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 soluble-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 
furf urol-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 probably 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.
