often be noticed a halt mile on each side of the silo. It is well, there-
fore, to delay cutting until the corn is nearly ripe when the dry
matter is all deposited and the sugars are changed to starch.
Legumes can be siloed without cutting but better success follows
cutting. Corn should be cut into short pieces or shredded. The latter
n.ethod is more favorable than the former. The smaller the pieces the
better it will pack in the silo. Too much emphasis cannot be placed
on the importance of thorough tramping, especially around the outside.
Water sufficient to fIl the spaces should be added. No danger attends
the addition of large quantities. Silage is preserved on the same
principle that rhubarb is kept in water in Mason jars. The acid com-
ing from the material to be preserved destroys the bacteria that en-
tered with the material and the water. The air-tight mass prevents
the entrance of other bacteria. And since, therefore, no living bacteria
are present, no decay takes place and the silage keeps. It will be no-
ticed, therefore, that bacteria must be kept out. This requires, as
stated before, thorough packing, the filling of the air spaces with
water and an air-tight containing wall. Losses occur in the silo due
to fire fanging and rotting. This is, of course, greatest at the top
of the silo. Filling the top with water and seeding grain has proved
the best means of protecting the top. Usually when the silo is filled
the pastures are short and it is expedient to begin feeding silage at
once after filling. When this is done there is no loss from this source.
.A reduction in the dry matter due to oxidation occurs and some of
the proteid substances are changed to amide forms; a condition In
which the proteid is less digestible. King found that the total loss
need not be greater than 10%.
Comparing the losses from giloing corn with fodder, the experiments
of four stations show the following results:
