Available in PDF, EPUB and Kindle. Book excerpt: The optimum forage handling system for a farm firm is not necessarily the one minimizing machinery costs. Consideration must be given to the interdependence of all systems on the farm in order to select a forage harvesting and handling system that permits the farm operator to maximize his net returns. The objectives of this thesis were to compile existing data pertaining to forage handling, to computer simulate some of the present alternative systems applicable to forage harvesting and handling, to test the suitability of the General Purpose Simulation System/360 (GPSS) in generating and costing such systems, and to propose other mathematical methods of evaluating alternative systems. It was premised that legume-forage crops in the Edmonton area are primarily grown and harvested for their protein value. The objective function of this cost-benefit analysis was therefore defined as minimum cost per ton of digestible protein fed. The method used to generate and cost alternative systems involved both network analysis and simulated sampling techniques. The GPSS programs randomly selected alternative routes through the network, simulating several years of harvesting weather for each, and calculating fixed, variable and penalty costs incurred as the forage moved from field to exit from storage. Penalty costs associated with harvesting delays and weather damage were assessed using weather probability functions, a simulated sampling of harvest weather, and a cost calculation of lost feed value. Some program parameters were given a uniform probability distribution of values. Annual fixed, variable and penalty costs were calculated for each stage of the system before another pass was made through the network. The analysis of these simulated systems showed that, for many systems, penalty costs per harvested acre comprised a significant proportion of total annual costs. Thus, a knowledge of how nutritional values and drying rates of mechanically treated forage relate to weather parameters is important. The lack of this information constitutes a serious data gap. After the simulated systems were ranked in accord with the predetermined objective function, the cost sensitivity of the systems became apparent. In the section of the network successfully programmed, one of four different end products was selected for each route - high moisture silage, wilted silage, haylage and dehydrated forage - the general advisability of each ranked in the same order. Within the reliability of data and sample sizes used, no one system was always preferable to the one next in rank. Cost distributions for systems overlapped to a considerable extent. The suitability of the GPSS approach is questionable. The trade-off existing between computer time and storage requirements will influence the selection of an alternate method. Any comparative evaluation of forage harvesting and handling systems requires simulated sampling at some point in the analysis, unless stochastic variables are approximated with constant values. Three other possible mathematical methods that could be used are (1) simulated sampling and separable programming, (2) Shortest Path Network Analysis (SPNA) and Monte Carlo techniques, and (3) dynamic programming and simulated sampling. This latter possibility eliminates the necessity of evaluating every possibility in the network.

Download or read book Quality and Production of Forage written by Vincenzo Tufarelli and published by MDPI. This book was released on 2019-10-29 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book "Quality and Production of Forage" is intended to keep readers updated on the developments occurring in this field. As it is apparent that livestock animals are important throughout the world because of the meat, milk and egg they produce, knowledge about the forages available to animals must also be considered for increased production, quality and efficiency. This book provides information that readers will find considerably invaluable about forage feeds, such as grass, legumes, and straw. The book is composed of ten papers, focusing on a wide range of research activities and topics that feature the following concepts of forage: the effect of conservation method on forage protein value; Microbial the composition and mycotoxin content in forage; genetic diversity of forages; timely sowing to maximize yield for both grain and biomass; ensiling treatments on forage quality; the qualitative characteristics of different accessions of new forage species; forage policy influencing feed costs; feeding forage on animal health; high-protein tropical forages as alternative sources for poultry; impact of forages in poultry diet and significance of forages in sustainable poultry production systems. This book will be an invaluable reference for students and professionals in agricultural science and grassland and animal husbandry researches.

Download or read book Grass for Dairy Cattle written by Jerome Henry Cherney and published by Cabi. This book was released on 1998 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the current interest in the environmental and economic sustainability of dairy farming, grass forage crops have emerged as a potential solution to some of the nutrient management problems now encountered on intensively managed dairy farms. The expansion and reintegration of grass-based systems into the mainstream of dairying systems will require a major paradigm shift involving economic, social and ecological, as well as biological factors. This book examines the role of grass in milk production in sustainable agricultural ecosystems. It provides a current summary of the role of grass in dairy cattle systems, including the breeding, management, storage, feeding and economics of grass for both lactating and dry dairy cows. Written by leading specialists from Australia, Europe, New Zealand, North and South America, this is an essential reference source for researchers, dairy industry professionals and advanced students of forage and dairy cattle nutrition.

This book was released on 2012-12-06 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Oata Analysis and Synthesis (CINOAS) * at Purdue. University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 33 (thesis year 1988) a total of 13,273 theses titles from 23 Canadian and 1 85 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 33 reports theses submitted in 1988, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.
