silo, since the presence of air causes undesirable decompo- 

 sition. Silage is a succulent food, not drv food like hay. 

 In making silage part of the dextrose is converted first to 

 alcohol, then to acetic acid; part is converted to lactic acid. 

 The total acidity is never more than 2 per cent. Proteins 

 are converted in part to amides, and even to ammonia. 

 Crude fiber is made more digestible, probably by hydrolysis. 

 Compounds like volatile oils are also formed. Finally about 

 10 to 15 per cent, of material is lost because of complete 

 oxidation of part of the material to carbon dioxide and 

 water.
