Interpretive Summary:

Technical Abstract: This article discusses the issue of porosity (i.e., the portion of volume filled with gas) in silages. As porosity increases, the silage is subject to greater losses. Porosity can be reduced by adequately packing the crop at ensiling. To keep porosity below 40% a minimum bulk density of 44 lbs./cu. ft. is needed.
