This book was released on 1995 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditional season-long livestock grazing strategy on western riparian areas has been identified as one of the factors affecting rangeland productivity as well as wildlife habitat in riparian zones. As alternatives to summer season-long grazing, summer short-duration grazing (without haying), and fall short-duration grazing (following haying), were considered in this study to determine their effects on ranch production and profitability. Five grazing plans for the case ranch were evaluated. A planning period of six years (1993-98) was used for each plan. The present values (PVs) of net returns, using a 7 percent discount rate, were positive for all the plans. Shifting from summer season-long grazing to plans with summer short-duration grazing reduced the PVs of net returns by 13 percent, on average. Reasons for reductions in net returns included i) higher labor as well as fencing costs, ii) downward adjustment of herd size, and iii) increased overhead costs per animal. Shifting from summer season-long to fall short-duration grazing, in contrast, increased the PVs of net returns by 7-9 percent. But this system of grazing involved 1) a large haying costs, and ii) a higher management requirement. Although research results showed a difference in profitability between the three grazing strategies, the differences can be viewed as evidence for "tendency" only. This is so because those differences were so small and so sensitive to changes in some parameters (i.e., changes of magnitudes which are smaller than the measurement error) that they cannot be viewed as significantly different. Recognizing non-pecuniary goals of the ranchers, economic sustainability was determined by the criterion that the rate of return on ranch investment, on a long-term basis, is at least 3 percent (one-half of the opportunity cost of capital as measured by the annual yield rate on 10-year U.S. Treasury notes). The rate of return on ranch investment, on average, was 3 percent. Thus, the ranch operation was found economically sustainable under all grazing systems examined. However, if public land grazing permit was reduced by 30 percent, then returns to investment, on average, fell to 2.5 percent, signalling that ranchers no longer were economically sustainable (based on the aforementioned criterion). The study results indicated that grazing strategies correlate with the structure of the riparian habitat. Fall short-duration grazing may be most compatible with a riparian habitat structure that is generally viewed as being ecologically more desirable than other forms of habitat structure. However, some plants, bird, and mammal species preferred the habitat structure correlated with other grazing strategies. Thus, from that perspective, a mixture of grazing strategies (provided they are determinants of vegetation structure) is, at the landscape level, more desirable than a single uniform grazing strategy for encouraging species diversity.

Available in PDF, EPUB and Kindle. Book excerpt: New Aspects of Meat Quality, Second Edition continues to be the leading source of scientific information for what constitutes meat quality for consumers, marketers and producers in the 21st century. The book includes traditional measures of meat quality such as texture, water holding, color, flavor/aroma, safety/microbiology and processing characteristics as well as quality assurance schemes, organic/free range, ethical meat production, and the desirability of genetically modified organisms, amongst others. Users will find comprehensive coverage on developments in our understanding of how muscle structure affects the eating qualities of cooked meat, along with techniques for measuring, predicting and producing meat quality. In addition, the book covers how these new techniques help us minimize variability in eating quality and/or maximize value. The book's final section identifies the current qualities of consumer and public perceptions and what is sustainable, ethical, desirable and healthy in meat production and consumption. Provides the latest research techniques and developments presented by top researchers in the field Covers new aspects of meat quality with the same scientific authority as texts on traditional meat quality value Includes five new chapters that cover the role of proteolysis, meat flavor, meat bi-products, and meat and public health

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2015-03-31 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume addresses in detail both livestock’s role in climate change and the impacts of climate change on livestock production and reproduction. Apart from these cardinal principles of climate change and livestock production, this volume also examines the various strategies used to mitigate livestock-related GHG emissions, and those which can reduce the impacts of climate change on livestock production and reproduction. Presenting information and case studies collected and analyzed by professionals working in diversified ecological zones, the book explores the influence of climate change on livestock production across the globe. The most significant feature of this book is that it addresses in detail the different adaptation strategies and identifies targets for different stakeholders in connection with climate change and livestock production. Further, it puts forward development plans that will allow the livestock industries to cope with current climate changes and strategies that will mitigate the effects by 2025. Lastly, it provides researchers and policymakers several researchable priorities to help develop economically viable solutions for livestock production with less GHG emissions, promoting a cleaner environment in which human beings and livestock can live in harmony without adverse effects on productivity. Given that livestock production systems are sensitive to climate change and at the same are themselves a contributor to the phenomenon, climate change has the potential to pose an increasingly formidable challenge to the development of the livestock sector. However, there is a dearth of scientific information on adapting livestock production to the changing climate; as such, well-founded reference material on sustaining livestock production systems under the changing climate scenarios in different agro-ecological zones of the world is essential. By methodically and extensively addressing all aspects of climate change and livestock production, this volume offers a valuable tool for understanding the hidden intricacies of climatic stress and its influence on livestock production.
