledge converge. This report explores the market outlook implications of these changes by examining the specific production technologies behind alternative production systems and products. Figures and tables. This is a print on demand report.
Global Livestock Production Systems
Author: Timothy P. RobinsonPublisher: Food & Agriculture Organization of the UN (FAO)
ISBN: 9789251070338
Category : Animal Production
Languages : en
Pages : 0
Book Description
Informed livestock sector policy development and priority setting is heavily dependent on a good understanding of livestock production systems. In a collaborative effort between the Food and Agriculture Organization and the International Livestock Research Institute, stock has been taken of where we have come from in agricultural systems classification and mapping; the current state of the art; and the directions in which research and data collection efforts need to take in the future. The book also addresses issues relating to the intensity and scale of production, moving from what is done to how it is done. The intensification of production is an area of particular importance, for it is in the intensive systems that changes are occurring most rapidly and where most information is needed on the implications that intensification of production may have for livelihoods, poverty alleviation, animal diseases, public health and environmental outcomes. A series of case studies is provided, linking livestock production systems to rural livelihoods and poverty and examples of the application of livestock production system maps are drawn from livestock production, now and in the future; livestock's impact on the global environment; animal and public health; and livestock and livelihoods. This book provides a formal reference to Version 5 of the global livestock production systems map, and to revised estimates of the numbers of rural poor livestock keepers, by country and livestock production system.

Author: Harald VoldenPublisher: Springer Science & Business Media
ISBN: 9086867189
Category : Science
Languages : en
Pages : 172
Book Description
NorFor is a semi-mechanistic feed evaluation system for cattle, which is used by advisors in Denmark, Iceland, Norway and Sweden. This book describes in detail the system and it covers five main sections. The first is concerned with information on feed characteristics, feed analysis and feed digestion methods. The second section describes the digestion and metabolism in the gastrointestinal tract and the supply and requirement of energy and metabolizable amino acids. The third section considers the prediction of feed intake and physical structure of the diet. The fourth section focuses on model evaluation and the final section provides information on the IT solutions and feed ration formulation by a non-linear economical optimization procedure. This book will be of significant interest to researchers, students and advisors of cattle nutrition and feed evaluation.
Gender in Agriculture

ISBN: 940178616X
Category : Business & Economics
Languages : en
Pages : 447
Book Description
The Food and Agriculture Organization of the United Nations (FAO) produced a 2011 report on women in agriculture with a clear and urgent message: agriculture underperforms because half of all farmers—women—lack equal access to the resources and opportunities they need to be more productive. This book builds on the report’s conclusions by providing, for a non-specialist audience, a compendium of what we know now about gender gaps in agriculture.
