The GreenFeed Standard Operating Procedure was developed for the use of the GreenFeed system. GreenFeed is a nonintrusive system for estimating methane and carbon dioxide fluxes from cattle. This manual provides an overview of cattle gas emissions as a base for understanding GreenFeed operations, and describes the physical operation, controls and maintenance, calibration, and data flow of the GreenFeed system.
