CONCRETE SILOS 
"Silage will keep, if properly put up in a good silo, from 3 to 4 years. 
Silage does not 'cook.' It ferments and it does not matter whether there 
is 6 inches of concrete, 2 inches of wood, 3^ inch of iron, or 
Temperature ^^^t kind of construction is used in the walls. The heat is 
o" Silage ' '^^ caused by the fermentation and the loss through the walls is so 
small that it is entirely negligible. The temperature due to 
fermenting may rise to 130 to 140 degrees Fahrenheit. 
"A silo that is air tight will hold the moisture. There is nothing more 
mysterious in putting up silage than there is in putting up sauer-kraut. 
The confusion arises usually because agents of different kinds of silos try 
to make differences where none exist." — Hoard's Dairyman, Ft. Atkinson. 
A Wisconsin dairyman writes to "The Farmer" of St. Paul, asking if it 
is true that dairy cows fed on silage live only about five years. The 
answer is: 
Prolongs "There is positively nothing in such a report; as a matter 
Cows' Lives of fact, cows fed silage will generally outlive cows that are not 
fed silage or some other such succulent feed. 
"The Minnesota Experiment Station of St. Paul has a greater 
number of records of old cows than perhaps can be found anywhere 
else in the United States; that is, cows that were raised from calves 
and continued in the herd until they died of old age, most of them over 
fifteen years and profitable to the last year. These cows are fed silage 
the year around, from twenty to forty pounds a day. This is surely 
evidence that cows will live their natural life when fed on silage."
