NITROGEN AND OTHER LOSSES IN ENSILING CORN. 15 



CONCLUSIONS. 



The two years' work furnishes evidence of a downwash of the juice 

 in the silo, carrying with it sohible-food materials, so that the silage 

 in the lower part of the silo may gain in food material at the expense 

 of the upper part. 



There was an average loss for all the bags of nearly 10 per cent of 

 the dry matter, which apparently is due largely to the fermentation 

 of the carbohydrates and to the carrying away of soluble material 

 by the juice. The reducing and nonreducing sugars almost entirely 

 disappeared. There was a considerable loss in crude fiber and in the 

 furfurol-yielding bodies. 



There was a loss in total nitrogen, It is probable, however, that 

 this loss is due largely, if not entirely, to the nitrogenous compounds 

 which escaped in the juice. The albuminoid nitrogen suffered a loss 

 of over 50 per cent, while the nonalbuminoid forms increased several 

 times their own weight. 



There was a gain in ether extract, which is probabl}^ due to the 

 formation of new ether-soluble bodies. 



The juice which was collected the second season amounted to nearly 

 10,000 pounds. This juice averaged 0.263 per cent total nitrogen, 

 0.0283 per cent albuminoid nitrogen, and 317.9 parts ammonia nitro- 

 gen and 1,472.9 parts amino nitrogen per million.
