a few stalls for use in milking. This style is well adapted to 

 certified milk production, as each cow may be groomed before

The Foundation. The foundation for a dairy barn should 

 extend below frost and should be on firm soil. The width of 

 footing may vary from 12 to 16 inches. An 8-inch founda-

 strong; a wall of rubble work should be wider. Sills should 

 be 12 to 15 inches above the floor.
