If your system included a freestall cart, each of the 4 feet include a hole drilled into them. In
addition, each corner has a metal loop. These are meant as a way to fasten the cart to the
ground with anchors, rebar, and/or chains. See Figure 5.

2.3. Setting Up Alleyways
Alleyways are crucial for GreenFeed to ensure that only one animal can access the system at
a time. If multiple animals are present, the system cannot separate the emissions and
attribute them to each animal.
In addition to alleyways, a solid wall must be used to ensure other animals cannot breathe
into the system during a visit. Some examples of alleyway setups are shown below in Figures
6 and 7.
