in carbohydrates. When it is en-
SIZED, enough sugar ferments to keep
the silage indefinitely, if the silo
is alright.
Grasses and legumes are high in
proteins and low in carbohydrates.
They contain only small amounts of
fermentable sugar. To make grass
silage keep, other preservatives are
necessary. Such preservatives in
clude molasses, dried whey powder,
ground cereals such as corn, or
acids.
With corn prices at present levels,
too great cash outlay is necessary
for the use of 200 pounds of ground
corn needed per ton of grass silage,
farm experts insist.
Grass silage preserved with acids
keeps well, but COWS do not relish it
as they do silage treated with mo-
lasses or dried whey powder. The
acid method was introduced by a
A. I. Virtanen, a Finnish scientist,
in the 1905. The A.I.V. preserv-
ing method, which is named for
him, requires the use of strong min
eral acids. Reports show that these
acids have been destructive of cloth
ing and skin and have corroded silos
and silo filters. Special equipment
is necessary to add the acids by the
A.1.V. method. Phosphoric acid
sometimes is used as a preserva-
tive. When it is used, the silo filler
should be washed out after each
days run.
In past years, molasses has
proved good preservative, but sup
plies continue to be scarce.
Report on Experiments.
Increasing interest has conferred
on whey powder, which is plentiful
and economical, and is easier to ap-
ply than molasses. 1t may be fed
into the silo filler or scattered on
the cut material in the silo. The
amount of whey powder to add de-
ponds to large extent on the type
of legume or grasses to be ensiled,
indicates G. Bohstedt of the agri-
cultural experiment station at Uni
versity Of Wisconsin college of agri-
culture. With two other Wisconsin
research men, w. H. Peterson and
F. w. Duffee, he has studied vari-
Gus grass silages and preservatives.
In general about two-thirds as much
whey powder as molasses is re-
CURED, they learned.
For straight alfalfa and clover,
the Wisconsin men suggest dried
whey powder at the rate of 40
pounds per ton of silage, COM
pared with 60 pounds of molasses.
For legume and grass mixtures such
as clover and timothy, the proper
tons are 80 and 40 pounds, respec-
lively; and for grasses and cereals,
such as timothy, canary grass, oats,
20 and 80 pounds.
Studies by University of Illinois
research men show that whey pow
der has given excellent results. It
contains about the same percentage
of sugar as liquid molasses, and also
contains IL per cent protein, making
it valuable feed in itself.
The three Illinois research men,
w. X. Nevens, X. E. Harshbarger
and K. A. Kendall, report that grass
or legume silage is high in feeding
value.
"Silage made with a grass or
legume," they report, "is better feed
in some respects than corn silage.
1t has a higher protein content;
hence less protein is required in
the grain mixture. And it is higher
in carotene. The carotene tends to
increase the vitamin content and
yellow color of milk. The vitamin A
in milk from cows fed grass or
legume silage may be nearly as
high as that of milk from COWS on
pasture"
The research men point out, how
ever, that in areas with very high
corn yield per acre, such asHllinois,
