This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The primary purpose of each of the subsequent chapters of this book is to promulgate quantitative approaches concerned with elucidating mechanisms in a particular area of the nutrition of ruminants, pigs, poultry, fish or pets. Given the diverse scientific backgrounds of the contributors of each chapter (the chapters in the book are arranged according to subject area), the imposition of a rigid format for presenting mathematical material has been eschewed, though basic mathematical conventions are adhered to.

Download or read book Simulation Of Beef Cattle Production Systems And Its Use In Economic Analysis written by Thomas H Spreen and published by CRC Press. This book was released on 2019-07-11 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: Economic analysis of beef cattle production has been limited by the inability to fully describe the underlying production process. Except for confined feeding of cattle, beef cattle production is the process of growing cattle who consume forages. The animal and the forage possess attributes of both factors and products of production. The production of forage constitutes one production process, animal growth is another production process, and reproduction by female animals is a third production process. Cattle production involves all three processes in such a manner that each influences the outcome of the other. Each process is itself complex and analysis is further complicated when all three are considered simultaneously.
Download or read book Livestock farming systems written by R. Rubino and published by BRILL. This book was released on 2023-08-28 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2019-01-14 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to build consensus on methods to measure and model soil carbon stocks and stock changes, the Steering Committee of the Livestock Environmental Assessment and Performance (LEAP) Partnership mandated a task force to develop this scoping analysis and pave the way towards the formation of the LEAP Tecnical Advisory Group on soil carbon stock changes. Soil carbon sequestration and storage in grasslands offers a significant potential to compensate for GHG emissions from livestock, but the lack of consensus on the appropriate methodologies to account for soil carbon stock changes hinders robust and standardized assessments. In this report, we reviewed several published soil organic carbon (SOC) models, and evaluated their aptitude to combine them with life cycle assessments (LCAs). Among contentious issues, the most relevant are: a) the lack of universal models, b) the uneven data availability, comparability and quality between countries and regions, and c) the difficulty to match measurable SOC fractions with those determined by the models. Taking this into account, a tiered approach is proposed, according to the availability of original data to run the models. The use of IPCC carbon (C) accounting system appears to be the simplest approach suitable to countries with scarcity of original C data. Conversely, more complex models such as Century (Parton 1987, 1988) or Roth C (Smith 1998) are likely to perform better and give less uncertainty when original input data are easily available.

Download or read book Livestock Farming Systems in Central and Eastern Europe written by A. Gibon and published by BRILL. This book was released on 2023-08-28 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines the potential of Livestock Farming Systems (LFS) research to assess and understand the diversity of livestock farming systems in Central and Eastern Europe (CEE). LFS research based on systemic modelling has improved the understanding of livestock production realities at farm level and influenced agricultural development strategies in Western Europe. Researchers from both Western and Eastern Europe carried out this initial study, which was coordinated and sponsored under a collaborative agreement between EAAP and FAO, and was run in selected regions in Bulgaria, the Czech Republic, Hungary, Poland and the Slovak Republic. The results and conclusions of the study are reported in the book, together with the other contributions of interest with respect to the sustainable development of livestock production in CEE presented and discussed during a workshop in Budapest in August 2001. The results of the study demonstrate the adaptability of LFS research to systems predominantly based on large-scale private, corporate and co-operative farms in the CEE countries.
