NITEOGEN AND OTHER LOSSES IN ENSILING CORN 3 



WoU (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 

 com 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 j^ounds per square 

 foot. He states that the corn was cut while in the glaze and the silage 

 Avas 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 allmminoids, and 31 per cent of the sugars and starcli 

 in the maize ensiled.
