"This book deals with trace elements, such as cobalt, copper, iron, manganese, selenium and zinc which are essential to modern animal nutrition, but are increasingly detrimental to soil and water quality in today's globalized production. The goal in finding a sustainable balance between trace element use in animal nutrition and its impact on the environment is addressed by focussing on the following questions: - What is the trace element flow on farm, regional or national scale and which tools are available to influence the flow? - What are today's and future soil and water quality in regards to trace minerals? - What are the trace mineral loading limits in soil and water from a health and legal standpoint? - Which technologies exist to modify slurry trace element contents? - What is today's knowledge on quantitative and qualitative trace element requirements and recommended supplementation for ruminants, swine, poultry, fish and crustaceans? - What is trace element bioavailability and how can it be determined? - To which extent are trace minerals related to immune response? - What are the future issues to be addressed in trace element nutrition? This book contains the peer-reviewed papers of the first International Symposium on Trace Elements in Animal Production Systems. It is a valuable resource for researchers and professionals in the life sciences of animal nutrition, soil and water quality, for actors in the feed industry and policy making."

Livestock farming increasingly means much more than just food production and product quality is no longer simply synonymous with food safety and the provision of energy and protein nutrients. This book examines the variety of reasons for this shift in thinking and provides a basis for a new approach to livestock farming systems. The topical issues for product quality based on local resources are addressed from a variety of angles, including genomics, land use, the consumer preference and human nutrition. The book focuses on the following topics, using examples from all over the world: the current change in views and values on quality of animal products; the specificity of traditional dairy and meat products and the technology of processing; the role of local breeds and traditional livestock farming systems in today’s society; the search for local avenues for sustainable development of livestock farming systems. The book serves as a reference point for scientists, practitioners in the livestock industry, teachers and students in animal sciences, national and international institutions and policy-makers. It is of interest to all those who wish to gain an overview of the current challenges in the establishment of priorities and the search for operational solutions for animal production development, while at the same time considering the benefit to consumers, the environment and local economies.

The rapidly changing nature of animal production systems, especially increasing intensification and globalization, is playing out in complex ways around the world. Over the last century, livestock keeping evolved from a means of harnessing marginal resources to produce items for local consumption to a key component of global food chains. Livestock in a Changing Landscape offers a comprehensive examination of these important and far-reaching trends. The books are an outgrowth of a collaborative effort involving international nongovernmental organizations including the United Nations Food and Agriculture Organization (UN FAO), the International Livestock Research Institute (ILRI), the Swiss College of Agriculture (SHL), the French Agricultural Research Centre for International Development (CIRAD), and the Scientific Committee for Problems of the Environment (SCOPE). Volume 1 examines the forces shaping change in livestock production and management; the resulting impacts on landscapes, land use, and social systems; and potential policy and management responses. Volume 2 explores needs and draws experience from region-specific contexts and detailed case studies. The case studies describe how drivers and consequences of change play out in specific geographical areas, and how public and private responses are shaped and implemented. Together, the volumes present new, sustainable approaches to the challenges created by fundamental shifts in livestock management and production, and represent an essential resource for policy makers, industry managers, and academics involved with this issue.
