The US Pig Production Environmental Calculator (PPEC) was built upon cradle-to-farm-gate life-cycle assessment (LCA) of pork production combined with the US National Resource Council (NRC 2012) swine nutrient requirements models (NRC 2012), farm operation inputs, and animal feed database. The purpose of the US Animal Feed Database is to compile environmental, economic, and nutrient content of animal feed ingredients in a single location and integrate it into a PPEC economic model of swine operations. (Click on image at right to view a handout of the poster).
We collected data from different sources including NRC (2012) feed nutrient characteristics, Feedstuffs (2014) for feed prices, US agricultural and product LCA models built in SimaPro 7.3.3 (PRé Consultants 2011) and LCA databases (Swiss Centre for Life Cycle Inventories 2010; EarthShift 2011; Blonk Consultants 2014) for environmental footprints. Table 1 shows a list of top US pig feed ingredients.
Feed ingredients with highest costs are additives (e.g. paylean) and amino acids. Milk by-products have the largest climate change impact, water and land use.
The information from this database will be used as a starting point for identifying potential mitigation options in pig diet formulation. The database will be updated as new information becomes available.
