Book Simulation Of Beef Cattle Production Systems And Its Use In Economic Analysis

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.

Book The Development of a Modeling Platform to Examine Management Alternatives to Improve the Sustainability of Beef Production

Download or read book The Development of a Modeling Platform to Examine Management Alternatives to Improve the Sustainability of Beef Production written by Robin Rosemarie White and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research was to develop a modeling platform to test the effects of management practices on sustainability of beef production systems. A simulation model was constructed to examine the role of improved efficiency on environmental impact (land use, water use and greenhouse gas emissions; EI) of beef production systems while increasing economic viability and consumer willingness to pay (WTP). An optimizer was developed to adjust cattle diets to minimize whole-system EI while constraining production costs within the bounds of consumer WTP. Cradle-to-farmgate EI and production costs were calculated following the simulation model. Consumer WTP for environmental attributes of beef was determined by meta-regression of published estimates of consumer WTP. The validated model was then used to assess how nutritional, reproductive and genetic management could help improve sustainability. Nutritional management alone reduced EI by 2%. Twinning or decreasing the calving window decreased EI by 17% or 11%. Selected bulls by expected progeny difference reduced EI by 18%-19%. Finally, Bayesian analysis was used to quantitatively summarize consumer WTP for environmental attributes of meat. The model predicted U.S. consumers WTP ranged from 6.7% to 32.6%. The confidence range was used to predict probability of consumer purchase across the schedule of WTP. When probability of purchase was ignored, this range in WTP equated to a maximum 65.5 L/kg beef reduction in water use when beef cattle diets were adjusted. When probability of purchase was factored in, a 10% increase in WTP optimized theoretical opportunity to decrease EI, netting a 41.4 L/kg beef reduction in water use. A novel model was successfully developed and used to assess the role of specific management practices and their use in improving beef production sustainability. Optimizing nutritional management, including reliance on precision pasture management, while concurrently improving genetic and reproductive efficiency, substantially improved sustainability. Additionally, when relying on WTP as a method of incentivizing adoption of environmental-impact reducing management practices, focus should be put on obtaining market share rather than sacrificing cost in an attempt to reach the biological ideal opportunity to minimize environmental impact.

Book Alternative Beef Production Systems

Download or read book Alternative Beef Production Systems written by Kenneth H. Mathews, Jr. and published by . This book was released on 2013-05-09 with total page 34 pages. 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.

Book Computer Simulation of Beef Cattle Production Systems in the Llanos of Columbia

Download or read book Computer Simulation of Beef Cattle Production Systems in the Llanos of Columbia written by Joel Martin Levine and published by . This book was released on 1979 with total page 570 pages. Available in PDF, EPUB and Kindle. Book excerpt: A simulation model capable of execution on a programmable calculator was developed to study voluntary intake, liveweight change, and fertility of grade Zebu cows in the Llanos of Colombia. Organic nitrogen in the diet and meta bolic weight were used to predict intake; age, liveweight, and energy concentration were the driving variables for the maintenance prediction equation. Energy concentration was calculated as a function of crude protein and digestible organic matter, and liveweight change was predicted as a function of intake, maintenance, liveweight, and energy concentration. Multiplicative correction factors were fitted from data obtained from cow-calf experiments to adjust intake and maintenance for the effects of burning the native savanna, compensatory gain, mineral deficiency, and lactation and gestation. The correction factors were .89 for intake after burning the native savanna, 1.05 and .95 for intake and maintenance during compensatory gain, and .90 for reduced intake due to mineral deficiency. Correction factors for physiological status were 1.20 for intake during early and late lactation, and 1.40, 1.32, and 1.05 for maintenance during early lactation, late lactation, and late gestation, respectively. The correction factors for burning and compensatory gain were fitted against data from dry cows of Herds 4-5 of the Herd Systems Experiment (HSE) and yielded a Pearsonian correlation coefficient of .95 (p
