Quantification and control of the greenhouse gas emissions from a dairy cow system

In addition, we developed a GHG emission quantification procedure for dairy cow systems based on a life cycle assessment (LCA) approach incorporating the IPCC's GHG emission calculation equations, and set up a relationship between the feed composition and corresponding GHG emissions. Finally, a comparative assessment of the alternative feed compared to the original feed was performed to quantify the reduction of GHG emissions from the dairy cow system in order to select the most desirable feed composition.
