Description: The bunker silo in the image above has a moveable roof, which protects the silage from rain or snow after the silo has been opened. During filling the roof can be moved forward along the silo to make head room to allow the forage to be packed by a tractor. The walls of this silo are made of concrete panels that are eight feet high by ten feet long and at least five panels are visible. This silo would hold about 95 tons of silage at 35% dry matter compressed to 40 lb/cu.ft. See Bunker Silo Management, J. A. Salfer and J. G. Linn, http://www.ansci.umn.edu/dairy/dairyupdates/du109.htm This would be sufficient forage for only ten cows and five growing heifers so it would be one of several silos on a typical dairy farm of 100 cows. This silo is too narrow for adequate packing. Silos should be a minimum of twice the width of the packing tractor and should not be less than 16 feet wide (see Salfer and Linn.)
