With the alley finished, begin the construction of the floor of the
stalls proper. For the average sized cow, the usual length of stall is
4 feet 8 inches from stanchion to drop gutter and the width is 3 feet
6 inches. The stall floor should slope not less than ½ inch toward
the drop gutter to provide for drainage. If an adjustable stanchion
fastener is to be used, set it in the center of the 6-inch manger wall.
The length of the stall is regulated by this device. For a stall 4 feet
8 inches long, set the outside board (2 by 12 inches) of the manger
wall 5 feet 2 inches from the drop gutter. The top of this board will
be 7 inches above the finished floor. This extra height provides a form
for the manger wall. In this space, place the 5-inch floor in the same
manner as the alleyway was laid. If gas pipe stall divisions are to be
used later, make mortises in the floor at the proper points by tamping
the concrete around a core of the right size, removing the core when
the concrete has stiffened.
