Book Description
Annual grazing practices are highly variable among farms as constantly changing plant and animal interactions influence forage quality and utilization. Traditional continuous grazing practices utilize about 30 percent of the available forage while management-intensive grazing practices may utilize more than 70 percent. Data collected at the University of Missouri, Forage Systems Research Center (FSRC), Linneus, Missouri was used to conduct this study; it shows animal performance and stocking rates of different systems listed below. A ten year, capital budgeting model was developed to compare technical efficiency to economic efficiency of annual grazing systems. This assessment was based on three grazing technologies, named for the required management intensity level--High, Medium and Low. Also considered were three types of farming systems: Specialized, Diversified and Part-time. When merged, nine combinations of commercial cow-calf technologies and production levels were created. Once the FSRC baseline model was assessed, three technical parameters fixed by system design were relaxed--(1) removal of the steers from the system (NOSTR), (2) changing the ratio of winter to summer acreage (WSR), and (3) standardizing cow conception rates among systems. An assessment of the economic performance of the FSRC and NOSTR systems revealed the two systems to be comparable with respect to investment rates of return. When alternative management levels were compared (for both systems), returns were highest for Medium, High and Low levels, respectively. When system parameters were changed (WSR and conception rates) the result was a new economic ranking with the High management system ranked first, followed by Medium and Low level alternatives. However, the difference in economic returns between High and Medium levels is inconsequential, and one can conclude there was no difference in the economic performance of the two systems. Risk considerations (higher investment outlays associated with High management level) would result in ranking the Medium level as the best system from an economic perspective. Additional research is warranted using different animal prices and different system parameters--forage species, stocking rates, winter/summer acreage relationships, etc.

Book Description
Continuous and rotational grazing systems are two of the most frequently employed grazing systems in the western United States. Years of scientific evidence suggests that continuous grazing frequently outperforms rotational grazing in regard to cattle production. In this study we use economic data from a long-term USDA-ARS study in northern Colorado to determine if there are profit differences that may influence a producer’s decision to adopt rotational grazing. More specifically, we evaluate the costs that are expected to differ between the two systems (fencing and water infrastructure, and labor) over a suite of initial ranch conditions (contiguous vs non-contiguous ranches, grazed either continuously or rotationally). The livestock weight gain data was used with 20-year cattle market data for Colorado to calculate annual revenues using a model free of inter-annual market effects. Our results indicate that the additional infrastructure required to convert from a continuous to a rotational grazing system makes rotational grazing a financially infeasible option without cost share assistance. However, rotational grazing results in lower labor costs due to the increased stocking density of the herd. We also find that contiguous pasture ranches are significantly more profitable than non-contiguous ranches, a finding that could be especially pertinent to beginning ranchers as well as those looking to expand their operations.

Book Description
Improvement of the world's livestock industry necessitates input from many directions. Planning by a host of national and international agencies is required in order to provide optimal stimulus in very diverse areas ranging from formulation of laws and incentives that stimulate competition yet prevent undue competition, to the optimal provision of credit. Planning is needed to carry out a complex array of interrelated research. The purpose of this book is specifically tasked with setting forth frameworks and methods for evaluation of investments and associated economic decision-making in the livestock industries of developing countries. Economists will find this book useful because it synthesizes .much material into a cohesive whole--material that is often presented in a cursory manner or overlooked as emphasis has shifted to sophisticated quantitative techniques.

Book Description
Benefits and costs of implementing the specialized grazing systems on federal rangelands managed by the Bureau of Land Management (BLM) were studied. First only the direct benefits and costs were used to determine the internal rates of return on the Bureau of Land Management investments in grazing systems. Secondly, the effects of these systems on profits of private ranchers were determined. Finally the benefits and costs stream on the Bureau of Land Management and the changes in ranchers' profits were brought together to find out the net gain to society from investing the federal funds in specialized grazing systems. The internal rate of return on the Bureau of Land Management investments over an area of approximately 695,024 acres in Idaho, Nevada and Utah is 2.37 percent which is less than half the rate federal investments are expected to return (as measured by the federal government's cost of borrowing). More than half of the twenty four allotment plans have negative rates of return. Out of thirteen plans with negative rates of return only five had positive net returns and the rest have negative net returns. Specialized grazing systems have improved the aggregate profits of the private ranchers by

Book Description
This book looks at current knowledge on management of pastures and rangelands for sheep production, of problems, of practical solutions where possible, and of priority areas for research. The areas considered extend from the high rainfall perennial pastures of south-east Australia and New Zealand, through the annual pasture, cropping zones to the semi-arid rangelands. Pasture Management is the major reference on managing Australia's greatest natural resource: the resource which provides directly and indirectly a major part of Australia's export income.

Book Description
"The replacement of perennial grass species by undesirable annual grass weeds not only results in lower productivity but is [sic] also contributes to a range of external costs. In particular, shallow rooted annuals result in greater deep drainage and therefore a greater potential for salinity, and greater volumes of runoff of poor quality water to streams. In this paper an economic framework for examining the sustainability issues of a perennial grazing simulation and dynamic programming models, with the state of the system represented by variables for the perennial grass composition and soil fertility."--Abstract, p. ii.
