Bee-Sting Factor
Preserves Silage
Formic acid, a naturally oc
curring compound that puts
the "ouch" in a bee sling, may
also help cattle gain weight, a
U.S. Department of Agricul
ture scientist reported recently.
Cattle fed unwilled silage
don’t gain well. This is be
cause they don’t like to eat
much of it, Dr. Dale R. Waldo,
a USDA cattle nutritionist,
told Die annual meeting of the
American Dairy Science Associ
ation in Ithaca, N.Y.
An average of three trials
conducted in 1965 and 1966,
however, shows that silage
treated with formic acid sus
tained dairy heifers so well
that they gained 11 percent
faster than heifers fed hay cut
from the same field. Since heif
ers on treated silage got no
more digestible energy than
those on hay, the digestible
energy in treated silage must
have been used more efficient
ly, Waldo said.
That may make formic acid

look doubly attractive to the
cattle producer. First, it makes
silage production practical
where wet weather prevents
field wilting, because treat
ment overcomes the low taste
appeal of unwilled silage. Sec
ond, cattlemen can count upon
increased energy value from
their feed.
Returns, although consistent
ly good, have varied, the nu
tritionist reported. In a 1966
trial with alfalfa, heifer gains
with treated silage were 15
percent greater than with hay.
In a 1965 orchardgrass trial,
the advantage was 14 percent.
And in a 1966 orchardgrass
trial, four percent. Waldo hopes
to further clarify the economic
advantages of formic acid.
Formic acid, found natural
ly in bee venom, is also avail
able as an industrial chemical.
The cost of Waldo’s treatment
(one pound of undiluted 90
percent synthetic commercial
formic acid per 200 pounds of
orchardgrass) is $2 per ton,
but he hopes that further stud
ies on the amount and method
of application will i educe the
cost.
