Book Description
Life Cycle Assessments (LCAs) are quantitative analyses of complex systems for evaluation of impacts and risk associated with management decisions. LCAs can be effective tools for determining comparative advantages of management strategies across specific impact concern. In this study, life cycle assessments of pork production management alternatives was performed. The alternative management practices included in this study were production of entire males (boars), use of pens for gestation housing, immunocastration, production without growth promoting antimicrobials, production without growth promoting and preventive antimicrobials, and production without ractopamine. These LCAs evaluated the impact of each management strategy on greenhouse gas emission (GHG), cumulative energy use, and cumulative water use compared to the common baseline. Each alternative management strategy was simulated in Pig Production Environmental Footprint (PPEF) model by varying key variables. Life cycle inventory inputs for unit process created using PPEF model were used for SimaPro V7.3 (Pre' Consultants, The Netherlands), an LCA modeling program. The functional unit for the analysis was one kilogram live weight at the farm gate. Influence of temperature on impact categories was evaluated by testing all alternate management practices at five temperature regimes. While, temperature influenced the changes to the impact categories, hypothesis testing was performed for alternative management practices for scenario at Wright County, Iowa that used typical meteorological year to control temperature inside the barn. LCAs of alternative management practices yielded a range of results. Increase in GHG emissions, cumulative energy use, and cumulative water use were observed for no growth promoting antimicrobials (1.559, 1.746, and 1.038% respectively), no growth promoting or preventive antimicrobials (17.321, 18.399, and 15.577% respectively), and removal of ractopamine (6.515, 4.867, and 7.518% respectively) scenarios. For entire males scenarios GHG emission and cumulative energy use increased by 2.092 and 3.748% but cumulative water use decreased by 2.294%. Lower GHG emissions, cumulative energy use, and cumulative water use were observed for gestation pens (0.973, 1.499, and 0.972% respectively) and immunocastration (2.385, 2.567, and 2.963% respectively) scenarios. These changes could be concluded with at least 75% confidence only for lower water consumption for entire males, decreased GHG emissions and water consumption for immunocastration, increased cumulative energy consumption for no growth promoting antimicrobials, increase in all three impact categories for no growth promoting or preventive antimicrobials, and increased GHG emissions, cumulative energy and cumulative water consumption for removal of ractopamine scenarios. A null hypothesis that changing management practices in the pork production in the US does not affect impact category metrics used for sustainability assessment was rejected using one tailed paired t-test at P

Book Description
Among the first creatures to help humans attain the goal of having enough to eat was the pig, which provided not simply enough, but general abundance. Domesticated early and easily, herds grew at astonishing rates (only rabbits are more prolific). Then, as people spread around the globe, pigs and traditions went with them, with pigs making themselves at home wherever explorers or settlers carried them. Today, pork is the most commonly consumed meat in the world—and no one else in the world produces more pork than the American Midwest. Pigs and pork feature prominently in many cuisines and are restricted by others. In the U.S. during the early1900s, pork began to lose its preeminence to beef, but today, we are witnessing a resurgence of interest in pork, with talented chefs creating delicacies out of every part of the pig. Still, while people enjoy “pigging out,” few know much about hog history, and fewer still know of the creatures’ impact on the world, and specifically the Midwest. From brats in Wisconsin to tenderloin in Iowa, barbecue in Kansas City to porketta in the Iron Range to goetta in Cincinnati, the Midwest is almost defined by pork. Here, tracking the history of pig as pork, Cynthia Clampitt offers a fun, interesting, and tasty look at pigs as culture, calling, and cuisine.
