NITROGEN AND OTHER LOSSES IN ENSILING CORN 3 
Woll (6), in another paper, gives additional data on silage studies 
taken up at the Wisconsin station. His summary of results for three 
silos indicates that he found a 37.15 per cent loss in albuminoid nitro- 
gen and a 46.7 per cent gain in amido nitrogen during ensiling. 
Short (7), in 1888, at the Wisconsin station finds during the ensil- 
ing of maize in three silos an average loss of 15.94 per cent of the 
dry matter and 21.26 per cent of the crude protein ensiled. 
Woll (8) , summarizing three years' work, including 10 experiments 
in which the comparative losses in ensiling and field-curing green 
maize were studied, reports that by ensiling there was a loss in the 
total dry matter of 20.5 per cent and in the crude protein of the green 
corn a loss of 20.6 per cent. He used silos holding 8 to 12 tons of 
silage. 
In the fall of 1890, Woll (9) continued his experiments on the com- 
parative losses in ensiling and field-curing green corn. He states in 
the report for the year ended June 30, 1891, that with a large rec- 
tangular silo of 80 tons' capacity, he found in the 65 tons of maize 
ensiled a loss of only 10.3 per cent in the total dry matter, and of 
12.5 per cent in the crude protein. He attributes the larger losses of 
previous years to the smaller quantities of maize ensiled. 
F. H. King (10), of the Wisconsin Experiment Station, in connec- 
tion with his experiments to determine the necessary loss of dry mat- 
ter in maize silage, studied the losses of total green material and total 
dry matter. Including all material taken out, whether good or 
spoiled, he finds in one year, in approximately 65 tons of maize 
ensiled, a loss of 7.35 per cent of the green matter and 4.95 per cent 
loss of the total dry matter. In the next year he finds a 5.78 per 
cent loss of green matter and 9.38 per cent loss of the total dry 
matter. He concludes that the loss may vary with the maturity of 
the maize at the time of ensiling. 
Cooke (11) , in the earliest investigations with maize silage reported 
from the Vermont Experiment Station, describes an investigation 
with an experimental round stave silo holding about 350 pounds of 
corn, covered by a follower under a pressure of 50 pounds per square 
foot. He states that the corn was cut while in the glaze and the silage 
was in perfect condition when taken out. His tables indicate a loss 
of 14.67 per cent of total dry matter ; a loss in albuminoids, crude fiber, 
and nitrogen-free extract ; and a gain in the fat of the maize ensiled. 
Cooke and Hills (12) , in a comparative study of the losses in maize 
silage and maize fodder, using a square wooden silo holding 12 tons, 
find a loss during ensiling of 20 per cent of the total dry matter, 13 
per cent of the albuminoids, and 31 per cent of the sugars and starch 
in the maize ensiled.
