Data Obtained from the GreenFeed System
As GreenFeed is used in the field, and data is collected, new potential uses of the data are
even still being discovered. For example, as highlighted in
Figure 2 , an animal enters the
feeder and does not immediately eructate. However, the concentration of methane
increases a small amount before an eructation occurs. We believe that this increase is
associated with methane expelled through the lungs, which is a normal part of the
physiological process in the animal. It therefore should be possible to estimate the ratio of
lung methane compared to eructated methane.
Once GreenFeed collects the data, the data is automatically processed and the results are
calculated for each animal. A daily report for the herd average and animal specific emissions
is emailed to the user. The user can access the controls for the feeder through a
user-friendly, secure, web-based interface.
