The supposed effect of silage acid on concrete has been one of the 
most widely discussed and at the same time the most absurd of the many 
common silo fallacies. Silage acid is one of the weakest acids 
Unaffected known to science. It does not miraculously preserve wood nor 
by Silage destroy concrete, neither does it affect cows' teeth nor their hoofs 
or horns. It does not eat out their stomachs and has no bad 
effect upon them whatsoever. Silage juices will not eat away concrete 
nor injure it in the slightest degree, which is proven by the fact that after 
years of service the concrete foundations of hundreds of silos built of other 
rnaterial still show, to-day, the trowel marks which were made at the 
time constructed. If the silage acid had any effect whatsoever, it would 
only be a few months when the floor (of all places) would show the effects. 
Many a dairyman, who has successfully fed silage to his cows for 
years, is told by his neighbor who raises sheep or hogs that silage is all 
right for dairy cows but it is not good for his animals. This, of 
Required course, is absurd, but it should be remembered that the stomachs 
in Feeding animals like cows (which have four stomachs holding 40 or 50 
pounds of silage in 24 hours) are different from the smaller and 
more delicate stomachs of horses or sheep. Hogs relish silage but they, 
again, have different kinds and sizes of stomachs than the other animals 
mentioned. Silage is also fed to chickens and other poultry with great 
success. It might be mentioned, at this time, that the average silage 
ration for cattle runs from 30 to 50 pounds daily; for horses, not as a rule, 
over 15 pounds and the silage must be of excellent quality, as the horse is 
a dainty feeder; for sheep, not over 3 pounds daily; for hogs, from 3 to 5
