Dr. Higgins developed and installed a Bo Renfro style structure on the concrete pad. When we installed the gates inside the barn, we planned the layout so that each pen could have access to the feeder on the concrete pad simply by opening the gate. In addition, we positioned the gates around the barn for multiple pastures to have access to that feeder. You can see the amount of access points below.
Before we installed the permanent structure, we tested the design and dimensions with a similar structure that was built out of temporary feed panels. The cows pushed the panels around and we lost some hay to trampling and moisture. Here is the temporary structure we used initially. (Click on an image to enlarge it)
Once we finalized the dimensions, we installed the permanent structure made out of concrete and posts. The permanent structure wastes less hay, as the cows aren't able to move the panels around, and the center is raised 6 inches to keep the wet slop on the ground from contaminating the hay. This structure can hold 6 round bales. You can also easily feed concentrate diets in this feeder by putting feed bunks inside the feeder when it is not being used for hay. The PVC sewer pipe was added to allow for wet wrapped hay to be pushed into the feeder. The wet wrap bales are much heavier and we found we needed the pipes to be able to fill the feeder with 6 wet wrap bales end to end. If you are feeding dry hay only, the sewer pipe is not necessary.
In addition, we created a manure stack pad on another part of the existing concrete with large concrete blocks.
