Summary and Implications
Energy is used in all aspects of pig production, from the manufacture of materials used in building construction to the cultivation and processing of feedstuffs. Historically the availability of fossil fuels has minimized pressure to consider all uses of energy in pig production. Rising energy prices, uncertain access to petroleum supplies, and recognition of the environmental impacts of fossil fuels are increasing awareness and incentive to reduce consumption of limited resources. Comprehensive, accurate information is critical to informed decision making. Analysis of energy use by modern pig farms in Iowa, the Midwest, and the U.S. is needed.
The project focuses on pig production–cropping system interaction with methodology developed through the project that will be adaptable to evaluating energy consumption and ecological impact of other livestock systems. This project addresses a need for energy and resource use information by policy makers and community members as they strive to make informed decisions.
